For most new apartment buildings, the Owners Corporation starts life with little more than a bank account and the first quarterly strata levies.

At <a href="https://www.apartments.com.au/buildings/9-gay-street-castle-hill-9-gay-street-castle-hill-nsw-2154">9 Gay Street</a> in <a href="https://www.apartments.com.au/developments/castle-hill-nsw-2154">Castle Hill</a>, it starts with around $7 million in reserve.

It's an unusual legacy of what was once one of Sydney's highest-profile apartment remediation projects. When the development, originally known as Skyview and built by disgraced developer Top Place, came under scrutiny by then NSW Building Commissioner David Chandler, an $11 million remediation bond was negotiated to ensure any building defects could be fully rectified.

The building underwent an 18-month remediation program, during which around $4 million of that bond was spent bringing the building up to the standard it should have been in from the outset.

After extensive inspections, all active rectification orders have been lifted. What's more, around $7.2 million remains secured for the Owners Corporation for the next 15 years.

In a twist few would have predicted, what began as a significant concern for purchasers has left the building with something almost unheard of in the apartment market: a multi-million-dollar financial reserve from day one.

<a href="https://www.apartments.com.au/project-marketer/equitifund-group">Equitifund</a> Executive Chairman Greg Huxley said the structure offers buyers a level of certainty that is difficult to replicate.

"The $11 million bond established for the Skyview Castle Hill development represents exceptional value, providing genuine financial security for purchasers," Huxley said.

"Unlike a standard insurance policy, this bond consists of real funds held in trust for the Owners Corporation, offering a tangible layer of protection and added peace of mind."

The apartments themselves have been designed with a focus on practical, contemporary living. Interiors feature Smeg appliances, stone benchtops, tiled living areas, carpeted bedrooms, 2.7-metre ceilings, floor-to-ceiling glazing, and ducted heating and cooling throughout.

Residents also have access to a range of shared amenities, including two rooftop barbecue areas, a swimming pool, children's playgrounds, secure building access, storage cages, and visitor parking.

The location continues to be one of the project's strongest drawcards. Castle Hill Metro Station sits virtually on the doorstep, providing direct connections across Sydney's expanding Metro network, while Castle Towers offers extensive retail, dining, entertainment, and service amenities within walking distance.

[smartcode_project:default project_id=147685 project_image_fid=359127]

The building, now named after its location at 9 Gay Street, comprises a diverse mix of one-, two-, and three-bedroom apartments starting from just under $600,000.

Equitifund National Sales Director Ben Hamblett said demand in the Hills District continues to be driven by buyers seeking convenience and connectivity.

"Interest from both owner-occupiers and investors in Castle Hill remains exceptionally strong, with buyers consistently prioritising developments in close proximity to the Metro station and Castle Towers Shopping Centre," Hamblett said.

"There is a clear trend in the market, with purchasers seeking convenient access to transport and lifestyle amenities that support a seamless, low-maintenance way of living."

On top of the long-term protection afforded by the remaining $7.2 million bond, Equitifund is offering a limited-time stamp duty rebate on selected apartments.

Eligible purchasers can also secure finance options, including a 3.99 per cent two-year variable rate, loan-to-value ratios of up to 90 per cent, and interest-only lending options through EquitiCredit.

Why this Castle Hill apartment building starts with a $7 million advantage

For much of the past few years, conversations about Australia's property market have centred on the rapid growth seen in Sydney, Brisbane, Gold Coast, and Perth. <a href="https://www.apartments.com.au/developments/melbourne-vic-3004">Melbourne</a> has followed a different trajectory.

That relative underperformance is now encouraging some buyers to reassess the city, particularly those willing to look beyond short-term market movements and focus on quality property in established locations, along with the long-term growth prospects of a city expected to overtake Sydney as Australia’s most populous.

John Bekiaris, Research &amp; Market Insights at <a href="https://www.apartments.com.au/project-marketer/equitifund-group">Projects by Equitifund</a>, said Melbourne's current position is attracting increasingly sophisticated purchasers.

"Melbourne continues to present one of Australia's strongest long-term investment stories," Bekiaris says.

"While other capital cities have experienced stronger recent growth, that relative underperformance is exactly what's attracting sophisticated counter-cyclical investors."

