Australian rental affordability has regressed to levels not seen since 2008, signaling a profound structural imbalance in the national housing market. While headline news often focuses on the difficulty for tenants, from a structural perspective, this data confirms the extreme scarcity of available housing stock relative to a growing population.
The realestate.com.au Rental Affordability Index reveals that a typical household earning $124,000 can now afford only 37% of rental listings nationwide. In high-growth markets like Western Australia and South Australia, that figure plummets to 24% and 19% respectively. What the data actually signals is that the “rental ceiling” is being tested by income constraints, yet the underlying lack of supply continues to drive prices higher.
This is often misunderstood as a temporary “spike.” In reality, the fact that rents in Perth have nearly doubled since the pandemic highlights a permanent repricing of shelter. When typical earners can only access less than a quarter of the market in major states, it forces a shift in household behaviour—increased share-housing and a slowdown in household formation—which further masks the true depth of the housing deficit.
At Infinite Wealth, we look beyond the surface-level hardship to the structural reality: property remains an essential utility. When affordability hits these historic lows, it creates a “rental floor” that underpins property values. For investors, this environment demands a focus on high-demand corridors where employment remains strong, as these areas are most resilient to affordability-driven migration.
