Not only is growth in Brisbane’s unit market lasting longer, it’s also getting stronger.

In August, unit values climbed a further 1.3 per cent, one of the strongest monthly results the Queensland capital has recorded in 2025, pushing the median unit value beyond $740,000, according to Cotality’s latest Home Value Index.

Over the rolling quarter, unit values surged 3.9 per cent, and are now 11.1 per cent higher year-to-date,&nbsp;making Brisbane the strongest-performing capital city unit market in the country.

The city’s apartment sector is also comfortably outpacing detached housing in 2025. House values rose 1.2 per cent in August to reach a median of $1.04 million, but quarterly growth was softer at 2.9 per cent, with an annual gain of just 7.3 per cent.

This widening divergence highlights the relative affordability of apartments and the intensifying demand for medium-density housing amid constrained supply,&nbsp;a trend reshaping Brisbane’s property market.

&nbsp;

<h2>What happened in Brisbane’s off the plan apartment market in August?</h2>

It was a busy month in Brisbane's off the plan property market, with new projects coming to the market, new projects and approved, and some hitting major construction milestones.

&nbsp;

Gold Coast developer <a href="https://www.apartments.com.au/developers/sherpa-property-group">Sherpa Property Group</a> revealed its debut Brisbane apartment development to the market, starting to take expressions of interest for&nbsp;<a href="https://www.apartments.com.au/new-apartments/symphony-south-brisbane-21-23-cordelia-street-south-brisbane-qld-4101">Symphony</a>&nbsp;in South Brisbane.&nbsp;

The 138-apartment development, part of Sherpa’s affordability-focused Flourish brand, is located near Fish Lane and aims to deliver quality homes at more accessible price points.&nbsp;

[smartcode_project:default project_id=7574 project_image_fid=3444]

Symphony’s one-, two-, and three-bedroom apartments will start from $655,000, with eligible first-home buyers benefiting from Queensland’s new stamp duty exemptions.&nbsp;

Over 1,400 sqm of communal amenity, including workspaces, rooftop pool, wellness centre, and private dining, will support a lifestyle-driven community.&nbsp;

City Beat August 2025: Brisbane unit values surge again in August, as two new apartment developments launch to market

Summit &amp; Ridge, the fourth stage of Sekisui House Australia's Sanctuary in Wentworth Point, secured a flurry of sales at its recent launch.

More than 80 per cent of purchasers of&nbsp;<a href="https://www.apartments.com.au/new-apartments/summit-ridge-at-sanctuary-wentworth-point-14-16-hill-road-wentworth-point-nsw-2127">Summit &amp; Ridge</a>&nbsp;were owner occupiers, underlining the strong demand from buyers looking to live within the new&nbsp;riverfront community. Over 40 apartments were sold valued at $46.5 million within three hours of the launch event, with an average price of $1.107 million.

“Buyers appreciated the larger layouts in this stage and the sense of space Summit &amp; Ridge offers,"&nbsp;said Matthew Landa, Senior Sales Executive – Apartments &amp; Mixed-Use Developments.

"The combination of generous apartments, exclusive amenities and unique position on the Parramatta River peninsula helped with sales. Many told us they could picture themselves living here, it is a place that feels established, green and connected, yet private."

The launch drew interest from local buyers within a 5km radius, as well as repeat purchasers from previous Sanctuary stages, with 15 per cent of buyers upgrading their property portfolio through Sekisui House Australia’s Rewards Program. Purchasers also came from the Lower North Shore, Oatlands and the Inner West, highlighting the project’s broad market appeal.&nbsp;

<img alt="Summit &amp; Ridge at Sanctuary, Wentworth Point" data-entity-type="file" data-entity-uuid="1166d1aa-e075-429c-a1f4-4861cad140e3" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/2417_TheSanctuary_02_EXT_Podium.jpg?VersionId=E37Ym7TBhQX4VFKnFNDwccSiDLp81KZA" />

Comprising 488 apartments across Summt (39 levels), and Ride (32 levels), the first sales release focused exclusively on one and two-bedroom residences, priced from $720,000 to $1.3 million. One-bedroom apartments were popular, with purchasers valuing their limited supply, pricing and uninterrupted views across the Newington Nature Reserve, Parramatta River and picturesque views across the Blue Mountains.

Summit &amp; Ridge enjoys an enviable position on the <a href="https://www.apartments.com.au/developments/wentworth-point-nsw-2127">Wentworth Point</a> peninsula, the only built environment north of Hill Road, surrounded by water and a nature reserve. The project’s Neighbourhood Green, a 1.5-hectare landscaped parkland running through the heart of Sanctuary will also open soon.