[smartcode_project:default project_id=1979 project_image_fid=363268]

Equitifund isn't just commenting on Melbourne's property market, it's investing in it.

The Sydney-headquartered capital partner has taken over the remaining apartments at <a href="https://www.apartments.com.au/buildings/victoriana-melbourne-20-queens-road-melbourne-vic-3004">Victoriana</a>, the recently completed glass-encased development opposite Albert Park Lake in Melbourne's tightly held St Kilda Road precinct.

Designed by <a href="https://www.apartments.com.au/architects/rothelowman">Rothelowman</a> and built by <a href="https://www.apartments.com.au/builders/hickory">Hickory</a>, Victoriana places residents between one of Melbourne's most recognised parklands and the CBD, offering oversized two and three-bedroom apartments aimed at owner-occupiers seeking a genuine alternative to a traditional family home.

The development comprises 232 completed residences alongside a suite of resident amenities, including a 25-metre indoor swimming pool, gymnasium, landscaped entertaining areas, resident lounges, EV charging, secure basement parking and a concierge-style arrival experience.

[smartcode_project:default project_id=1979 project_image_fid=363229]

The apartments have been designed with owner-occupiers firmly in mind.&nbsp;Open-plan living and dining areas flow onto generous balconies framing views across Albert Park Lake, Fawkner Park, the Royal Botanic Gardens and the Melbourne skyline.

Kitchens feature Gaggenau appliances, stone benchtops and generous preparation space. Bedrooms include built-in robes, while bathrooms feature full-height textured tiling. Hardwood flooring and ducted air conditioning complete residences designed for long-term living.

Rothelowman's architecture takes its cues from the landscape opposite the site. Sweeping horizontal glazing references the movement of Albert Park Lake, while generous balconies and expansive glazing strengthen the connection between the apartments and the surrounding parklands. The result is a building designed to deliver the scale and amenity expected of luxury apartment living, while offering the larger floorplans increasingly sought by owner-occupiers.

[smartcode_project:default project_id=1979 project_image_fid=363284]

The location is one of Victoriana's defining characteristics. Positioned on Queens Road, residents are directly opposite Albert Park Lake and within easy reach of Fawkner Park, the Royal Botanic Gardens, South Melbourne, St Kilda Road and the CBD. With few comparable development opportunities remaining in the precinct, buyers are increasingly placing value on outlooks that are unlikely to be interrupted by future construction.

Greg Huxley, Founder of Equitifund, believes those qualities become even more valuable over time.

"Premium real estate has always rewarded buyers who take a long-term view," Huxley said.

"Victoriana represents the kind of asset that's increasingly difficult to recreate today, particularly in an established location like Queens Road."

He said rising construction costs are also changing the way buyers assess completed developments.

"When you combine an irreplaceable location with thoughtful architecture and premium finishes, you create something that becomes increasingly difficult to reproduce as construction costs continue to rise."

[smartcode_project:default project_id=1979 project_image_fid=363228]

According to National Sales Director Ben Hamblett, enquiry has been driven largely by Melbourne downsizers and buyers upgrading from smaller apartments.

"Interest in Victoriana continues to build, with strong buyer focus on the larger owner-occupier residences within the development," Hamblett says.

"Enquiry is increasingly driven by local buyers who recognise the rarity of what's on offer: park-facing apartments in an established neighbourhood where new development opportunities are becoming increasingly scarce. At Victoriana, the view is not just a feature; it's an appreciating asset in its own right."

He said interstate enquiry has also strengthened as buyers reassess Melbourne's position within the national property cycle.

"Melbourne currently stands as the most compelling entry point of any major Australian capital, and discerning buyers are beginning to recognise what those who move early always understand: the best opportunities are taken before the price rise confirms them."

Why now is the time to buy in Melbourne's premium apartment market

Developers and apartment buyers have a narrowing window of opportunity before Brisbane's Olympic infrastructure pipeline begins competing directly with residential construction, pushing up costs, tightening labour supply and making new projects increasingly difficult to deliver.

While Brisbane's apartment market continues to benefit from strong population growth and limited housing supply, industry research suggests the years leading up to 2027 could prove to be the most important period for developers looking to secure builders and buyers hoping to purchase before the next wave of price increases.

