Are Australian Cities Truly Climate-Proof? Exploring Urban Resilience

Australia’s cities are no strangers to extreme weather events, from raging bushfires to devastating floods. As the world warms and climate change continues to impact weather patterns, many Australians are asking the same question: can any city truly be climate-proof?

With rising temperatures and increasingly unpredictable weather, the concept of “climate havens” – locations considered safe from the worst effects of climate change – has emerged.

But is it realistic to think any place is immune?

Extreme Weather Events in Australia

The idea that some areas might be shielded from environmental disasters has gained attention, especially as people seek safer places to live.

Take towns like Hobart in Tasmania or Toowoomba in Queensland – often mentioned as potential “climate havens” due to their milder climates, lack of coastal exposure, or higher elevations.

But even these places are not completely protected.

Australia has experienced unprecedented bushfires, such as the 2019-2020 Black Summer fires, which engulfed regions previously thought less vulnerable. Torrential flooding in places like Lismore and Brisbane has also demonstrated that even inland towns are not immune to the impacts of extreme weather.

A False Sense of Security?

The idea of climate havens has been popularised in some regions by the property market, often promoted to attract those looking to escape from more vulnerable locations, such as the fire-prone Blue Mountains or flood-risk coastal areas.

Mountainous and inland regions, while generally safer from sea-level rise, are not without their own risks. Heavy rains, fuelled by warmer ocean temperatures, can lead to catastrophic flash flooding in these areas.

During the 2022 east coast floods, entire communities were left underwater as rivers and creeks burst their banks in response to intense rain, with tragic loss of life and significant damage to homes and infrastructure.

The Role of Climate Change in Intensifying Weather Events

As the planet warms, scientists predict that extreme weather events will become both more frequent and more severe.

In Australia, this means more intense bushfire seasons, longer droughts, and more powerful storms. Recent studies suggest that climate change is also making tropical cyclones stronger and allowing them to retain more energy as they move inland – heightening the risk to inland cities.

In places previously thought safe from flooding, like Western Sydney, urban sprawl and increased rainfall due to climate change are creating new hazards.

Australia’s flood risk maps – similar to international counterparts – may be underestimating the true scale of flood danger. Many homes at risk of flooding do not have the necessary insurance, leaving residents vulnerable to financial ruin after disasters.

Safer, but Not Safe

While no corner of Australia will be untouched by climate change, certain places may be a bit safer given their unique geographical traits and reduced exposure to particular hazards like encroaching sea levels or sweltering heat.

These regions typically boast gentler climates, sit at higher elevations, or find themselves less susceptible to fire or flood dangers.

1. Hobart, Tasmania
   Why it’s considered safer: Hobart is frequently hailed as one of Australia’s most climate-resilient cities, thanks to its cooler, more temperate climate and relatively low risk of extreme heatwaves, bushfires, or flooding. Tasmania’s southern location makes it less likely to endure the harshest climate change effects, such as extended heatwaves or tropical storms that typically affect northern Australia.
   Potential risks: Hobart isn’t entirely free of risk – bushfires can occur and its coastal position means some areas might face threats from rising sea levels. Though when compared to mainland Australia, it remains a more promising choice for a long-term climate resilient location.

2. Toowoomba, Queensland
   Why it’s considered safer: Perched on the Great Dividing Range at a higher altitude, Toowoomba is somewhat insulated from the immediate impacts of coastal storms and sea-level rise. It’s renowned for its cooler temperatures compared to Queensland’s coastal cities and is less prone to severe heatwaves and tropical cyclones.
   Potential risks: Toowoomba does face some risk of flash flooding, as evidenced by the devastating floods of 2011, but with enhanced urban planning and water management, it could sustain a strong level of resilience.

3. Ballarat, Victoria
   Why it’s considered safer: Nestled inland and at a higher elevation, Ballarat enjoys a relatively cool climate. Its location shields it from rising sea levels and it is distanced from the most extreme fire-prone regions. Ballarat’s temperate conditions also make it less vulnerable to extreme heat events.
   Potential risks: Like many areas, Ballarat may experience extreme weather changes due to climate shifts, but its overall geographic position provides a buffer against more severe impacts that coastal or lower-lying areas might recieve.

4. Orange, New South Wales
   Why it’s considered safer: Situated in the Central Tablelands, Orange benefits from a cool temperate climate and high elevation, which reduces its risk of extreme heat. Its inland location also protects it from the impacts of rising sea levels or coastal erosion.
   Potential risks: While Orange is more resilient to flooding and bushfires than many other parts of New South Wales, no region is completely immune from climate change, and droughts could pose challenges.

