A who's who of Australian surfing, business and entertainment has emerged on title records following the completion of Esprit Rainbow Bay, the latest boutique beachfront apartment development by former professional surfer Paul Gedoun's S&amp;S Projects.

The completed project has attracted an enviable collection of owners, many with long-standing ties to the southern Gold Coast and the surf culture that has helped define Rainbow Bay and neighbouring Kirra for generations.

Given Gedoun's own background in surfing, it perhaps comes as little surprise that some of Australia's most recognisable surfers have chosen to buy into the development overlooking one of the country's most celebrated stretches of coastline.

Pezet Matheson directors Jayde Pezet and Todd Matheson launched the project in late 2021, and have managed the sales campaign all the way through to its sell-out and recent completion.

Former world champion Mick Fanning, who grew up in Coolangatta, secured an apartment in 2023. He paid&nbsp;$2.07 million. Last year he sold his Bilinga home for over $16 million.

Three-time world champion Joel Parkinson also purchased in the development, alongside big wave surfer Mark Mathews. Mathews bought the most expensive apartment in the building, spending just over $4 million.

Joining them is Rip Curl founder Doug Warbrick, whose company helped shape Australia's global surfing industry over the past five decades.

The appeal of Rainbow Bay has extended well beyond the surfing community.

International DJ Paul Fisher purchased an apartment through his investment vehicle, YLB Developments, an abbreviation of his trademark phrase "You Little Beauty".

The purchase comes as Fisher and his wife Chloe are developing their own luxury apartment project further north in Palm Beach. Their boutique beachfront development, Pescado, comprises just seven apartments on Jefferson Lane, which start from just shy of $6 million. The couple intend to retain the two-level penthouse as their Australian base between international touring commitments.

Melbourne Storm coach Craig Bellamy and his wife Wendy have also invested in Esprit, purchasing two apartments after spending decades holidaying on the southern Gold Coast. They also have a luxury apartment in Joe Adsett's Rockpool, less than 400m away from Esprit.

<h2>Boutique project draws owner-occupiers</h2>

Esprit launched in 2021 and sold strongly, with buyers drawn to its boutique scale, beachfront position and contemporary design.

The completed development comprises 94 apartments across 11 levels, offering expansive floorplans designed primarily for owner-occupiers rather than the investor market.

Crowning the building is Club Esprit, pitched as being the Gold Coast's first residential rooftop wellness centre. The roof features a&nbsp;25 metre magnesium lap pool, which is surrounded by wet daybeds and poolside cabanas,&nbsp;multiple barbecue areas,&nbsp;a yoga and relaxation play lawn, and a private dining room with a kitchen scullery, bar, lounges, and an outdoor terrace.

The wellness centre is&nbsp;fully equipped with a Technogym, ice bath, infra-red sauna, steam room, thermal room, and treatment room. The roof has views spanning&nbsp;Rainbow Bay, Snapper Rocks and the Pacific Ocean.

<h2>S&amp;S Projects continues to shape Rainbow Bay</h2>

S&amp;S Projects founder Paul Gedoun has become one of the key figures behind Rainbow Bay's evolution over the past several years.

After establishing S&amp;S Projects, Gedoun has focused on delivering lifestyle-driven apartment developments designed primarily for owner-occupiers seeking a permanent coastal home.

Esprit is Gedoun's third completed project in Rainbow Bay, following Flow and Awaken, both of which achieved record prices for the suburb.

He is now delivering <a href="https://www.apartments.com.au/new-apartments/radia-rainbow-bay-271-boundary-street-coolangatta-qld-4225">Radia Rainbow Bay</a>, a 38-apartment development on Boundary Street that is currently selling, and has no plans to leave the precinct anytime soon. S&amp;S Projects has also lodged plans for its fifth Rainbow Bay development, an 88-apartment project on Boundary Street featuring a strong wellness focus.

Nature Based Cities (NBC), the not-for-profit organisation focused on improving biodiversity and nature outcomes in urban development, has launched its latest industry design guidelines and accreditation framework, this time targeting precinct-scale residential communities.

The move extends NBC’s influence beyond its initial focus on medium and high-density residential developments. Several projects have already achieved NBC accreditation since the launch of its Medium &amp; High-Density Residential Guidelines in early 2025.