A new Colliers report, Brisbane 2032 Olympic and Paralympic Games: Creating Solutions, highlights the scale of the challenge. While thousands of new homes are planned across South East Queensland, the Brisbane Olympic Athletes Village alone will deliver more than 10,500 beds during the Games before being converted into around 1,750 to 2,000 apartments. Equivalent to almost two years of typical inner-city apartment supply, the project will also absorb a significant share of the construction workforce and building materials.

The broader construction pipeline paints an even clearer picture.

Construction Skills Queensland's Horizon 2032 report forecasts Queensland's annual construction pipeline will average $69 billion over the coming years before peaking at $75 billion in 2027-28. Demand for construction workers is expected to increase by 17 per cent to almost 150,000 people, with the industry facing an annual shortfall of around 19,000 workers that could blow out to as many as 35,000 during the peak construction period.

The Olympic venues, athletes village and supporting infrastructure will account for billions of dollars worth of work across South East Queensland through to 2032, creating intense competition for labour at a time when Australia's residential construction sector is already under pressure.

[smartcode_project:default project_id=150489 project_image_fid=373834]

Colliers Queensland Residential Director Andrew Scriven said the convergence of these projects is creating a clear window of opportunity for both developers and buyers.

"From 2027 onwards, the market will shift dramatically," Scriven said.

"Labour will increasingly be locked into government-led infrastructure and Olympic projects, which means private residential developments will face higher costs and tighter margins. The developers who move now are the ones most likely to get projects off the ground."

Scriven said the same dynamic would also affect buyers, with fewer apartment projects expected to launch once construction capacity tightens.

"If you're looking to change your lifestyle over the next five years, now is your window of opportunity to buy."

[smartcode_project:default project_id=150713 project_image_fid=373827]

Developers are already positioning themselves ahead of that window.

Following the success of Monarch at Toowong, Consolidated Properties is preparing to launch two new Brisbane apartment projects in the second half of 2026. They include <a href="https://www.apartments.com.au/new-apartments/gloriette-30-bedivere-street-yeerongpilly-qld-4105">Gloriette</a> at Yeerongpilly Green, a 25-storey tower within one of Brisbane's key Olympic precincts, and <a href="https://www.apartments.com.au/new-apartments/castile-47-skyring-terrace-newstead-qld-4006">Castile</a>, a recently approved 25-storey riverfront development at 47 Skyring Terrace in Newstead.

Hutchinson Builders will deliver both projects, with early works already underway at Yeerongpilly and Newstead expected to commence later this year.

The timing comes as Brisbane's fundamentals continue to strengthen, with strong interstate migration, population growth and vacancy rates remaining below 1.5 per cent.

Colliers Queensland researcher Pragya Sharma said Greater Brisbane is forecast to require around 40,000 new apartments between 2021 and 2031.

"There's a real mismatch emerging between when housing is needed and when it will be feasible to build," Sharma said.

"As a result, the period leading up to 2027 presents a key window of opportunity for developers to secure approvals, funding and construction capacity, while buyers will have greater choice before supply constraints intensify."

Colliers research outlines a critical pre-2027 window to start residential projects before labour squeeze: now is the time to buy

Developers, buyers on watch in South East Queensland ahead of construction crunch: Colliers

It's taken less than nine months for developer Sherpa Property Group to sell out all 51 apartments in its <a href="https://www.apartments.com.au/new-apartments/flourish-oasis-palm-beach-7-9-sixth-avenue-palm-beach-qld-4221">Flourish Oasis</a> development in <a href="https://www.apartments.com.au/developments/palm-beach-qld-4221">Palm Beach</a>, over a year before its anticipated completion.

&nbsp;

Located at 7-9 Sixth Avenue, the $67 million development has resonated strongly with both local owner-occupiers and downsizers seeking high-quality apartments within walking distance of the beach, dining precincts and everyday amenities.

[smartcode_project:default project_id=151449 project_image_fid=357458]

Christie Leet, Founder of <a href="https://www.apartments.com.au/developers/sherpa-property-group">Sherpa Group</a>, said the sell-out reflected both the strength of the Palm Beach market and the success of Sherpa's community-first approach to development.

"The sell-out of Oasis is a fantastic outcome and reinforces the strong demand we're seeing for thoughtfully designed apartments in lifestyle locations," Leet said.

