Australia just hit 28 million people. By 2065, we will have 40 to 41 million. Sydney will be the size of New York. Melbourne will be bigger than London. So what does that mean for our roads, our rail, our housing supply, and the property market? Mark Bouris sits down with Adam Copp, Chief Executive Officer of Infrastructure Australia, the federal government’s independent advisor on infrastructure investment, planning and reform, to unpack what this population surge really means for everyday Australians. They cover:
- Why Sydney and Melbourne are heading toward megacity scale and what that demands of our infrastructure
- The mass transit projects already underway and the ones we still need to build
- Why housing supply and infrastructure investment must move together, and why they so often do not
- The 30-minute rule of thumb that determines quality of life for commuters
- How Western Sydney’s Aerotropolis is being built as a city from the ground up
- The role of superannuation funds in financing the next generation of infrastructure
- What climate change and geopolitical instability mean for Australia’s long-term resilience
- Why Adam Copp is optimistic about Australia’s future, if we are willing to build for it
Whether you are a property buyer, investor, or simply trying to understand where Australia is heading, this is a conversation that cuts through the noise and gets to what actually matters.