The towers by acclaimed architects <a href="https://www.apartments.com.au/architects/turner-studio">TURNER</a> are defined by organic, sculptural forms that frame views, guide movement and enhance the connection between nature and the city, a design approach that ensures Summit &amp; Ridge will become a striking architectural marker within Sydney’s skyline.

<img alt="Summit &amp; Ridge at Sanctuary, Wentworth Point" data-entity-type="file" data-entity-uuid="49e681c8-af8e-4623-aa60-7573acaade7e" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/CGI1.png?VersionId=EkqjP9veHDeZaSeXkN8p1aOUW79nLdVv" />

Summit will feature resident-only amenities on level 29 including a resort-style pool and sauna, while Ridge offers an outdoor cinema, sunset bar and dining space on level 23. At the base of Ridge, a 110-place childcare centre will further support growing families, reinforcing the masterplan’s focus on lifestyle and community.

The interiors in the project by <a href="https://www.apartments.com.au/interior-designers/henderson-co">Henderson &amp; Co.</a>, were inspired by the “natural elegance” of Sanctuary’s landscape setting, with efficient Japanese design principles enhancing space and light throughout the homes. 
&nbsp; 
“The fact that sales were achieved so quickly shows the strength of demand for quality, well-designed apartments in Sydney,"&nbsp;Landa added.

"Owner occupiers in particular see the long-term value of being part of a master planned community delivered by Sekisui House Australia, and that trust has been a major driver behind this success."

Sales momentum was further supported by the current downward trend in interest rates, creating favourable conditions for buyers.

The recent completion of the third stage of Sanctuary, Laguna &amp; Glade,&nbsp;has further reinforced purchaser confidence, giving buyers a first-hand view of Sekisui House Australia’s build quality and design execution.

Nearby amenities include Marina Square Shopping Centre, Wentworth Point High School, ferry terminal, train station and the future Parramatta Light Rail.&nbsp;

Three and four-bedroom apartments will be released at future launches. &nbsp;Construction is anticipated to commence in Q4 2025 and completed by Q3 2028.

Every apartment in Summit &amp; Ridge will carry a 4 Gold Star iCIRT rating, an independent NSW Government-backed accreditation for integrity, capability and financial stability, giving buyers confidence they are investing in a home built to last.

Plans to transform the former VicRoads site in Kew are progressing with four shortlisted developers invited to submit their proposals for the site.

<a href="https://www.apartments.com.au/developers/riverlee">Riverlee</a>, <a href="https://www.apartments.com.au/developers/lendlease-development">Lendlease Development Pty Ltd</a>, <a href="https://www.apartments.com.au/developers/mirvac">Mirvac Group</a> and a <a href="https://www.apartments.com.au/developers/milieu-property">Milieu</a>-led consortium have been invited to participate in the Request for Proposal (RFP) process to deliver much needed housing at 60 Denmark Street, Kew.

Acting Executive General Manager Housing, Nemesia Kennett, said the RFP stage follows a strong response to the initial Expression of Interest (EOI) campaign.

"Denmark Street, Kew, presents a unique development opportunity which has attracted high caliber developers well qualified to transform the site,"&nbsp;Kennett said.

“Each shortlisted developer brings a depth of expertise and proven track record in delivering quality housing projects, achieving excellence in design and community outcomes. We’re looking forward to seeing the shortlisted developers' proposals and understanding how they will deliver the best outcomes for the community if successful."

Local views and priorities for the site were captured in a Community Aspirations Report that will guide the next stage of the development process.

"The report found overwhelming community support for redevelopment of the site and recognition of the urgent need for more homes in Kew,"&nbsp;Kennett added.

“Feedback also highlighted opportunities to revitalise public areas, improve walking and cycling connections, create more green open space, and celebrate the site's heritage, including its rail history and Wurundjeri cultural stories.”

Development Victoria will continue to communicate with the Boroondara Council and the local community throughout the transaction process.

A preferred development partner will be confirmed in 2026, following a thorough assessment of proposals.

Developers shortlisted to deliver housing in Kew

Builder-developer ALAND has drawn back the curtain on its first city-focused new apartment development.

The North Sydney development, <a href="https://www.apartments.com.au/new-apartments/the-walden-north-sydney-173-179-walker-street-north-sydney-nsw-2060">The Walden</a>, is the first time the company has ventured this close to the city, having previously completed thousands of apartments predominantly in Sydney's west, and more recently in Gosford.

<a href="https://www.apartments.com.au/developers/aland">ALAND</a> acquired the prime North Sydney site, spanning Walker and Hampden Streets just down the road from the Victoria Cross Metro station, for $240 million in June.

