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.

Southern Cross Station anchors the western end of <a href="https://www.apartments.com.au/developments/melbourne-vic-3000">Melbourne</a>’s CBD, connecting metropolitan and regional rail with tram and bus interchanges in one of the city’s busiest transport corridors.&nbsp;

Just metres away, <a href="https://www.apartments.com.au/new-apartments/640-bourke-street-melbourne-640-bourke-street-melbourne-vic-3000">640 Bourke Street</a>&nbsp;will place residents in the heart of the city, with immediate access to Spencer Street trams, a growing mix of retail, hospitality and cultural venues, and a neighbourhood evolving into a lively residential precinct.

Developed by <a href="https://www.apartments.com.au/developers/far-east-consortium">Far East Consortium</a>, the 68-level project integrates a sculptural glass tower with the heritage-listed Eliza Tinsley Building on a 2,765 sqm Bourke St site.&nbsp;

[smartcode_project:default project_id=509 project_image_fid=335425]

Designed by <a href="https://www.apartments.com.au/architects/rothelowman">Rothelowman</a>, the development replaces a previously approved scheme for 813 apartments with a refined offering of just over 600 larger-format residences, responding to a growing owner-occupier demand for spacious city living.

The location sits within a dynamic pocket undergoing significant transformation. Marvel Stadium and the Docklands waterfront are less than 10 minutes away on foot, offering both sports and leisure attractions.&nbsp;

Bourke Street Mall, Queen Victoria Market, and the State Library are all within walking distance, while Flagstaff Gardens, Melbourne’s oldest park, provides a green escape just to the north.

&nbsp;

[smartcode_project:default project_id=509 project_image_fid=335422]

Proximity to some of the city’s largest employers and education hubs, including the courts precinct, legal chambers, RMIT, and major hospitals, makes 640 Bourke Street an appealing residential address for professionals, families and students alike.

Education opportunities span all levels. Nearby, Haileybury City Campus offers private schooling just a short walk from 640 Bourke Street. Just beyond the CBD fringe, Carlton Gardens Primary School, one of Melbourne’s oldest state primary schools, and Docklands Primary School provide convenient government schooling options.

Higher education is equally accessible. RMIT University’s city campus spans multiple buildings just a few blocks away, while the University of Melbourne’s Parkville campus is easily reached via tram along Swanston or Elizabeth Streets.

Victoria University’s City Queen campus, focused on law and business, is also close by, positioning 640 Bourke Street within walking distance of three of Melbourne’s major tertiary institutions.

[smartcode_project:default project_id=509 project_image_fid=335426]

The neighbourhood’s retail tapestry continues to evolve into something distinctly local and walkable. Just steps away, Woolworths Metro on Bourke Street ensures that everyday essentials are easily within reach.&nbsp;

For larger shopping trips, Spencer Outlet Centre on Spencer Street and QV Melbourne on the opposite side of the CBD broaden the offering with supermarkets, fashion, dining and specialty stores.

The lane-to-lane vibe unfolds beautifully in nearby arcades and alleys. Hardware Lane, with its European-style red-brick paving and alfresco dining, pulses with jazzy evenings and casual lunches.

A few minutes north, Howey Place and Centre Place offer leafy, boutique-lined lanes where hidden cafés and niche retailers congregate under historic glass-covered cloisters.

Completing this tapestry is the newly opened Mecca “beauty playground” on Bourke Street. Spanning 4,000 sqm over three levels, the flagship blends immersive retail within an art-deco heritage setting.

&nbsp;

[smartcode_project:default project_id=509 project_image_fid=335427]

This finely grained network of shops, eateries, arcades and service outlets defines the everyday lifestyle at 640 Bourke Street - further enriched by over 3,000 sqm of resident amenity including a Turkish-inspired pool, gym, co-working rooms and private cinemas.&nbsp;

Apartments are priced between&nbsp;$640,000 and $3.95 million. Off the plan stamp duty concessions available until October 2026. Prospective buyers can visit the on site display gallery which has&nbsp;fully built one, two, and three-bedroom apartments.

Lower North Shore development specialists&nbsp;<a href="https://www.apartments.com.au/developers/abadeen-group">Abadeen</a>&nbsp;has topped out its new local apartment development,&nbsp;<a href="https://www.apartments.com.au/new-apartments/northcote-collective-naremburn-2-6-northcote-street-naremburn-nsw-2065">Northcote Collective</a>.&nbsp;

Located in the tightly held suburb of <a href="https://www.apartments.com.au/developments/naremburn-nsw-2065">Naremburn</a>, Northcote Collective is a collection of just 58 one-, two-, and three-bedroom apartments designed by award-winning architects Rothelowman.&nbsp;

The building is just a five to 10 minute walk from the heart of Crows Nest and the new&nbsp;St Leonards and Crows Nest Metro stations. Abadeen has also brought doorstep convenience, with a ground-floor retail offering on Northcote Street.