The expansion into masterplanned communities and new residential precincts reflects the growing need for stronger nature-positive benchmarks as Australia’s outer suburban growth corridors continue to expand at pace.

Paul Hameister OAM, NBC Founder and the Executive Chairman of Melbourne developer Hamton who itself leans heavily into nature and biodiversity in its developments, says the&nbsp;nature-first approach to mitigate the effects of climate change has become standard in other parts of the world such as the UK, but Australia is lagging.&nbsp;Australia’s environmentally sustainable design (ESD) rating tools have no minimum mandatory requirements for living landscapes.

“We’ve always wanted to do more, and we know other developers who want to do more, but the ESD rating tools just aren’t there,” Hameister says. “In Australia, you can have a five-green-star rated building that’s concrete and glass with not a blade of grass. 
 
“The focus is on reducing emissions, which is laudable, but there hasn’t been enough attention paid to protecting and re-establishing nature. We need both for the health of the environment and for communities.”

He says that having now&nbsp;made good progress in supporting developers of medium and high-density residential projects, NBC is now looking to bolster better nature-based decision-making and recognise developers of greenfield projects in the outer ring and large inner-ring brownfield precincts, who want to champion nature and living landscape as a defining feature.

Since 2022, the not-for-profit has sought to remove the roadblocks preventing developers from incorporating nature and living landscapes into their projects, shifting the conversation from the reduction of emissions and grey infrastructure, toward recognising nature as an essential infrastructure.

The New Communities Design Guidelines and Scorecard arm developers with the tools needed to deliver a nature positive outcome for their new communities. Intended to be adopted at the outset of the planning process, the guidelines are designed to help create communities that are cooler, healthier and more resilient while also enhancing social wellbeing and long-term economic value.&nbsp;

New Communities developers seeking accreditation will be independently assessed across a range of key criteria including ecology, tree canopy, biodiversity, and walkability. Once the masterplan is complete and submitted for approval, the scorecard is formalised based on proposed outcomes. Projects that meet the NBC criteria will receive either Commended or Exemplary accreditation outcomes, creating a clear benchmark for nature-positive new communities in Australia.&nbsp;

Janis Fischer, Director at Tract and NBC Advisory Council member, said the development of new communities in our suburbs can have a substantial impact on nature and biodiversity.

"By incorporating nature-based design principles at the inception of a project, developers and their design teams can achieve nature positive outcomes that are good for both people and the planet.’’&nbsp;

NBC accredited New Community projects will gain access to NBC branding and marketing tools to help communicate their nature-based credentials to purchasers and the broader market.&nbsp;

Nature Based Cities: A new Australian benchmark for developing nature-positive new communities

Apartment buildings are increasingly being designed around how people actually live day to day, not just how they want a building to look.

For buyers, that shift is showing up in practical inclusions that respond to changing habits. Work-from-home spaces, EV charging, wellness amenities, secure bike storage and parcel management are becoming part of the broader apartment conversation, reflecting a move toward buildings that reduce friction in everyday life.

Online shopping has become one of the clearest examples of that change.

Australians spent a record $82.6 billion online in 2025, with nearly one in four retail dollars now spent online. That has made parcel delivery a regular part of apartment living, rather than an occasional inconvenience.

For apartment residents, however, the delivery process can be less straightforward than it is for detached homes. Parcels may be left in lobbies, redirected to Post Offices, missed entirely, or placed under the responsibility of building managers and concierge teams.

That is why secure parcel infrastructure is increasingly being considered alongside more familiar apartment amenities.

<iframe allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen="" frameborder="0" height="315" referrerpolicy="strict-origin-when-cross-origin" src="https://www.youtube.com/embed/-VjjLwoViX0?si=A3k7ws9NX35Uac7_" title="YouTube video player" width="560"></iframe>

Australia Post Parcel Lockers offer one way to address the issue. When a parcel arrives, residents receive a notification through the AusPost app or SMS, then collect it using a QR code or one-time PIN. The parcel is kept secure, accessible and removed from common areas.

The broader Parcel Locker network now includes more than 1,500 locations across Australia, positioned at Post Offices, shopping centres, supermarkets, transport hubs and other accessible locations.