Now they've unveiled the new project, a mix of one-, two-, three- and four-bedroom apartments across a 30-level building designed by Rothelowman.

[smartcode_project:default project_id=134323 project_image_fid=6384]

The Walden will capitalise on the site’s front-row position on the eastern fringe of the <a href="https://www.apartments.com.au/developments/north-sydney-nsw-2060">North Sydney</a> CBD, which offers uninterrupted Sydney Harbour views stretching from the Sydney Harbour Bridge all the way to Sydney Heads.

The main tower will be flanked by a small four-level amenity building known as The Pavilion, offering exclusive resident-only amenities including a dedicated concierge service, a sauna and private wellness studio, a gymnasium and fitness studio, a resort-style rooftop pool and sundeck.

There will also be a&nbsp;residents’ lounge, private dining and a wine cellar, and co-working facilities with an on-site meeting room and boardroom.

&nbsp;

&nbsp;

[smartcode_project:default project_id=134323 project_image_fid=6382]

ALAND Founder Andrew Hrsto said the company knew they could create something "iconic" with The Walden when they saw the site.

&nbsp;

“As a company, we had been searching for a site in one of Sydney’s blue-chip locations, spanning the Eastern Suburbs, the Sydney CBD and the North Shore, and when we had the opportunity to purchase this site, we immediately recognised that it could be something iconic – being the last development with a view offering this exceptional.

“We identified the attributes and quality of the site as being perfectly aligned for ALAND – and we feel that this off-market acquisition is a perfect opportunity to showcase our craftmanship and expertise through a truly unique offering."

[smartcode_project:default project_id=134323 project_image_fid=6399]

Hrsto pointed to ALAND’s longstanding development expertise as a significant benefit in delivering a positive outcome for The Walden.

“Being a fully integrated development and construction business with a highly experienced team, we have the benefit of in-house experts across the development spectrum, from acquisitions, design, planning, and construction, to sales, marketing, property management, through to building management.

“As one of Australia’s largest private development and construction groups, we’ve been in operation for 23 years, with a Gold Star iCIRT rating and a 100 per cent delivery success rate across numerous masterplanned and mixed-use projects – and we’re very much looking forward to bringing this expertise to The Walden and contributing to the ongoing revitalisation of North Sydney."

The Walden is the latest development in Sydney to have the 10-year Latent Defects Insurance policy by Resilience Insurance, protecting buyers from any structural or waterproofing-related issues for 10 years post-completion.&nbsp;

Demolition of existing structures on The Walden site has already commenced through specialist civil contractor Moits, with the aim of completing preparatory ground works by the end of 2025, ahead of construction commencement in early 2026.

ALAND unveils The Walden, North Sydney's latest luxury apartment development

<a href="https://www.apartments.com.au/developers/toga-group">TOGA</a> has opened sales for the final building in Macquarie Rise, its latest mixed-use development in Macquarie Park.

Since launching its <a href="https://www.apartments.com.au/new-apartments/macquarie-rise-122-herring-road-macquarie-park-nsw-2113">Macquarie Rise</a> in late 2023, TOGA has secured over 125 sales in the Herring Road development, to a range of purchasers, from first home buyers to investors and downsizers. Around 65 per cent of purchasers have been owner-occupiers.

TOGA has now launched a new release of one-, two-, and three-bedroom apartments in the final building, Saunders Rise. Many of the apartments feature multi-purpose rooms and offer views of the surrounding greenery. Also part of the release is a series of&nbsp;sub penthouses housed on the upper floors.

[smartcode_project:default project_id=89243 project_image_fid=242696]

&nbsp;

“We’re delighted with the ongoing strong interest in our Macquarie Rise development, which is testament to the need for premium housing in this much-loved Sydney suburb,"&nbsp;Allan Vidor AM, Managing Director at TOGA, said.

"We’re proud to be able to offer buyers a unique product that includes luxury amenities, spacious living areas and flexible layouts, designed to suit all kinds of buyers, from young professionals to families and investors.

“We have long been advocates of Macquarie Park, and once Macquarie Rise is complete, TOGA will have built 1,000 apartments in the area, delivering much needed homes within a thriving precinct. It’s great to see the area become renowned for high-quality apartments, proximity to amenities and green spaces."

TOGA, one of Australia’s few Gold Star iCIRT rated developers, is also handling construction of Macquarie Rise. They are on track to complete the building in 2027.

[smartcode_project:default project_id=89243 project_image_fid=310789]

Macquarie Rise boasts a prime location, placing residents within immediate reach of Macquarie Centre, Macquarie University, and the newly completed Macquarie University Metro, connecting to the Sydney CBD is just over 20 minutes.