"From the outset, our vision was to create a development that genuinely enhanced the Palm Beach community while providing residents with exceptional homes and wellness-focused amenities.

"We've been incredibly encouraged by the level of local support throughout the campaign, 72.5 per cent of buyers are locals, with a significant proportion of purchasers choosing Oasis as their future home rather than an investment."

[smartcode_project:default project_id=151449 project_image_fid=357463]

Construction is now progressing following development approval, with trusted builder LPS Group delivering the project and completion anticipated in Q3 2027.

Oasis forms part of Sherpa Group's successful Flourish collection, which has become recognised for its focus on wellness, community and elevated coastal living.

[smartcode_project:default project_id=151449 project_image_fid=357469]

Residents will have private access to a rooftop amenity space featuring a pool, gym, sauna, steam room, hot and cold plunge pools, spa and barbecue facilities.

"The success of Oasis demonstrates that buyers continue to prioritise quality, location and lifestyle," Leet said.

"We are proud to have delivered a project that has resonated so strongly with the market and look forward to bringing Oasis to life for our future residents."

Sherpa recently launched <a href="https://www.apartments.com.au/new-apartments/flourish-soleira-palm-beach-1150-1160-gold-coast-highway-palm-beach-qld-4221">Flourish Soleira</a>, its third instalment of the Flourish brand in Palm Beach following Flourish Oasis and <a href="https://www.apartments.com.au/new-apartments/amargo-6-12-sixth-avenue-palm-beach-qld-4221">Flourish Amargo</a>.

Sherpa sells out Flourish Oasis in booming Palm Beach

Urban Property Group's <a href="https://www.apartments.com.au/new-apartments/la-vera-macquarie-park-94-talavera-road-macquarie-park-nsw-2113">La Vera</a> is leading the next phase of Macquarie Park's residential evolution, with the new apartment development set to become the first of several new apartment projects in the precinct to complete.

The 169-apartment building has now topped out ahead of its scheduled completion in the third quarter of 2026, as new residential investment continues to reshape one of Sydney's largest employment hubs into a true mixed-use precinct.

[smartcode_project:default project_id=134951 project_image_fid=368645]

Cox Architecture has designed La Vera to capture the best of its unique positioning on Talavera Road, orienting the building towards Lane Cove National Park.&nbsp;The building features a sculpted northern façade with flowing curves inspired by the surrounding landscape, while its city-facing elevation adopts a more structured architectural expression to maximise skyline views.

"The vision for the project was to conceive a building that adopted an organic and curvilinear form to the northern portion that faces the Lane Cove National Park," <a href="https://www.apartments.com.au/architects/cox-architecture">Cox Architecture</a> Director Felipe Miranda said.

"The residents that reside in the northern portion of the building benefit by having beautifully crafted curved balconies that speak to the natural context and heighten the relationship of their internal living spaces to the external balconies."

[smartcode_project:default project_id=134951 project_image_fid=358802]

La Vera offers a diverse mix of one, two, three, and four-bedroom configurations, with prices currently starting from $740,000. Buyers so far have been a mix of Sydney-based investors,&nbsp;metro commuters, owner-occupiers and downsizers from surrounding North Shore suburbs.

Both investors and owner-occupiers have been drawn to La Vera's proximity to Macquarie University, Macquarie University Hospital, Macquarie Centre and the Sydney Metro, infrastructure that supports both strong rental demand and a convenient lifestyle for residents.

The apartments feature full-height glazing, timber flooring throughout living areas, stone kitchen benchtops, SMEG appliances, floor-to-ceiling bathroom tiling and ducted air conditioning.

Residents will have access to a rooftop recreation level featuring a swimming pool, sauna, barbecue facilities and landscaped relaxation areas, complemented by additional communal space at ground level. Many apartments enjoy uninterrupted views across Lane Cove National Park, reinforcing the project's connection to its natural setting.

[smartcode_project:default project_id=134951 project_image_fid=364551]

<a href="https://www.apartments.com.au/developers/urban-property-group">Urban Property Group</a>, a family-owned developer and builder with nearly four decades of experience, holds a 4.5-star iCIRT rating and was Australia's first developer to introduce 10-Year Latent Defects Insurance (LDI). La Vera is the first apartment development in <a href="https://www.apartments.com.au/developments/macquarie-park-nsw-2113">Macquarie Park</a> approved to offer the additional insurance protection, alongside a five-year warranty on SMEG appliances.