For new apartment projects, the relevance is clear. A building’s amenity offering is no longer only about lifestyle spaces, but also about convenience, security and functionality.

As buyer expectations evolve, secure parcel delivery is becoming part of the same design conversation as flexible working, sustainable transport and resident wellbeing.

It is one less thing for residents to worry about, and another example of apartment design adapting to the way Australians now live.

Apartment design is adapting to the way Australians shop

While school holidays and trips to Europe tend to define the winter property market, there's been no cold snap at <a href="https://www.apartments.com.au/new-apartments/the-walden-north-sydney-177-walker-street-north-sydney-nsw-2060">The Walden</a> in North Sydney.

Developer-builder&nbsp;<a href="https://www.apartments.com.au/developers/aland">ALAND</a> sold more than $35 million worth of apartments throughout June, including a $6.8 million apartment that now ranks among the highest apartment sales ever recorded in North Sydney.

SRM Residential agent Ben Stewart said buyer demand throughout June reflected a mix of improving market confidence and longer-term thinking from owner-occupiers.

"We're seeing strong demand from owner-occupiers who are taking a longer-term view," Stewart said.

"Many recognise the opportunity to secure an apartment in an iconic building and premium location while values remain attractive. They may initially lease the property, but the intention is to eventually move in themselves, rather than purchasing purely as an investment."

[smartcode_project:default project_id=134323 project_image_fid=367129]

Located at 177 Walker Street, The Walden will deliver 161 one, two, three and four-bedroom residences across a 30-storey tower designed by Rothelowman. Every apartment occupies a corner position, maximising natural light, cross ventilation and views across Sydney Harbour, the Opera House, Sydney Heads and the northern districts.

Rather than a traditional balcony, the residences feature winter gardens that seamlessly extend the open plan living areas, creating versatile spaces for relaxing or entertaining throughout the year. Floor-to-ceiling glazing draws in natural light while showcasing sweeping views from the building's elevated Walker Street position.

Every apartment features high-end Calacatta marble, bespoke joinery, and fully integrated appliances.

The larger residences have been planned with distinct entertaining and private zones, with many master suites positioned on corners to capture natural light and harbour views. Walk-in dressing rooms, freestanding baths and refined stone finishes reinforce the house-like feel that has resonated with downsizers and owner-occupiers.

[smartcode_project:default project_id=134323 project_image_fid=6393]

Rothelowman Principal Ben Pomroy said the project was designed to make the most of its unique position overlooking the harbour.

"The Walden is a celebration of all things beautiful, curated for those who expect nothing less than exceptional," Pomroy says.

"Meticulously designed entertaining spaces and light-filled living areas that capitalise on capturing the natural beauty of Sydney's iconic harbour."

Residents will also have exclusive access to The Pavilion, a dedicated amenity building featuring a rooftop pool, wellness studio, gymnasium, sauna, concierge service, residents' lounge, private dining spaces and work-from-home facilities.

[smartcode_project:default project_id=134323 project_image_fid=6402]

The project marks ALAND's first major luxury apartment development in Sydney's inner-city market after more than two decades delivering residential communities across Greater Sydney.

Founder and CEO Andrew Hrsto previously said the rarity of the Walker Street site made it an opportunity the company could not overlook.

"This is a rare opportunity to bring a truly exceptional project to life in one of Sydney's most iconic locations, and to showcase our craftsmanship and design expertise at a world-class level," Hrsto said.

[smartcode_project:default project_id=134323 project_image_fid=6383]

The Walden has been introduced to the market at a time when demand for living in North Sydney is at an all-time high. Billions of dollars have been invested in infrastructure, including the recently opened Victoria Cross Metro station, located just 300 metres from The Walden, providing residents with direct access to the Sydney CBD in just minutes.

Private investment has also transformed the area through the arrival of new retail and dining destinations, elevating the lifestyle offering in what was once considered primarily a commercial precinct rather than an aspirational residential address.

The Walden is currently under construction and is scheduled for completion in 2028.

ALAND records $35 million in sales in North Sydney as The Walden bucks quiet winter selling season

The long-awaited redevelopment of the former Eastlakes Shopping Centre site has reached a major milestone, with Conquest's plans for a new mixed-use precinct officially placed on public exhibition.