&nbsp;

Macquarie Rise residents also have access to Club Rise, an exclusive, residents only lounge designed by luxury hotel designers Stack Studio, offering an abundance of work and break-out areas, a Pilates studio, a gym, and a karaoke room. As well as these premium amenities Macquarie Rise will also feature an impressive podium top 20m lap pool.

[smartcode_project:default project_id=89243 project_image_fid=242695]

“Offering luxury, spacious apartments in a vibrant and well-connected neighbourhood, it’s no surprise that Macquarie Rise remains popular with a range of buyers," said TOGA's General Manager of Sales, Anthony Falas.&nbsp;

"With interest rates tracking downwards, we expect the final apartments to continue to receive high levels of interest.”

Located at 122 Herring Road, Macquarie Park, the development will be delivered in partnership with Baptist Union NSW and Morling College with a value of over $400 million.

TOGA launches final stage apartments in Macquarie Rise

Flooding

<html><body>
GUEST OBSERVATION
In February, about 600,000 cattle were killed by catastrophic flooding across north Queensland’s Carpentaria Gulf plains.
The flood waters rose suddenly, forming a wall of water up to 70 kilometres wide. Record depths were reached along 500 kilometres of the Flinders River, submerging 25,000 square kilometres of country. Cattle were stranded. Many drowned.
Even though cattleman Harry Batt lost 70% of his herd, he was <a href="https://www.thecourier.com.au/story/5906068/queensland-floods-decimate-native-wildlife/?cs=10229" target="_blank">more concerned about the wildlife</a>. He said, “all the kangaroos, and bloody little marsupial mice and birds, they couldn’t handle it”.
Harry was right to be concerned. As our research, published today in <a href="https://onlinelibrary.wiley.com/doi/10.1111/aec.12803" target="_blank">Austral Ecology</a>, reveals, floods sweeping Australia’s plains have disrupted native species for millions of years. Now, as climate change drives <a href="https://link.springer.com/article/10.1007%2Fs10584-016-1689-y" target="_blank">more intense flooding</a>, we will see this effect intensify.
Flooding causes major disruptions to gene flow
February’s flood came ten years to the day after a <a href="http://www.bom.gov.au/qld/flood/fld_reports/gulf_floods_jan_mar_2009.pdf" target="_blank">far bigger flood</a> on the adjoining river systems that submerged an area larger than Ireland. It was this flood that first drew our attention to the plight of native species.
Noel was asked by <a href="https://mynortherngulf.org/" target="_blank">Northern Gulf Resource Management Group</a> to survey wildlife in areas affected by the 2009 flood. Over the following four years, he found almost no ground-dwelling reptiles, despite them occurring elsewhere in the region. They appeared to have been washed away or drowned.
Biologists have long known that many species’ ranges are interrupted by the <a href="https://www.tandfonline.com/doi/abs/10.1071/MU9870158" target="_blank">Gulf Plains</a>. Hence, these floodplains are considered one of Australia’s most important biogeographic barriers: the Carpentarian Gap.
Many closely related species with a common ancestor are separated by this Gap, including the Golden-shouldered Parrot of Cape York Peninsula and the Hooded Parrot of the Northern Territory. They are thought to have separated around <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1463-6409.2012.00561.x" target="_blank">7 million years ago</a>. 
The Gap also separates many other species, including birds, mammals, reptiles and butterflies, at the subspecies or genetic level. Even more species found on either side are just absent from the Gulf Plains.
<a href="https://images.theconversation.com/files/285075/original/file-20190722-134095-gtpfir.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/285075/original/file-20190722-134095-gtpfir.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a> 
Huge flooding across the Gulf Plains, including the Norman and Flinders Rivers, in February 2009. <a href="https://worldview.earthdata.nasa.gov%20under%20Info/About" target="_blank">NASA Worldview</a>, <a href="http://creativecommons.org/licenses/by-sa/4.0/" target="_blank">CC BY-SA</a>
Flood impacts are immense and under-appreciated
When biologists first tried to find a reason for these patterns, they only considered aridity. They proposed <a href="https://www.tandfonline.com/doi/abs/10.1071/MU9870158" target="_blank">Australia’s arid zone expanded</a> to the Gulf of Carpentaria during ice ages.
There is no evidence for this, but the misunderstanding is completely understandable.
Any dry-season visitor to the Gulf Plains will find a dry, inhospitable environment with few trees or shrubs for shade, cracked clay soils, and lots of flies. European explorers described the region as “God-forsaken”.
But it can be quite a different place in the wet season.
Rains in the Gulf are caused by the summer monsoonal troughs or cyclones. About once a decade, these generate massive downpours. <a href="http://www.bom.gov.au/qld/flood/fld_history/index.shtml" target="_blank">Historical records</a> show at least 14 major floods since 1870.
So, to us, it seemed floods rather than aridity could be the cause of the odd distributions of plants and animals.
We set out to see whether Noel’s findings could have been caused by flooding or whether other factors such as soil, vegetation or climate were more important.
We also wanted to know what other effects floods might have on the region’s ecosystem. Could floods, by eliminating trees and shrubs, be responsible for the hostile appearance of the region? Could ground-dwelling reptiles and birds be underrepresented, not just at Noel’s sites, but on floodplains across the area?
To find out, we divided the area into floodplains and higher-altitude land, and generated 10,000 random sites across the Gulf Plains. We extracted soil, vegetation and rainfall data from national information sources, and examined the patterns.
We found trees and shrubs were significantly less common on floodplains than on land above the flood zone, regardless of soil or rainfall, and tree cover was further reduced on cracking clays. We concluded the plain’s open, hostile appearance is caused by a combination of soils and flooding.
We then examined all gecko, skink and bird records from the <a href="https://www.ala.org.au/" target="_blank">Atlas of Living Australia</a>.
We found ground-living reptiles and birds were much less common on the floodplains, regardless of vegetation or soil. As expected, reptiles were more sensitive to flooding than birds, which can fly to safety during floods.
Finally, we found the sites affected by the 2009 flood had significantly fewer geckos and skinks than other sites across the Gulf Plains.
Increased flooding from climate change could have major consequences
Our findings have evolutionary significance that extends into the future. Repeated disruption of species across their distributions affects gene flow and ultimately produces new species. If <a href="https://link.springer.com/article/10.1007%2Fs10584-016-1689-y" target="_blank">floods become more frequent</a>, as expected under climate change, so might the rates at which new species form.
They also have serious land management implications. Climate change planning emphasises conserving river corridors as safe refuges from arid conditions. However, periodic scouring of many of the nation’s floodplains – expected to increase under climate change – means that this approach needs rethinking.
We conclude that on the most arid occupied continent on Earth, unpredictable floods may cause the most disruption to the Australian plant and animal life.<img src="https://counter.theconversation.com/content/120753/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1">