Urban Property Group CEO Patrick Elias said the additional protection reflects changing buyer expectations in the off the plan market.

"Consumers are a lot more weary and a lot more concerned in buying off the plan than they ever have been. Having LDI is a tool to portray the confidence that we have in our product, and a confidence we want buyers to share," Elias said.

Following completion of the building later this year, buyers will move into their apartments well before Christmas.

GUEST OBSERVER
Domestic animals are rarely associated with Antarctica. However, before non-native species (bar humans) were excluded from the continent in the 1990s, many travelled to the far south.
These animals included not only the obvious sledge dogs, but also ponies, sheep, pigs, hamsters, hedgehogs and a goat. Perhaps the most curious case occurred in 1933, when US Admiral Richard E. Byrd’s second Antarctic expedition took with it three Guernsey cows. 
The cows, named Klondike Gay Nira, Deerfoot Guernsey Maid and Foremost Southern Girl, plus a bull calf born en route, spent over a year in a working dairy on the Ross Ice Shelf. They returned home to the US in 1935 to considerable celebrity. 
Keeping the animals healthy in Antarctica took a lot of doing – not least, hauling the materials for a barn, a huge amount of feed and a milking machine across the ocean and then the ice. What could have possessed Byrd to take cows to the icy south? 
The answer we suggest in our recently published paper is multi-layered and ultimately points to Antarctica’s complex geopolitical history.
Solving the “milk problem”
The cows’ ostensible purpose was to solve the expedition’s so-called “milk problem”. By the 1930s, fresh milk had become such an icon of health and vigour that it was easy to claim it was needed for the expeditioners’ well-being. Just as important, however, were the symbolic associations of fresh milk with purity, wholesomeness and US national identity. 
Powdered or malted milk could have achieved the same nutritional results. Previous expeditions, including those of Ernest Shackleton and Roald Amundsen, had survived just fine with such products. What’s more, William Horlick of Horlick’s Malted Milk sponsored Byrd’s second Antarctic expedition; the seaplane Byrd used was named for this benefactor. 
So if fresh milk was not actually a health requirement, and other forms were readily available, why go to the trouble of lugging three cows and their accoutrements across the ice?
Maximising publicity
The cows represented a first, and Byrd well knew that “firsts” in the polar regions translated into media coverage. The expedition was privately funded, and Byrd was adept at attracting media attention and hence sponsorship. His backers expected a return, whether in the form of photographs of their product on the ice or mentions in the regular radio updates by the expedition. 
The novelty value that the cows brought to the expedition was a valuable asset in its own right, but Byrd hedged his bets by including a pregnant cow – Klondike was due to give birth just as the expedition ship sailed across the Antarctic Circle. The calf, named “Iceberg”, was a media darling and became better known than the expeditioners themselves. 
The celebrity attached to the cows helped the expedition remain in the headlines throughout its time in Antarctica, and they received an enthusiastic welcome upon its return. Although the unfortunate Klondike, suffering from frostbite, had to be put down mid-expedition, her companions made it home in good condition. They were feted on their return, meeting politicians in Washington, enjoying “hay cocktails” at fancy hotels, and making the front page of The New York Times.
It would be easy, then, to conclude that the real reason Byrd took cows south was for the publicity he knew they would generate, but his interest in the animals may also have had a more politically motivated layer.
Eyeing a territorial claim
A third reason for taking cows to Antarctica relates to the geopolitics of the period and the resonances the cows had with colonial settlement. By the 1930s several nations had claimed sectors of Antarctica. Byrd wanted the US to make its own claim, but this was not as straightforward as just planting a flag on the ice. 
According to the Hughes Doctrine, a claim had to be based on settlement, not just discovery. But how do you show settlement of a continent covered in ice? In this context, symbolic gestures such as running a post office – or farming livestock – are useful. 
Domestic animals have long been used as colonial agents, and cattle in particular were a key component of settler colonialism in frontier America. The image of the explorer-hero Byrd, descended from one of the First Families of Virginia, bringing cows to a new land and successfully farming them evoked this history. 
The cows’ presence in Antarctica helped symbolically to turn the expedition base – not coincidentally named “Little America” – into a frontier town. While the US did not end up making a claim to any sector of Antarctica, the polar dairy represented a novel way of demonstrating national interest in the frozen continent.
The Antarctic cows are not just a quirky story from the depths of history. As well as producing milk, they had promotional and geopolitical functions. On an ice continent, settlement is performed rather than enacted, and even Guernsey cows can be more than they first seem.