The State Significant Development Application would transform the 1.7-hectare site at <a href="https://www.apartments.com.au/new-apartments/19a-evans-avenue-eastlakes-nsw-2018">19A Evans Avenue</a> into one of Sydney's largest urban renewal projects, delivering 736 apartments above a new shopping centre anchored by Woolworths, alongside specialty retail, dining, commercial space and new public open spaces.

The public exhibition marks the next chapter for the project after <a href="https://www.apartments.com.au/developers/conquest">Conquest</a> acquired the stalled Stage Two development from Crown Group, who completed the first stage across the road prior to their voluntary liquidation.

<img alt="First look: Conquest unveils plans for 736-home Eastlakes Shopping Centre redevelopment" data-entity-type="file" data-entity-uuid="5fca22c5-d1ed-4e2c-8801-03f7df1eafc8" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/eastland%20podium.png?VersionId=uomwr41nF8CmLUZRDcu3mHQechlbxucS" />

&nbsp;

Designed by DKO Architecture, the proposal comprises four residential buildings ranging from 14 to 18 storeys above a two-level retail podium. The development would deliver 736 apartments, including 74 affordable homes, 215 Build-to-Rent apartments and 521 market residences. Provision has also been made for dual-key apartments, which could increase the total number of dwellings to 877.

At ground level, the shopping centre has been designed as the suburb's new meeting place, anchored by a full-line Woolworths and complemented by a curated mix of fresh food retailers, cafés, restaurants, health services and everyday convenience shopping. Generous pedestrian links and landscaped public spaces will connect the retail precinct through to Jack Mundey Reserve, creating a more walkable and connected neighbourhood.

Conquest CEO Michael Akkawi said the redevelopment was about far more than replacing a shopping centre.

"Eastlakes has been overlooked for too long, and this is the community’s moment. We are building a shopping centre and homes, a genuine heart for the suburb, and we genuinely want locals to help shape it."

"We enrich communities through the creation of homes, places, and experiences designed for life, built to last, and owner for generations. That starts with listening, so we warmly encourage everyone with a connection to Eastlakes to view the plans and share their thoughts."

DKO said the design had been shaped by the site's landscape setting and surrounding open space.

"Our vision for the site embraces its unique Bidjigal identity by blending the residential living with generous landscaping and a material palette inspired by the Bidjigal locality, and celebrating the panoramic views to Botany Bay and the wetlands reserves."

"Taking cues from Country, we seek to harmonise built form with the landscape and lightly touch the earth. By reconnecting, retaining and regenerating existing ecology, and weaving in natural elements, we can deepen our connection to Country."

The landscape strategy extends across the podium and rooftops, incorporating communal gardens, children's play areas, lawns, community gardens, family gathering spaces and extensive tree planting. New landscaped links will also strengthen the connection between the precinct and Jack Mundey Reserve, while publicly accessible open spaces have been integrated throughout the development.

The proposal builds on Conquest's broader placemaking strategy for the site. Through an ongoing partnership, local artist Joe Rashbrook has been appointed Urban Art Curator, working alongside young residents to transform the project's site hoardings into a public art gallery that allows the community to engage with the redevelopment before construction is complete.

Conquest has rapidly expanded its development pipeline since acquiring the Eastlakes site, with more than $6 billion worth of mixed-use projects now in planning across Sydney, including Stanmore, Castlecrag and Waterloo.

Conquest CEO Michael Akkawi said the redevelopment was about far more than replacing a shopping centre.