Northcote Collective is being delivered by&nbsp;<a href="https://www.apartments.com.au/builders/decode">Decode</a> — an iCIRT-rated construction company well regarded in the new development industry.

[smartcode_project:default project_id=114189 project_image_fid=272840]

“This is an important and exciting moment for Northcote Collective, and we’re proud to celebrate this milestone with our partners, consultants, and future residents,” said Justin Brown, Executive Chairman and Founder of Abadeen.&nbsp;

“From the outset, our vision was to create something truly special for Naremburn — homes that respect the character of the neighbourhood while elevating the standard of Lower North Shore living. With connectivity to transport, retail on the doorstep and a true village lifestyle, this milestone also comes at a perfect time when buyer confidence is returning to the market. I am incredibly proud of our team and of Decode for their dedication in helping us bring this vision to life.”

[smartcode_project:default project_id=114189 project_image_fid=272865]

The development is two-tiered, with two rooftops for residents. The taller building has an impressive rooftop pool, a rare inclusion in the new Sydney apartment market. The level, with panoramic views, also includes an entertaining terrace with barbecue facilities.

Local downsizers and young professionals are showing the strongest interest in the development, with recent improvements in the property market — supported by three rate cuts in 2025 — boosting borrowing power and buyer confidence.

Auction activity across Sydney surged by almost 30 per cent in recent weeks, with clearance rates above 70 per cent — signalling a renewed wave of buyer demand.

Northcote Collective will welcome buyers in 2026.

Sunshine Coast-based <a href="https://www.apartments.com.au/developers/devcon-property-group">Devcon Property Group</a> has acquired one of Maroochydore’s most prominent development sites for $12 million unlocking the potentialfor a mixed-use project in the Cotton Tree precinct.

&nbsp;

The 4,178 sqm site at 41–43 Aerodrome Road—well known locally as the former home to one of Australia’s last Sizzler restaurants—was sold via an off-market expressions of interest campaign by Colliers agents Nick Dowling and Baydn Dodds. More than 70 targeted buyer groups were approached, resulting in multiple competitive offers for the property.

Devcon Property Group Managing Director Michael Kain said the acquisition was a strategic move in line with the company’s focus on delivering high-quality projects in prime coastal locations.&nbsp;

“We’re excited about the possibilities this site, in one of the Sunshine Coast’s most iconic beachside &nbsp;communities, offers for a broad range of development outcomes,” Kain said.

“Its location, ocean view potential, and proximity to the Maroochydore CBD and beach make it an &nbsp;outstanding development prospect. Our plans are to refurbish the existing building and then review &nbsp;development options for the remainder of the site.”&nbsp;

<img alt="Aerodrome Rd site overlooking Beach (Large)" data-entity-type="file" data-entity-uuid="a29dc4ed-68c1-4bec-a4fc-283063dcde1e" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Aerodrome%20Rd%20site%20overlooking%20Beach%20%28Large%29.jpg?VersionId=b0WxJWevmLoAfCP4YvGImZpR3rSCJJ9L" />

Colliers Special Projects Manager Baydn Dodds said the sale reflected the ongoing strength of the &nbsp;Sunshine Coast’s development site market, particularly for projects capable of achieving water views. &nbsp;

“Sites of this scale, in walkable beachside locations with ocean views, are tightly held and continue to attract significant interest from both local and national developers,” Baydn Dodds said. &nbsp;

“Holding a prominent position as the former home to one of Australia’s last Sizzler restaurants and more recently occupied by Rashays, the prime site is located just 150 metres from Maroochydore Beach.&nbsp;

“With stunning ocean view potential, located in one of the Sunshine Coast’s best known iconic &nbsp;beachside communities, within steps of shops, cafes and the beach it is no surprise that there was strong interest in the site. The transaction highlights the ongoing depth of demand for well-located &nbsp;mixed-use sites across the Sunshine Coast.”&nbsp;

Colliers Sunshine Coast Managing Director Nick Dowling said the transaction reinforced the &nbsp;Sunshine Coast’s status as one of Australia’s most active development markets.&nbsp;

“The combination of strong population growth, lifestyle appeal, and infrastructure investment is &nbsp;driving demand for quality development opportunities,” Nick Dowling said. &nbsp;

“The Sunshine Coast is one of only three markets nationally to record an increase in crane numbers, &nbsp;reflecting the strength of the region’s construction pipeline.&nbsp;

“Opportunities like this are rare and continue to generate strong buyer interest in the region.”&nbsp;

The Sunshine Coast development market is booming, with several high-profile developers like Cube Developments, Gardner Vaughan Group, and RCQ, planning developments in the region.

