Melbourne’s Megacity Future: A Regional Solution?

Melbourne is on track to house over 10 million people by 2101, with Victoria’s population growing by one person every four minutes and 40 seconds. This rapid growth has sparked concerns about the city’s megacity future, particularly in terms of preserving its character and infrastructure.

The issue at hand extends beyond accommodating more people; it also involves managing the strain on resources. Housing over 5 million extra residents would require an additional 2 million dwellings, putting immense pressure on Melbourne’s infrastructure. The dilemma is clear: do we allow the city to sprawl further or redirect growth towards established transport hubs and regional towns?

Decentralisation offers a potential solution to Melbourne’s growth woes. This concept involves proactively investing in regional centres and infrastructure to create more sustainable cities that balance population growth with environmental concerns. Decentralisation has its roots in Australia’s post-WWII era, when politicians like Gough Whitlam proposed decentralising growth by investing in regional centres and infrastructure.

However, this approach requires significant federal commitment and investment, including fast rail links between eastern coast capitals and regional centres. Dr Elizabeth Taylor, a senior lecturer at Monash University, argues that decentralisation could be a more effective model than megacity growth. “To build and nurture real liveable cities, you have to stick at it for 20 or 30 years and well beyond any electoral cycle,” she warns.

The experience of New South Wales in the early 2000s serves as a cautionary tale. When then-premier Bob Carr declared Sydney full and stalled infrastructure investment, the city suffered from decades of underinvestment. This lesson highlights the importance of planning for growth, rather than simply reacting to it.

Australia’s colonial history has left an enduring legacy in its city planning. Our coastal capitals were established as port-dominated settlements, influenced by European fears about the desert interior. This top-down approach to urban development has led to sprawling suburbs and inadequate infrastructure. As Pat Fensham of the Planning Institute of Australia notes, allowing Melburnians to dictate the overall size of their city would give existing residents too much authority and future residents none.

However, decentralisation offers a potential solution to Melbourne’s growth woes by proactively investing in regional centres and infrastructure. By creating more sustainable cities that balance population growth with environmental concerns, we can create a better model – one that prioritises people over sprawl. As Dr Taylor notes, “The argument goes around and around in circles, government won’t invest because there’s no accompanying urban plan, but there is no urban plan because there’s no infrastructure.”

Planning for growth requires a long-term vision, significant investment, and a willingness to challenge the status quo. It’s not just about accommodating more people; it’s also about creating sustainable cities that benefit all residents. Melbourne’s megacity future is far from a foregone conclusion. By exploring regional solutions like decentralisation and prioritising people over sprawl, we can create more sustainable and liveable cities for generations to come.

In the end, it’s not just about numbers; it’s about creating a city that works for everyone.