Native Birds

<html><body>
GUSET OBSERVATION
Glossy Black-Cockatoos used to be common on South Australia’s Kangaroo Island until possums started eating their eggs and chicks. After volunteers helped protect nest hollows and erect safe nest boxes, the population more than doubled.
But how do you measure such success? How do you compare cockatoo nest protection with any other investment in conservation?
Unfortunately, we have few ways to compare and track the different efforts many people may be making to help conserve our natural treasures.
That’s why a group of us from a dozen Australian universities along with scientists and private researchers around the world have created <a href="https://onlinelibrary.wiley.com/doi/10.1111/cobi.13220">metrics of progress</a> for both our understanding of how to manage threats of different intensity, and how well that management has been implemented. We also provide guidance on what still needs doing before a threat no longer needs active management.
For the first time, we looked at every threatened bird in Australia to see how well – or not – they are managed. Hopefully, we can use this to avoid compounding our disastrous <a href="https://www.theguardian.com/environment/2018/feb/13/a-national-disgrace-australias-extinction-crisis-is-unfolding-in-plain-sight">recent track record</a> of extinctions in Australia.
The state of Australian birds
What we did differently was collect the same data across different species, which meant we could compare conservation efforts across all bids.
<a href="https://images.theconversation.com/files/246799/original/file-20181122-182062-zfg4ry.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/246799/original/file-20181122-182062-zfg4ry.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" alt=""></a>
The mallee emu-wren is unique to Australia and endangered due to habitat loss. <a class="source" href="https://www.flickr.com/photos/128578170@N06/24288853338/in/photolist-D1jHTq-4b9JJc" target="_blank">Nik Borrow/Flickr</a>
When we applied these metrics to Australia’s 238 threatened bird species, the results were both encouraging and daunting. The good news is that we understand how to reduce the impact of about 52% of the threats – although of course that means we know little about how to deal with the other 48%.
But the situation is decidedly worse when we consider how effectively we are putting that research into practice. Only 43% of threats are being managed in any way at all – and just a third of the worst threats – and we are achieving good outcomes for just 20%.
But at least we now know where we are. We can celebrate what we have accomplished, appreciate how much needs doing, and direct our efforts where they will have the greatest benefit.
The threats to our birds
Introduced mammals, particularly <a href="https://www.sciencedirect.com/science/article/abs/pii/S0006320717302719" target="_blank">cats</a>, have been (and continue to be) a significant threat to Australian birds. Although we have successfully eradicated feral animals on many islands, saving many species, they remain a grave threat on the mainland.
The effect of climate change is becoming the top priority threat for the future. About half of all threatened birds are likely to be affected by increases in drought, fire, heat or sea level. Given the policy prevarication at a global level, targeted research is essential if birds are to be helped to cope.
By looking at multiple species, we can also identify what helps successful conservation. <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/emr.12335" target="_blank">Monitoring</a>, for instance, has a big impact on threat alleviation – better monitored species receive more attention.
There is also – unsurprisingly – a strong connection between knowledge of how to manage a threat and successful application of that knowledge. Often policy people want instant action, but our work suggests that action before knowledge will squander money.
Where to from here?
So what can we use this analysis for? One use is helping species <a href="http://www.nespthreatenedspecies.edu.au/news/no-surprises-no-regrets-identifying-australias-most-imperilled-animal-species" target="_blank">close to extinction</a>.
Using the same approach for multiple species groups, it is apparent that, while birds and mammals are in a parlous state, the most threatened fish are far worse off. We can also identify some clear priorities for action.
Finally, we must acknowledge this work emerged not from a government research grant, but from a non-government organisation (NGO). BirdLife Australia needed an overview of the country’s performance with threatened birds and was able to draw on the volunteered skills of biologists and mathematicians from around the country, and then the world.
Indeed, one of the future projects will be using the new assessment tool to see just how much of the conservation action around the country is being driven by volunteers, from the many people who contributed their knowledge and skills to this paper through to those keeping glossy black-cockatoo chicks safe on Kangaroo Island.<img src="https://counter.theconversation.com/content/107432/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;">

For the first time we’ve looked at every threatened bird in Australia side-by-side

<html><body>
GUEST OBSERVER
The fourth <a href="https://aussiebirdcount.org.au/" target="_blank">Aussie Backyard Bird Count</a> has just ended, with nearly 2 million birds from 635 species submitted to the BirdLife Australia app. The count, which is in its fourth year, has created a national database of birds found in our backyards.
We don’t know yet exactly how many people participated this year, but more than 60,000 people submitted checklists in 2016. Participants span the whole country, though participation is highest in our urban areas. By surveying our backyards (rather than “good” bird spots), these citizen scientists provide ecologists – like me – with information from urban areas we would not otherwise sample.
This includes data on a range of common bird species that are not frequently analysed because these species are believed to be secure. One of the most surprising results is a decline in the frequency of occurrence of the laughing kookaburra across southeast Australia.
Counting birds
Everyone has a bird story – and fortunately for ecologists, everyone is willing to share them. With 85% of Australia’s population living in cities and towns, birds are an important connection to our natural environment.
<a href="https://images.theconversation.com/files/192541/original/file-20171031-18711-13owlfd.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/192541/original/file-20171031-18711-13owlfd.PNG?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" alt=""></a>