Catastrophic Queensland floods killed 600,000 cattle and devastated native species

<html><body>
The unprecedented monsoonal event of February 2019 and subsequent floods have led to an upheaval in Townsville market as it undergoes a period of adjustment.
Some property transactions being driven as much by emotional factors as market fundamentals, according to the latest Herron Todd White (HTW) residential report. 
The report noted that the rental market has tightened significantly following this event, with a reported 3,300 properties suffering water inundation of varying levels.
"This displacement of home owners and renters along with the arrival of assessors and builders has resulted in huge demand for rental stock, with vacancy rates falling to a very tight overall trend vacancy of 1% as at April 2019," the valuation firm said.
A three bedroom house located close to the Townsville city centre is currently on the rental market with a price guide of $460 per week.
Set in a slightly elevated position, the house at <a href="https://www.realestate.com.au/property-house-qld-townsville+city-426705010" target="_blank">421A Walker Street </a>(pictured below) comes with three bedrooms, large storage room, living area, open air deck overlooking the pool and private garden area.

Overall, local agents are reporting good levels of interest and sales over the past few months, with anecdotal evidence suggesting some tenants are entering the home owner market following the floods after receiving a payout on contents insurance which provides them the deposit required.
A recent sale was a three bedroom house set on a fully fenced 707 square metre allotment in Condon.
The renovated house at <a href="https://www.realestate.com.au/sold/property-house-qld-condon-131044698" target="_blank">14 South Vickers Road</a> (pictured below) has been sold for $168,000.

It comprises three air-conditioned bedrooms, open plan dining and living area, modern kitchen and covered carport.
"To date the suburbs hardest hit by the flooding have seen limited activity as the rebuilding process continues and therefore the impact on value levels remains undetermined," the valuation firm said.

Huge demand for Townsville rental stock in wake of floods: HTW residential 

<html><body>
Just as the Townsville residential property market appeared cemented in the start of the recovery phase, according to Herron Todd White, floods have hit and perhaps turned that on its head.
After a mining downturn, Townsville has been dealing with heightened levels of unemployment, said the valuer. 
Now, there is some fear the recent flooding will lead not only to a reduction in tourists but economic strength as the clean-up slows down activity.
HTW's latest residential report stated the rental vacancy rate has fallen throughout the year, while there has also been a slight increase in rents in some locations, primarily inner city postcodes.
There is also concern over the rental housing market.
However, the report noted there had not been the ripple effect of the increased activity transfer through to the market in the fringe or outer suburbs. 
It is these fringe and outer suburbs which were hit hardest by the flooding.
In fact, insurers have received more than $100 million in claims so far.
The State Government and Townsville Mayor Jenny Hill have requested insurance companies to use local businesses as much as possible to support the local economy.
Townsville Chamber of Commerce chief executive Marie-Claude Brown said she is concerned industries like retail and hospitality in particular will now take a hit as these businesses can't be supported in the same way a construction/renovation business can.
HTW's report cited major projects such as the Townsville Stadium and Haughton pipeline duplication underway along with a number of projects in the pipeline as reasons for optimism and improving economic conditions.