5. Canberra, Australian Capital Territory
   Why it’s considered safer: Canberra, Australia’s capital, is situated inland, far from coastal threats like rising sea levels and tropical storms. Its planned infrastructure and cooler climate make it less vulnerable to extreme weather events. Canberra also places a strong emphasis on sustainable urban planning and green initiatives, enhancing its resilience.
   Potential risks: Like many parts of Australia, Canberra remains vulnerable to bushfires, particularly with the surrounding bushland. The 2003 Canberra bushfires highlighted this, though the city has since bolstered its fire mitigation strategies.

6. Launceston, Tasmania
   Why it’s considered safer: Much like Hobart, Launceston has a cooler and more temperate climate. It is located inland and enjoys some protection from coastal threats such as sea-level rise. The town is surrounded by fertile farmland, reducing risks of intense bushfires.
   Potential risks: Launceston has some flood risk due to its river valley location, but flood mitigation efforts are in place. The cooler climate also diminishes vulnerability to extreme heat.

7. Bendigo, Victoria
   Why it’s considered safer: Inland and elevated, Bendigo offers a degree of protection from coastal flooding and sea-level rise. Its temperate climate and relative distance from bushfire-prone forests make it less susceptible to the worst impacts of climate change.
   Potential risks: Bushfires can still pose a serious threat, particularly during drought periods, but overall, Bendigo’s inland location provides resilience against many extreme weather events.

The Search for Climate Havens in Australia

A recent survey by Property Council of Australia found that climate resilience is now a key factor for many homebuyers. Though day-to-day concerns like job opportunities, lifestyle, and housing affordability still dominate the decision-making process for most.

The fastest-growing regions in Australia are also among the most vulnerable to climate change impacts.

Coastal regions like the Sunshine Coast and Gold Coast continue to attract new residents, despite their heightened risks from coastal erosion and rising sea levels. This trend may shift as insurers withdraw coverage from high-risk areas, forcing people to reconsider where they live.

Australia’s Climatic Predicaments in a Global Context

When you stack Australia’s climate situation against that of other nations, multiple challenges are revealed.

Geographic Vulnerability

As the world’s driest inhabited continent, Australia grapples with distinctive hurdles. Unlike the sprawling landscapes of the United States or China, Australia is short on internal “climate havens.”

Coastal Concentration

With about 85% of Aussies residing within a mere 50km of the coastline, the nation is more susceptible to rising sea levels than inland-focused countries like Germany or Switzerland.

Bushfire Risk

Although the United States and Canada also battle wildfires, Australia’s unique vegetation, especially the eucalyptus trees, coupled with its climate, makes bushfire threats particularly severe.

Water Scarcity

In contrast to water-abundant countries such as Canada or Norway, Australia’s water woes are acute.

Cities like Cape Town in South Africa have faced “Day Zero” drought scenarios, offering valuable lessons for Australian urban water planning.

Heat Extremes

Australian cities endure some of the globe’s fiercest urban heat extremes.

While Middle Eastern cities might see higher peak temperatures, the length of Australia’s heatwaves poses a distinct challenge.

Adaptive Capacity

Thanks to our developed economy and solid institutions, akin to other developed nations, means we have the resources to adapt. Yet, the sheer scale and frequency of climate events here push this capacity to its limits more than in many other developed regions.

The Importance of Resilient Infrastructure

The real solution to creating climate-resilient cities lies not in geography alone, but in infrastructure and planning.

Research shows that regions with well-maintained infrastructure – like updated flood levees, bushfire mitigation systems, and planned drainage networks – tend to fare better during extreme weather events.

Projects like wetlands restoration and improving dam capacities are being explored as ways to mitigate the risk of flooding. Similarly, fire-prone areas are increasingly planting fire-resilient vegetation and clearing land around homes to create natural barriers.

These measures don’t eliminate the risks, but they can significantly reduce the damage caused by climate events.

Can We Truly Climate-Proof a City?

It’s unlikely that any city can be entirely future-climate-proof, but some will be better equipped than others to handle the challenges ahead.

Urban planning that integrates climate resilience – like flood-resistant infrastructure, sustainable building practices and efficient water management systems – will become essential for cities aiming to protect their residents from the growing and evolving threats of climate change.

Australia’s future cities will need to adopt a proactive approach to climate adaptation, learning from past disasters and preparing for a more uncertain future.

In a world where no location is completely safe, the best way forward is to focus on resilience, adaptation and sustainable growth.
