Projections of 35 million people by 2050
The 35-million projection was prepared by the Commonwealth Treasury. It parallels recent Australian Bureau of Statistics and state government population projections. All assume that the current record high net migration levels and high fertility (relative to a few years ago) will continue.
If Australia reaches 35 million by 2050, choices about desired family size will play a minor role. The projections all assume that fertility will remain below the long-term replacement level. As a result, some 85 per cent of the projected growth from 22 million today to 35 million will derive from net overseas migration (including children born to migrants once in Australia).

By now, 64 per cent of Australia's 22 million people live in capital cities. But our hottest population spots are the satellites within 150km of their state capital, such as Mandurah outside Perth, the Gold Coast-Tweed and Sunshine Coast areas outside Brisbane and Ballarat outside Melbourne. These satellites act as economic and service hubs for their regions. They also are close enough to their capital city to tap its agglomeration of customers, suppliers and jobs. And they can relieve congestion and cost pressures in the capitals.
Firms might be prepared to drive an hour or so to do business in the big smoke, suggests Daley. But the costs rise and the interest drops off when it takes more than two hours.

VAST satellite cities could be built between Brisbane and the Gold Coast to ease the crippling population pressures threatening southeast Queensland, according to Logan Mayor Pam Parker.
Speaking on the Gold Coast at
The Courier-Mail's Our Future Your Say forum, Cr Parker said the areas around Logan and Ipswich, which still held large tracts of greenfill land otherwise rare in the southeast corner, would be perfect for taking the strain off the major cities to the north and south which are already battling housing affordability and land availability problems.
"These areas (Logan and Ipswich) have vast greenfill space which could house satellite cities where people could live, work and play," she said.
"This would help to ease the gridlocked traffic on our freeways and pressures on our existing infrastructure."