But birds are also <a href="https://www.bioone.org/doi/abs/10.2326/osj.9.3?journalCode=jorn" target="_blank">good environmental indices</a>. They’re generally easy to measure, they respond quickly to environmental change and we know a reasonable amount about the ecology of most species.
Between 1998 and 2014, BirdLife Australia volunteers collected a significant amount of data. This was used to develop a terrestrial bird index in 2015 – a bird “Dow Jones” to track our biodiversity. It was here that the decline in kookaburras was first identified.
The data were drawn from BirdLife Australia’s ongoing atlas project, now called <a href="https://birdata.birdlife.org.au/" target="_blank">Birdata</a>. However, there are biases in this data set, as people obviously like to go birdwatching where they will see more birds. This may inflate the frequency of encountering some species and decrease the chances of encountering others – particularly rare and cryptic species.
For the last four years, we’ve asked volunteers to add to this data by counting birds around their home for a week in October, when many birds are highly active and visible. These counts complement the data already available in Birdata by allowing access to backyards across Australia, which are generally poorly represented in the larger data set.
While there are still limitations in the Backyard Bird Count data, such as the risk of mis-identification, for common species like the laughing kookaburra we can generally be confident that the identification is correct. Even if the same bird is counted multiple times, our models report only a species’ presence or absence, so inflated numbers don’t affect the trend.
Are kookaburras really declining?
The below figures show modelled trends for the kookaburra across metropolitan Melbourne and Sydney. These figures are derived from the volunteer-collected Birdata, much of which comes from green spaces and remnant vegetation in these landscapes.
I wondered whether these declines are true changes in the populations, or reflect a change in the way kookaburras are using the landscape, possibly moving into the matrix of urban backyards that just don’t get surveyed. Looking solely at the backyard count data, I found similar trends in the reporting rates of kookaburras as those in the models, supporting that this decline is at the population level. What started out in 2014 as a way of engaging the broader community with their birds is now collecting useful ecological data.
Further exploration of the ABBC data across other capital cities found some interesting things. In both Perth and Hobart, where the kookaburra is considered an introduced species, the birds are recorded more frequently than in Melbourne and across the ACT. In Perth, increases in 2016 compared to previous years suggest an increase in the species there.
<a href="https://images.theconversation.com/files/192539/original/file-20171031-18700-ecicwi.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/192539/original/file-20171031-18700-ecicwi.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>

The figure on the left is for Melbourne, and on the right is for Sydney. The reporting rate shows the percentage of surveys where kookaburras were recorded as present. The thick black line is the modelled trend (with confidence intervals in dashed line), the pink line shows the statistically significant linear trend, the thin black line shows the monthly calculated reporting rate, and the green spots show acceleration (or a favourable change) in the trend. Note that due to modelling method, the ends of figures tend to blow out as there is no data from which to predict trend.
While three years does not make a trend, Aussie Backyard Bird Count data from heavily urbanised areas suggest we are seeing a decline in this iconic species in the eastern capitals. Likely reasons for this are the loss of nesting hollows and possibly reductions in the availability of prey as we increasingly modify our urban landscapes. We don’t really know as this is not an area that has been researched.
We need citizen scientists
Collecting enough data (especially from the backyards of towns and cities) to detect these kinds of changes can be an overwhelming task. This is where citizen science programs like the Aussie Backyard Bird Count can help.
As well as helping ecologists track large-scale biodiversity trends, it also gives people the chance to connect with their natural environment and gain a greater appreciation of our unique fauna.
As with all citizen science projects, there are limitations in the data being collected. However, the Backyard Bird app has been designed to make counting as simple and standardised as possible, providing confidence in the tally of common and “iconic” species, and filling in the gaps found in other data sets.
The good old kookaburra is neither rare or cryptic. If anything, if people are seeking out “good” bird habitat to survey we would expect that kookaburras would be one of those species subject to inflated reporting. But this is not what we encountered.