Has the Townsville housing market taken a hit following the floods?

GUEST OBSERVATION
A flood-ravaged Townsville has captured public attention, highlighting the vulnerability of many of our cities to flooding. The <a href="https://www.propertyobserver.com.au/https://www.abc.net.au/news/2019-02-15/queensland-floods-special-climate-statement/10816184" target="_blank">extraordinary amount of rain</a> is just one aspect of the disaster in Queensland’s third-biggest city. The flooding, increasing urban density, the management of the Ross River Dam, and the difficulties of dealing with byzantine insurance regulations have left the community with many questions about their future.
These questions won’t be resolved until we enhance the resilience of cities and communities against flooding. Adaptation needs to become an integral part of living with the extremes of the Australian environment. I discuss how to design and create resilient urban landscapes later in this article.
Flood risk and insurance
Another issue that affects many households and businesses is the relationship between insurance claims and <a href="https://www.propertyobserver.com.au/https://www.preventionweb.net/news/view/63766" target="_blank">1-in-100-year flood event overlay maps</a>. Projected rises in flood risks under climate change have led to <a href="https://www.theguardian.com/australia-news/2019/feb/20/townsville-homes-may-become-uninsurable-due-to-flooding-from-climate-change" target="_blank">concerns that parts of Townsville and other cities will become “uninsurable”</a> should the costs of cover become prohibitive for property owners.
Council flood data <a href="https://www.propertyobserver.com.au/https://www.preventionweb.net/news/view/63766" target="_blank">used for urban planning and land-use strategies</a> is also used by insurers to assess the flood risk to individual properties. Insurers then price the risk accordingly.
However, in extraordinary circumstances, when the flooded land is actually larger than the area marked by the flood overlay map, complications emerge. In fact, that part of the community living outside the map’s boundaries is considered flood-free. Thus, those pockets of the community may have chosen not to have flood insurance and not have emergency plans, which leaves them even worse off after floods. This is happening in Townsville.
Yet this is nothing new. Many people experienced very similar circumstances in 2011. Flood waters covered as much land as Germany and France combined. Several communities were left on their knees.
Notwithstanding the prompt and vast response of the federal government and Queensland’s state authorities, a few years later Townsville is going through something alarmingly similar.
Adaptation to create resilient cities
To find a solution, we need to rethink how to implement the <a href="https://www.disaster.qld.gov.au/dmg/Prevention/Pages/3-5.aspx" target="_blank">Queensland Emergency Risk Management Framework</a>. That is no easy task. However, it starts with shifting the perspective on what is considered a risk – in this case, a flooding event.
Floods, per se, are not a natural disaster. Floods are part of the natural context of Queensland as can be seen below, for instance, in the <a href="https://www.qhatlas.com.au/content/channel-country" target="_blank">Channel Country</a>.
<a href="https://images.theconversation.com/files/261144/original/file-20190227-150724-xvwvfx.JPG?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/261144/original/file-20190227-150724-xvwvfx.JPG?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
Floods are part of the Australian landscape. Here trees mark the seasonal riverbeds in the Queensland outback between Cloncurry and Mount Isa. Cecilia Bischeri, Author provided
The concept of adaptation as a built-in requirement of living in this environment then becomes pivotal. In designing and developing future-ready cities, we must aim to build resilient communities.
This is the ambitious project I am working on. It involves different figures and expertise with a shared vision and the support of government administrations that are willing to invest in a future beyond their elected term of office.
Ideas for Gold Coast Resilientscape
I live and work in the City of Gold Coast. Water is a fundamental part of the city’s character and beauty. In addition to the ocean, a complex system of waterways shapes a unique urban environment. However, this also exposes the city to a series of challenges, including flooding.
Last September, <a href="https://www.gchaveyoursay.com.au/industryhub/news_feed/updated-flood-overlay-maps" target="_blank">an updated flood overlay map</a> was made available to the community. The map takes into account the projections of a 0.8 metre increase in the sea level and 10% increases in storm tide intensity and rainfall intensity.
These factors are reflected in the 1-in-100-year flood overlay. It shows undoubtedly that the boundaries between land and water are changeable.
Building walls between the city and water as the primary flood protection strategy is not a solution. A rigid border can actually intensify the catastrophe. New Orleans and the <a href="https://soundwaves.usgs.gov/2006/01/" target="_blank">levee failures</a> during the passage of Hurricane Katrina in 2005 provide a stark illustration of this.
Instead, what would happen and what would our cities look like if we designed green and public infrastructures that embody flooding as part of the natural context of our cities and territory?
The current project, titled RESILIENTSCAPE: A Landscape for Gold Coast Urban Resilience, considers the role of architecture in enhancing the resilience of cities and communities against flooding. The proposal, in a nutshell, explores the possibilities that urban landscape design and implementation provide for resilience.
RESILIENTSCAPE focuses on the Nerang River catchment and the Gold Coast Regional Botanic Gardens, in the suburb of Benowa. The river and gardens were adopted as a case study for a broader strategy that aims to promote architectural solutions for a resilient City of Gold Coast. The project investigates the possibility of using existing green pockets along the Nerang River to store and retain excess water during floods.
<a href="https://images.theconversation.com/files/261354/original/file-20190228-150721-xt0v13.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/261354/original/file-20190228-150721-xt0v13.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
Gold Coast Regional Botanic Gardens is one of the green areas along the Nerang River that could be used to store and retain flood water. <a class="source" href="https://commons.wikimedia.org/wiki/File:Gold_Coast_Regional_Botanic_Gardens_(08).jpg" target="_blank">Batsv/Wikimedia Commons</a>, <a class="license" href="http://creativecommons.org/licenses/by-sa/4.0/" target="_blank">CC BY-SA</a>
These green spaces, however, will not just serve as “water tanks”. If mindfully planned, the green spaces can double up as public parks and facilities. This would enrich the community’s social realm and maximise their use and return on investment.
The design of a landscape responsive to flooding can, by improving local urban resilience, dramatically change the impact of these events.
The goal of creating urban areas that are adaptive to an impermanent water landscape is the main driver of the project. <a href="https://www.fastcompany.com/3068730/this-new-orleans-neighborhood-is-fighting-flooding-by-welcoming-it" target="_blank">New Orleans</a> after <a href="https://theconversation.com/disappearing-acts-reflecting-on-new-orleans-10-years-after-katrina-46834" target="_blank">Hurricane Katrina</a> and<a href="https://archpaper.com/2017/10/five-years-sandy-nyc-update-flood-resilience-zoning/" target="_blank"> New York</a> after <a href="https://theconversation.com/frankenstorm-sandy-wreaks-havoc-on-nyc-floods-cities-10420" target="_blank">Sandy</a> are <a href="https://www.nisconsortium.org/nisc-activities/neworleansfloodresexp/" target="_blank">investing heavily in this direction</a> and promoting <a href="http://www.rebuildbydesign.org/" target="_blank">international design competitions</a> and community participation to mould a more resilient future.

