While the national vacancy rate saw a marginal increase to 1.4% in December 2025, a structural analysis reveals that the Australian rental market remains in a state of chronic undersupply. This slight “easing” from 1.3% is widely considered a seasonal anomaly—typical of the end-of-year period—rather than a shift in fundamental market dynamics.
What actually matters here is the comparison to long-term averages. A “balanced” market is generally defined by a vacancy rate of 3%. With the national average sitting at less than half that figure, the market continues to heavily favour landlords. In jurisdictions like Perth (0.7%), Adelaide (0.9%), and Hobart (0.4%), the vacancy rate is so low that it effectively represents a total absence of available stock, driving intense competition among tenants and sustained upward pressure on rents.
From a structural perspective, the disparity between cities like Melbourne (2.0%) and Hobart (0.4%) highlights the importance of location-level nuance. While Melbourne has seen a slight increase in availability, it remains below the threshold for a balanced market. Meanwhile, the “tightest” markets are those where the delivery of new supply has been most constrained by geography and construction lags.
This is why surface-level analysis falls short—an increase of 0.1% in the vacancy rate is not a sign of a market “crash” or even a “cooling”; it is a minor fluctuation within a broader crisis of supply. At Infinite Wealth, we view these vacancy figures as a primary indicator of income security. For long-term investors, low vacancy rates ensure consistent cash flow and provide the fundamental support necessary for future capital growth.
