“We have a 10-year pipeline of infrastructure projects in the lead up to and beyond Brisbane 2032. And we are creating good, secure jobs in the key industries that will help us decarbonise.”

However, Miles warned that such significant population growth – fuelled by interstate and overseas migration – would require changes to planning laws and building types.

For example, south-east Queensland’s population will continue to age and more people will live by themselves, a demographic issue identified by Brisbane City Council earlier this year.

The proportion of one-person households will increase substantially from 23.4 per cent in 2021 to 40.5 per cent in 2046.

Miles said the demographic shift would lead to more units, townhouses and modern terrace houses, and ongoing efforts to house people closer to employment, service and retail centres.

“So even without counting the massive population increase, we still need more homes to house the same number of people,” Miles said.

“These changes mean we need more, smaller homes in the mix, to deliver more housing options.”

More details on the likely distribution of population growth, and areas expected to accommodate more people, will be in the new draft regional plan.