Townsville floods show cities that don’t adapt to risks face disaster

<html><body>
Below is an open letter to Australia written by rural real estate agent David Nolan to Prime Minister Mr Morrison (sent directly to him) and Opposition Leader Mr Bill Shorten (sent directly to him).
After what Gillard and Ludwig did in 2011 banning live cattle into Indonesia, you should be pledging billions to this disaster instead of promising to give our money (the tax payers) to the UN.
Leaders of all other Opposition Parties and all the politicians in these political parties and including every bureaucrat the TIME HAS COME !!!
Everyone must unite and get behind those affected by this tragic event in Far North Queensland.
Foreign Aid, Refugees, Boat People and every other overseas hanger on, the party and free hand outs have to stop until this situation is fixed, which may take a number of years.
I apologise to the bleeding hearts regarding the above but what has just happened on our back door is the greatest loss of livestock in a single event in the world's history.
Think about about that long and hard,
A Tsunami of water based on an unprecedented rain fall event which lasted over a week has taken the lives of 300,000 to 500,000 cattle.*
Think about that about long and hard. 300,000 to 500,000* head of cattle. Those numbers are unfathomable.
To put this in perspective so everyone gets an understanding of the magnitude of this disaster, the area covered in water in Far North QLD was the size of Victoria.
Now I ask this question, if Victoria went under water and suddenly there were 300,000 to 500,000* dead cattle lying around, every politician, agri expert etc and the world press would be over it like a rash.
Or is everyone going to say out of sight out of mind. This will be a real test of what sort of Nation we collectively are today.
Now what about the people, AUSTRALIAN FARMERS, our own. What about their health both mental and physical, both now and in the future. The pressure on them must be off the Richter scale.
No income, bank pressure and in some cases not one head of cattle left. Think about it long and hard,
Do these so called leaders of our great country do what all politicians have previously done? Get dressed up in their RM Williams gear with an Akubra Hat, go and visit for a day, kiss a baby, get a photo and then forget all about the people and the problem?
REMEMBER this is the greatest single natural animal disaster to ever happen in history.
These farmers, their families, the employees all loved and cared for these cattle. Think long and hard about them.
We as proud Australians must continue to keep this event from being swept under the carpet. This northern part of QLD is a long way from any major city, but the people and the land is still AUSTRALIAN. So lets never forget that.
So l ask everyone don't stop talking about it and don't stop reminding every politician you can. You can find your local member's contact details <a href="https://websternolanrealestate.cmail20.com/t/j-l-xtkuyhy-jkhhhkdlll-t/" target="_blank" data-auth="NotApplicable">here</a>.
Thank you.
David Nolan a proud Australian with a long bush heritage
It has never happened to so many animals in one event in the history of the world.
*There are forecasts these figures may even significantly increase in the coming weeks.