Cows in Antarctica? How one expedition milked them for all their worth

GUEST OBSERVER
Icebergs breaking off Antarctica, even massive ones, do not typically concern glaciologists. But the impending birth of a new massive icebergcould be more than business as usual for the frozen continent. 
The Larsen C ice shelf, the fourth-largest in Antarctica, has attracted worldwide attention in the lead-up to calving an iceberg one-tenth of its area – or about half the area of greater Melbourne. It is still difficult to predict exactly when it will break free.
But it’s not the size of the iceberg that should be getting attention. Icebergs calve all the time, including the occasional very large one, with nothing to worry about. Icebergs have only a tiny direct effect on sea level. 
The calving itself will simply be the birth of another big iceberg. But there is valid concern among scientists that the entire Larsen C ice shelf could become unstable, and eventually break up entirely, with knock-on effects that could take decades to play out.
Ice shelves essentially act as corks in a bottle. Glaciers flow from land towards the sea, and their ice is eventually absorbed into the ice shelf. Removal of the ice shelf causes glaciers to flow faster, increasing the rate at which ice moves from the land into the sea. This has a much larger effect on sea level than iceberg calving does.
While the prediction that Larsen C could become unstable is based partly on physics, it is also based on observations. Using aerial and satellite images, scientists have been able to track very similar ice shelves in the past, some of which have been seen to retreat and collapse. 
<h2>The death of an ice shelf</h2>
The most dramatic ice shelf collapse observed so far is that of Larsen C’s neighbour to the north – the imaginatively named Larsen B. Over the course of just six weeks in 2002 the entire ice shelf splintered into dozens of icebergs. Almost immediately afterwards, the glaciers feeding into it sped up by two to six times. Those glaciers continue to flow faster to this day. 
In our new study, published in Earth and Planetary Science Letters, we turn the clock back even further to look at the Wordie ice shelf, on the west coast of the southern Antarctic Peninsula, which began to retreat in the 1960s and eventually disappeared in January 2017. 
Over the past 20 years, observations have shown that the main glacier feeding into the Wordie ice shelf, the Fleming Glacier, has sped up and thinned. Compared with the glaciers feeding Larsen B and C, Fleming Glacier is massive: 80km long, 12km wide, and 600m thick at its front.

We used historic aerial photographs from 1966 to create an elevation map of the Fleming Glacier, and compared it to elevation measurements from 2002 to 2015. Between 1966 and 2015 the Fleming Glacier thinned by at least 100m near the front. The thinning rate, which is the elevation change rate, rapidly increased: the thinning rate after 2008 is more than twice that during 2002 to 2008, and four times the average rates from 1966 to 2008.

Ice thinning rate of the Fleming Glacier region during (a) 2002-2008 and (b) 2008-2015. Author provided
Ice flow speeds have also increased by more than 400m per year at the front since 2008. This is <a href="https://www.the-cryosphere-discuss.net/tc-2017-75/">the largest speed change in recent years of any glacier in Antarctica</a>. These changes all point to ice shelf collapse as the cause.
We estimate the total glacier ice volume lost from all glaciers that feed the Wordie is 179 cubic kilometres since 1966, or 319 times the volume of Sydney Harbour. The weight of this ice moving off the land and into the ocean has caused the bedrock beneath the glaciers to lift by more than 50mm. 
Other research has suggested this lift could have acted to slow the glacier’s retreat, but it’s clear that the bedrock deformation has not stopped the ice movement speeding up. It seems the Fleming Glacier has a long way to go before it will return to a new stable state (in which snowfall feeding the glacier equals the ice flowing into the oceans).
Fifty years after the Wordie Ice Shelf began to collapse, the major feeding glaciers continue to thin and flow faster than before. 
We can’t yet predict the full consequences of the new iceberg calving from Larsen C. But if the ice shelf does begin to retreat or collapse, history tells us it is very possible that its glaciers will flow faster – making yet more sea level rise inevitable.