GUEST OBSERVATION
I was in Switzerland recently and discovered that they haven’t had any landfill since the early 2000s, because all of their waste is either recycled or incinerated to produce electricity. How “green” is it to incinerate waste in order to produce electricity? Is it something New Zealand should consider, so that 1) we have no more landfill, and 2) we can replace our fossil-fuel power stations with power stations that incinerate waste?
Burning rubbish to generate electricity or heat sounds great: you get rid of all your waste and also get seemingly “sustainable” energy. What could be better?
Many developed countries already have significant “waste-to-energy” incineration plants and therefore less material going to landfill (although the ash has to be landfilled). These plants often have recycling industries attached to them, so that only non-recyclables end up in the furnace. If it is this good, why the opposition?
Here are seven reasons why caution is needed when considering waste-to-energy incineration plants.
Stifling innovation and waste reduction
<ol>
<li>Waste-to-energy plants require a high-volume, <a href="http://www.seas.columbia.edu/earth/wtert/sofos/Rodriguez_thesis.pdf" target="_blank">guaranteed waste stream</a> for about 25 years to make them economically viable. If waste-to-energy companies divert large amounts of waste away from landfills, they need to somehow get more waste to maintain their expensive plants. For example, <a href="https://www.thelocal.se/20181112/sweden-imports-british-waste-to-heat-homes-but-wheres-the-post-brexit-solution" target="_blank">Sweden imports its waste from the UK</a> to feed its “beasts”.</li>
<li>The waste materials that are easiest to source and have buyers for recycling - like paper and plastic - also produce most energy when burned.</li>
<li>Waste-to-energy <a href="http://knowledgeauckland.org.nz/assets/publications/TR2019-009-CBA-on-waste-diversion-from-landfill-homes-land-community-Auckland.pdf">destroys innovation</a> in the waste sector. As a result of China not accepting our mixed plastics, people are now combining plastics with asphalt to make roads last longer and are making fence posts that could be replacing treated pine posts (which emit copper, chrome and arsenic into the ground). If a convenient waste-to-energy plant had been available, none of this would have happened.</li>
<li>Waste-to-energy <a href="http://knowledgeauckland.org.nz/assets/publications/TR2019-009-CBA-on-waste-diversion-from-landfill-homes-land-community-Auckland.pdf" target="_blank">reduces jobs</a>. Every job created in the incineration industry removes six jobs in landfill, 36 jobs in recycling and 296 jobs in the reuse industry.</li>
<li>Waste-to-energy works against a circular economy, which tries to keep goods in circulation. Instead, it perpetuates our current make-use-dispose mentality.</li>
<li>Waste-to-energy only makes marginal sense in economies that produce coal-fired electricity – and then only as a stop-gap measure until cleaner energy is available. New Zealand has a green electricity generation system, with about 86% already coming from renewable sources and a <a href="https://www.beehive.govt.nz/release/nz-embracing-renewable-electricity-future" target="_blank">target of 100% renewable by 2035</a>, so waste-to-energy would make it a less renewable energy economy.</li>
<li>Lastly, burning waste and contaminated plastics creates a greater environmental impact than burning the equivalent oil they are made from. These impacts include the release of harmful substances like dioxins and vinyl chloride as well as mixtures of many other harmful substances used in making plastics, which are not present in oil.</li>
</ol>
Landfills as mines of the future
European countries were driven to waste-to-energy as a result of a <a href="https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32006L0012" target="_blank">2007 directive that imposed heavy penalties</a> for countries that did not divert waste from landfills. The easiest way for those countries to comply was to install waste-to-energy plants, which meant their landfill waste dropped dramatically.
New Zealand does not have these sorts of directives and is in a better position to work towards reducing, reusing and recycling end-of-life materials, rather than sending them to an incinerator to recover some of the energy used to make them.
Is New Zealand significantly worse than Europe in managing waste? About a decade ago, a delegation from Switzerland visited New Zealand Ministry for the Environment officials to compare progress in each of the waste streams. Both parties were surprised to learn that they had managed to divert roughly the same amount of waste from landfill through different routes.
This shows that it is important New Zealand doesn’t blindly follow the route other countries have used and hope for the same results. Such is the case for waste-to-energy.
There is also an argument to be made for current landfills. Modern, sanitary landfills seal hazardous materials and waste stored over the last 50 years presents future possibilities of landfill mining.
Many <a href="https://www.reuters.com/article/us-environment-waste/tracking-europes-waste-theres-gold-in-them-landfills-idUSKBN1F61YH" target="_blank">landfills have higher concentrations of precious metals</a>, particularly gold, than mines and some are being mined for those metals. As resources become scarcer and prices increase, our landfills may become the mines of the future.<img src="https://counter.theconversation.com/content/128630/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;">