The horrendous Far North Queensland weather event of February 2019: David Nolan

<html><body>
<img src="https://counter.theconversation.edu.au/content/68170/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1">
GUEST OBSERVER
Recent floods in New South Wales, South Australia and Victoria have reminded us of the power of our weather and rivers to wreak havoc on homes, business and even, tragically, lives. 
As Dorothea Mackellar poetically pointed out, “droughts and flooding rains” have been a feature of Australia throughout history, so maybe we shouldn’t be all that surprised when they happen.
However, we also know that the reported costs of flooding in Australia have been increasing, most likely through a combination of increased reporting, increased exposure through land use change and population growth, and changes to flood magnitude and severity. So it is critical that we understand what might be causing these changes.
This was the question we asked in our review on how flood impacts have changed over time in Australia and how they may change in the future. We found that despite decades of research in these areas, there are still many gaps in what we know.
<h2>Copping a soaking</h2>
We know that floods depend not just on how much rain falls, but also on how wet the ground is before a heavy rainfall, and how full the rivers are. We also have evidence that the storms that generate heavy rainfall will become more intense in the future, because as the atmosphere warms it can hold more moisture. 
This is particularly the case for storms that last just a few hours; in fact we think that these storms are the most likely to show the largest increases. In urban environments this translates to an even greater flood risk, because the concrete and hard surfaces allow this intense rain to run off quickly through storm drains and into creeks and rivers, rather than seeping into the landscape.
In larger catchments and rural areas the story is more complicated than in cities. If the soil is very wet as a result of rain over the previous weeks and months, then when a big storm hits there will be a lot of runoff. In contrast, if the soil is dry then flooding is less likely to be a problem. 
Engineers currently use simple models to estimate this relationship between soil wetness and storm rainfall. But our research indicates that these simple models will need to be replaced with longer-term simulations that model all of the previous rainfall leading up to the storm. 
Simple models use simple assumptions to translate rainfall risk into flood risk. But if these assumptions are incorrect, our estimates of flood risk (that is, the probability of a given flood magnitude occurring in any particular year) could be wrong. Flood risk is used to guide infrastructure assessment through cost-benefit ratios, so getting it right is important.
One of the reasons that catchment wetness varies is because of climate cycles like El Niño and La Niña. We have some idea how these and similar ocean cycles affect our climate, including the fact that they can cause fluctations in flood risk over decades-long timescales. 
The difficulty here is that for most locations we only have 50 to 60 years of recorded river flow data. This makes it hard to separate out the influences of these climate cycles from other trends in flood data, such as the effect of increasing urbanisation. 
There has been progressively less monitoring of streamflow in Australia over the past few decades, and this makes it even harder to understand regional changes in flood risk. Governments need to prioritise investment in data collection to allow us to improve our estimates of the risk of flooding and the associated damages now and in the future. 
The recent work by the Bureau of Meteorology to develop a comprehensive set of high quality streamflow gauge data is a step in the right direction, but much more investment is needed in these areas.
Finally, we recommend that continued research into the fundamental changes likely from climate change is required. This requires climate models to be run at a range of resolutions to enable all the important climate processes for extreme rainfall to be properly represented. 
Recent pressure on CSIRO’s climate modelling capabilities is concerning – the scientific questions are by no means fully answered on these topics. It is great to see the recent funding of the ARC Centre of Excellence on Climate Extremes. The work of these researchers, combined with ongoing efforts across Australia, will be important to provide better assessments on climate changes. This can help engineers and hydrologists continue to provide accurate flood risk estimates.