Once all the data from the Aussie Backyard Bird Count have been collated and vetted we will continue to explore the developing trends in Australia’s urban birds. Increasing engagement and awareness in our communities can help ensure our backyard birds are still around to count next year.

Life in the city can be stressful – for birds just as much as people. For humans, cities are expressly designed to put roofs over heads and food within easy reach, but the opposite can be true for many urban birds. They can find food and shelter harder to come by in the concrete jungle – with some notable exceptions.
For any species in any habitat, survival is about problem-solving and adapting to the environment. So what street smarts do city birds need? And why do some species, such as lorikeets, crows and ravens, seem to dominate our urban landscapes?
In general, urban birds must be bolder than those that remain in natural habitats, as can be seen by the boldness (or “habituation”) with which some species will forage for food with people nearby. But they also need to be able to avoid or retreat from unfamiliar objects or situations if they seem dangerous.
City birds also need to withstand exposure to a wide range of pathogens. A study of birds in Barbados found that urban birds have enhanced immune systems relative to their country counterparts.
While we have changed the environment in which some birds live, reducing resources in terms of food and shelter and increasing the number of pathogens that may impact their health, some birds have largely benefited from the new way of life.
<h2>Winners and losers</h2>
Within the urban ecosystem, there are winners and losers in the bird world. The suburban landscape, for example, now provides more nectar from flowers than native vegetation due to the gardens that people have established. This is a big help to nectar-feeding parrots such as Rainbow Lorikeets.
A recent study in Sydney found that the lorikeets benefit from the increased abundance of flowers in urban areas, and their numbers were higher in the leafy suburbs than in bushland.
But if urban areas are such a rich source of nectar, why are some nectar-feeding species declining?
The Regent Honeyeater feeds mainly on nectar and other plant sugars. It has been seen in orchards and urban gardens, but is listed as critically endangered by the federal government.
This is partly because widespread clearance of woodland habitat has led to the increase of the aggressive Noisy Miner and Red Wattlebird. These species find it easy to “bully” other birds in open habitats. Noisy Miners have been observed pulling apart Regent Honeyeaters' nests as they were being built.
Regent Honeyeaters, in contrast, are less adaptable to changed landscapes, because they are migratory and rely on detailed knowledge of existing food sources. If these resources are changed or removed, they may not have enough interconnected patches of habitat to move safely towards new resources – potentially leaving them vulnerable to cats, foxes and aggression from other birds.
Habitat loss can threaten some bird species or even leave them at risk of dying out if they do not locate alternative resources. The ability to find new food sources therefore becomes a valuable survival skill.
<h2>What’s more useful: flexibility or intelligence?</h2>
For some bird species, flexibility in finding food is crucial in making a successful switch to urban environments. One example is the Grey-crowned Babbler, which is endangered in Victoria, but my colleagues and I have documented it living in a suburban area in Dubbo, New South Wales.
This species usually nests in coniferous woodland and forages in the leaf litter beneath the trees. But in Dubbo, we saw these birds feeding on lawns, in playgrounds and even in leaf litter along a train track at the back of urban housing, sometimes visiting backyards along the way. This suggests that these birds can survive the loss of their woodland habitat by being sufficiently adaptable to life in the suburbs – as long as they can continue to find enough food, disperse between nearby groups and have access to native nesting trees.
For other species, such as crows and ravens, intelligence seems to be the key. These species can survive anywhere in the urban sprawl, including places where trees are scarce but rubbish bins are everywhere. Crows and ravens can literally pull food out of a bin and eat it – clearly a learned behaviour that has resulted from problem-solving.
These birds are highly opportunistic and social, allowing them to learn new ways of adapting to the almost complete removal of their natural environment.
<h2>Survive and thrive</h2>
What we can deduce from these examples is that some birds, like Rainbow Lorikeets and Grey-crowned Babblers, can adapt successfully to the urban sprawl as long as some characteristics of their habitat still remain. Other species, such as crows, have gone a step further and worked out how to survive purely on urban resources – effectively making a living in an environment that is completely unnatural to them.
This suggests that the more we urbanise an area without natural aspects, the less bird diversity we will have – and the more our urban areas will come to be dominated by those few species that are hardy, clever or adaptable enough to thrive.
Luckily, some councils in Australia and cities throughout the world are bringing the natural aspects of the forest back into the concrete jungle, so that a wider range of birds might survive here. More research is needed to work out exactly what each species will need, but planting more native plants is always a good start.