Climate explained: seven reasons to be wary of waste-to-energy proposals

GUEST OBSERVER
Australia is a land of extreme weather. Events such as the 2009 Victorian bushfires, the 2011 Queensland floods and Cyclone Yasi in 2013 are stark examples of climate-related risks faced by Australian households. Many homes are built in high-risk locations including floodplains, coastlines and bushfire-prone land.
The Climate Institute has released a report detailing the critical role Australian housing plays in the economy, and the risks housing faces with a changing climate.
It also sets out the role of banks and insurers in promoting risk reduction and climate adaptation for Australian housing.
<h2>Built on sand</h2>
Housing represents many Australians' biggest financial commitment – including those who rent rather than buy. Housing accounts for up to one-third of the economy, through direct and indirect means and across sectors such as finance, insurance and construction. With population projections forecasting continued growth and attraction to risky locations, banks and other financial institutions have a crucial role to play in minimising the economic threat posed by climate change.
But while the role of land-use planning and insurance with regard to climate risks has been well documented, the role of banks as gatekeepers to housing finance has been largely overlooked.
As the Climate Institute’s report points out, banks have a “unique ability and incentive” to steer housing purchases, because they are the main providers of residential financing. As such, they have large financial liabilities if homes are lost to fires, floods or other climate effects.
There are a range of tactics banks might use to reduce or mitigate climate risk. For instance, they could favour lending on homes that meet specific risk-reduction requirements, such as raised floor levels for homes in flood zones, or fireproof construction materials in bushfire-prone regions. This approach could also be used in setting mortgage insurance premiums as well as the mortgages themselves. Another approach is to better apportion their exposure - by lending on a reduced percentage threshold of the total property value.
Westpac has a Climate Change Position Statement and both the Commonwealth Bank and NAB have committed in reducing carbon. But more needs to be done for housing.
If banks continue under a business as usual approach, they face the risk that many properties will be devalued over time, through continued exposure to extreme weather events. This represents a significant financial liability, especially when you consider that a home loan typically takes 30 years to play out – a similar time scale to the many climate impacts expected for Australia.
Banks are already making moves to restrict lending based on location.
But the report outlines several other things banks could do, such as:
<ul>
<li>
examine climate risk exposure in their current lending practices
</li>
<li>
use their role as financiers to support good policy, by engaging policymakers and financial regulators
</li>
<li>
encourage stakeholders, including the public, private sector and civil society sectors, to develop ways to minimise climate impact risks for housing
</li>
<li>
ensure losses are addressed in an equitable way.
</li>
</ul>
<h2>A climate insurance policy</h2>
The report also details how the insurance sector assesses risk to housing, and how it might improve its approach in the future, given the intersection of urbanisation, population trends and the trend towards living in climate-threatened areas.
The insurance sector has historically been seen as the messenger of housing market signals, because of its keen focus on assessing weather-related risk. But the 2011 Queensland floods highlighted many weaknesses in relying on insurance alone.
Many properties did not have adequate flood insurance, leaving many people without a home after losing their house to the floods. The Australian and Queensland governments and the private sector struggled to co-ordinate a cost-effective response, partly because of previous bad land-use planning decisions, but also because of the lack of adequate insurance cover.
A federal government levy helped the affected regions to “build better back”. Some chose to rebuild in the same high-risk locations.
Critically, gaps identified in building codes, land use and climate resilience still require a more co-ordinated response. The current Stage 2 coastal law reforms in New South Wales offer a potential example of how competing interests might be balanced.
At face value, this issue is a no-brainer. After all, risk mitigation is bread and butter for lending institutions and insurers, and we already know that extreme weather events are forecast to increase in frequency and severity. National resilience is required.
Quantifying this risk will be easier if financial institutions utilise access to relevant data on issues like coastal risk. Some of these data are becoming more freely available. Recognising the value of climate data is a trend that should continue. For a robust and resilient future, governments and the private sector should end their tango over who should pay for the information and agree that financial climate risks are best faced with eyes wide open.

