This week, Cotality released its housing affordability report for the September quarter of 2025, which reported abysmal affordability across the nation for both purchases and rent.

In response, AMP chief economist Shane Oliver produced a report explaining how Australia’s mass immigration policy has eroded housing affordability by creating a structural imbalance between supply and demand.
Oliver explains how the nation’s housing market became structurally undersupplied when the federal government ramped up immigration in the mid-2000s, expanding Australia’s population growth by 150,000 annually.