Blocks and flocks: why are some bird species so successful in cities?

<html><body>
GEUST OBSERVER
Some Australian birds are pushing out other species, and even damaging trees. Noisy and bell miners are two of Australia’s most aggressive bird species. Found throughout eastern Australia, in recent years their numbers have increased at the expense of our smaller birds.
Both myna species are spreading to new areas, largely due to human destruction of habitat. Noisy miners are able to invade areas where habitat has been modified, particularly gardens.
Bell miners, meanwhile, can invade areas that have invasions of weeds in the understorey such as blackberry and lantana that they use for nesting.
The good news is we can help stop the spread of these birds, by putting native plants in our gardens.
<h2>Good birds gone bad</h2>
Both species of these miners (genus Manorina) have been found to reduce bird diversity through their aggressive behaviour, and have been associated with eucalypt dieback.
Human disturbance has been linked to increasing numbers of noisy miners. One study in the box-ironbark forests of southeast Australia, found that noisy miners an move into areas of smaller fragments and unhealthy trees.
They then chase away other birds, reducing the number of species and potentially having knock-on effects on ecosystems. The problem is so serious that noisy miners are listed as a national threatening process.
More research is needed to find out why bell miners are becoming more common. But our research has found that bell miners show similar behaviour to noisy miners. They have a distinctive call that travels for tens of metres through the forest.
Bell miners cause Bell Miner Associated Dieback in trees. It is thought that their feeding and breeding behaviours lead to the death of eucalypts on the east coast of Australia. They also take over habitat that would be used by other birds.
<h2>Are the birds to blame?</h2>
Where miners are normally found in lower numbers, disturbances by people can tip the balance in their favour. This includes increasing noise levels, removing corridors of connecting native vegetation, creating gardens with exotic plants, building cities, houses, parks, logging and introducing invasive species that create thick understories.
These disturbances increase the habitat available for these two species, allowing them to increase in number and drive out the smaller birds that compete for their food sources.
Noisy miners particularly favour open areas that don’t have thickets of shrubs of smaller trees underneath the canopy. Conversely, bell miners prefer thick understoreys, particularly those create by introduced weeds such as lantana.
So if we are causing these birds to increase in number, how can we reduce their numbers and re-create the original habitat where all species could co-exist?
<h2>Build a bird-friendly garden</h2>
You need to create a multi-layered habitat of ground covers, small and medium shrubs, and trees that provide food and shelter locations all year for a variety of species.
These plant species need to have diverse structures, and should be close together to form dense, protective thickets, including climbers within medium-to-tall shrubs and trees, nectar-bearing and seed-bearing plants. Mulch can also encourage insect life for insectivorous birds.
Plants should also be local species that grow naturally in the area and are suited to the climate. Native birds that live in the area will then visit your garden as another food source in their territory.
Reducing weeds in your garden and neighbouring bushland (many weeds are derived from garden plants) can help native species. General natives can also be planted if you can’t find local natives in your local nursery.
Even in gardens where noisy miners dominate, smaller birds can survive in a dense understorey.
Meanwhile, a thin midstorey with fewer leaves may help to reduce bell miner abundance, as suggested by our recent study near Kyogle, New South Wales.
You should also consider the timing of flower and fruit production, to ensure that there is always food available for birds. You should also remove fruiting plants such as cotoneaster and blackberry that attract predators such as currawongs, to help reduce predation on smaller bird species.
Using chemical-free weed and pest control and mulching garden waste can also increase the food available for birds.
Lawns can also be replaced with native grasses that produce seed to attract finches and other seed-eaters such as crimson rosellas. Birds also need fresh water, which you can provide with a pond or bird bath. This should be placed within vegetation to ensure birds feel safe from predators.
<h2>Why are native gardens important?</h2>
Local biodiversity can be maintained by native gardens, ensuring long-term ecological sustainability. Small birds and other wildlife benefit from planting native species.
Many species are negatively affected by the current structure of gardens such as lawns, few scattered trees and the placement of concrete and houses without any access to nesting habitat.
Gardening in Australia needs to be changed to favour more native species and provide structure on a landscape scale that includes a variety of gardens.