GUEST OBSERVERS
Australia’s snow season is notoriously fickle. Some years bring deep cover lasting for nearly six months (such as in 1964). Others barely cover the grass for a few weeks (such as in 2006).
The difference between a good season and a bad one may be a single weather event, such as the so-called Snowmageddon in 2014, which dropped around a metre of snow in less than a week.
The high variability of the snow season means the Bureau of Meteorology doesn’t currently produce a seasonal outlook for snow (as we do for temperature and rainfall). However, we know that the same climate drivers that affect Australia’s weather also influence our snowfall.
<h2>El Niño and La Niña</h2>
The best way to see how snowfall varies from year to year is to use data from Spencers Creek in the New South Wales Snowy Mountains, a pristine site 1,830 metres above sea level. Past studies show that these data tend to correlate with snow more generally across the mainland alpine regions, but they don’t always match the cover at lower elevations.
First, let’s look at El Niño. We are coming out of one of the strongest El Niño events on record. During El Niño years, rainfall is typically below average across eastern Australia during the snow season, and temperatures are warmer during the day. The maximum snow depth averages about 35cm less than the all-years average, while the period with more than 100cm is about two weeks shorter.
El Niño’s opposite, La Niña, usually brings above-average rainfall, but this doesn’t necessarily mean more snow. Temperatures can sometimes be too high and hence precipitation may fall as rain even at higher elevations, which can actually decrease snow depths.
This has happened more frequently in recent decades as a result of climate change. Seven of the past eight La Niña years have produced lower maximum snow depths than average.
Historically, neutral years have had more consistent good snow depths than either El Niño or La Niña years.
It is important to consider these drivers as tilting the odds towards a particular outcome, rather than guaranteeing it. While about half the historical El Niño years have had well-below-average snow, three El Niño years had well-above-average snow depths: 1972, 1977 and 1991. That said, no recent El Niño year has produced good snow, with these winters tending to be particularly dry.

<h2>The other players</h2>
To make things more complicated, El Niño and La Niña don’t act alone.
The Indian Ocean Dipole (IOD) may actually be a clearer indicator of snow depth. Similarly to El Niño, positive IOD years tend to be drier than average across southeastern and central Australia, leading to lower snow depths. They are particularly dry over the Australian Alps when El Niño and positive IOD events coincide.
Unsurprisingly, snow depths in late winter and spring are also lower when the IOD is positive. Snow depths are generally higher than average during years with a negative IOD.
The Southern Annular Mode (SAM) has the strongest relationship with snowfall. Cold fronts and low pressure systems are the main weather systems that bring our snow, and the SAM indicates whether the westerlies that bring this weather are closer to Australia or the poles.
Negative SAM brings the fronts, rain and snow further north, while during a positive SAM these fronts move further south. The average (mean) maximum snow depth in negative SAM years is a cool 240cm, almost 80cm higher than in positive years. Unfortunately, accurate forecasts for SAM are still only possible for two to three weeks ahead, which means that this measure is more of a diagnostic rather than a forecasting tool.
Of course, climate change also plays a role. Both maximum snow depth and total snow accumulation have declined over the past 25 years. The reduction in snow cover is most obvious at lower elevations and at the end of the ski season when warm spring rains can hasten the melt.
However, while it has been a few decades since the last 3-metre year (in 1992), there are still above-average seasons when the weather and climate is right, most recently in 2012.

<h2>Less moisture? Never fear, snowmaking is here</h2>
El Niño, positive IOD and positive SAM periods all typically lead to less moisture in the air, which partly explains the lower snowfalls. But with less cloud to trap in the heat at night, they also have lower minimum temperatures.
Luckily for snowriders, these are also the ingredients for good snowmaking and can contribute to less snow melting. The ability to harvest snow and move it where needed can also allow ski resorts to moderate the impacts of average or below-average natural snow cover on skiers and snowboarders.
<h2>What’s ahead in 2016?</h2>
While forecasts for the Southern Annular Mode only have skill for a few weeks ahead, and it’s also too early to forecast what may happen in the Indian Ocean, we can look to the Pacific.
The 2015 El Niño is in decline and neutral conditions are expected to prevail by winter. For 2016, the most likely outcomes are either neutral or La Niña conditions, a hopeful early sign for 2016 snowfalls.
Finally, a word of caution. Don’t get too excited by early snowfalls, or indeed sell your skis if winter starts with no cover: two of the best seasons on record – 1956 and 1981 – had no snow at all at the start of June, while two of the poorest seasons – 2006 and 1965 – had 20cm and 60cm, respectively, of snow on the ground before the Queen’s Birthday weekend. Early-season cover isn’t always the guide we might think it is.
While we know the Australian snow season can certainly have large variations in its snow cover, knowing the state of Australia’s climate drivers can give a heads-up on what the season may be like. But remember, there are always exceptions to the rules.