When you think of Antarctica, you probably picture vast, continuous ice sheets and glaciers, with maybe a penguin or two thrown in.
Yet most Antarctic plants and animals live in the permanently ice-free areas that cover about 1 percent of the continent. Our new research predicts that these areas could grow by a quarter during this century, with mixed prospects for the species that currently live there. 
Besides everyone’s favourite Emperor and Adélie penguins, terrestrial Antarctic species also include beautiful mosses, lichens, two types of flowering plants, and a suite of hardy invertebrates such as nematodes, springtails, rotifers and tardigrades, many of which are found nowhere else on Earth. Tardigrades – tiny creatures sometimes nicknamed “waterbears” – are so tough they can survive in space.
Antarctica’s ice-free areas are currently limited to a scattering of rocky outcrops along the coastline, or cliff faces, or the tops of mountain ranges. They form small patches of suitable habitat in a huge sea of ice, much like islands. 
As a result, the plants and animals that live there are often isolated from each other. But as Antarctica’s climate warms, we expect ice-free areas to get bigger and eventually start joining up. This would create more habitat for native species, but also new opportunities for non-native species to spread. 
Our study, published today in Nature, forecasts that climate change will expand Antarctica’s ice-free areas over the course of this century. Under the most severe scenario that we modelled (which is also the one on which the globe is currently tracking), more than 17,000 square km of new ice-free area could emerge across the continent by 2100. 
This would increase the current total ice-free area by nearly a quarter. The majority of this new ice-free land will be on the Antarctic Peninsula, which could have three times as much ice-free area as it does today.  
Brave new world
As the ice-free areas expand, the distances between them will decrease, giving plants and animals more opportunity to spread through the landscape. On the Antarctic Peninsula, which has already warmed more than anywhere else in Antarctica, many of the ice-free patches will expand so much that they will start joining together.
Will this increase in habitat availability benefit the plants and animals that live there? It will definitely provide new opportunities for some native plants and animals to expand their range and colonise new areas. The warming climate may also give a boost to species that are currently hampered by the lack of warmth, nutrients and water. Some Antarctic mosses, for example, are expected to grow faster as temperatures rise, and Antarctica’s two flowering plant species are already expanding southward.
However, the potential benefits seem likely to be outweighed by the negatives. The joining-up of habitat patches could allow species that have been isolated for much of their evolutionary past to meet suddenly. If the newcomers to a particular area outcompete the native species, then it may lead to localised extinctions. Over the coming centuries this could lead to the loss of many plants and animals, and the homogenisation of Antarctica’s ecosystems.
Antarctic aliens
An even bigger concern is that Antarctica’s great thaw could provide new opportunities for species to invade. Antarctica’s best bulwark against non-native species is its harsh climate and extreme weather, to which native Antarctic species have spent many thousands of years adapting. 
We already know that many plants and invertebrates are reaching Antarctica, most often in food or cargo shipments. As the climate warms, some of these non-native species may be able to establish themselves on the Antarctic Peninsula, and the increasing connectivity will allow them to easily move through the landscape. Many of these animals and plants may become invasive, competing with the native species for space and resources. 
We don’t know how Antarctica’s species will cope with the increasing competition. But if the sub-Antarctic islands provide any indication, the outlook is depressing. Australia’s World Heritage-listed Macquarie Island, for example, was severely impacted by invasive cats, rats, rabbits and mice (although it has since been declared free of these pests after an intensive eradication effort).
Several non-native species have already come to Antarctica, including the invasive annual meadowgrass Poa annua (a common weed around the world), which has colonised newly ice-free areas left behind by retreating glaciers. It is thought to outcompete Antarctica’s native plants, although we don’t yet know what the impact will be on animals. 
Humans – both scientists and tourists – are key transporters of non-native species to the continent, and tourist numbers continue to grow (almost 37,000 visited in the 2016-17 summer). 
Biosecurity is paramount for the ongoing protection of Antarctica. If bags, shoes, clothes and field equipment are not properly cleaned and inspected before arriving on the continent, then non-native seeds, microbes and insects could be transported to Antarctica and begin to spread. 
We call for protection of ice-free areas that will remain intact in a changing climate, and for the Antarctic scientific and tourism communities to pinpoint key areas where greater biosecurity and monitoring for invasive species may be needed.
