The mathematics are sobering. At the current annual absorption rate of less than 50,000 sqm nationally, and with total vacancy sitting around 4.36 million sqm, meaningful vacancy compression will require either a substantial acceleration in tenant demand or significant stock withdrawals. Markets like Melbourne CBD at 19.0 per cent vacancy face particularly extended timelines for recovery, while even outperformers like Brisbane and Sydney remain well above historical norms. Adelaide's improvement to 15.5 per cent demonstrates what balanced supply and demand can achieve, but even this represents vacancy substantially elevated compared to the sub-10 per cent rates that characterised healthy markets pre-pandemic.
The positive development is that new supply will eventually taper as construction costs have reached levels where CBD development is economically unviable at current rents. The projects currently completing represent the tail end of the development cycle rather than the beginning of a new wave. However, even with minimal new supply ahead, the existing vacancy overhang means that meaningful improvement will be measured in years rather than quarters. The flight to quality dynamic adds another layer of complexity, with premium assets likely to see earlier vacancy compression while secondary buildings face extended periods of oversupply and potentially permanent conversion to alternative uses.
The return of positive absorption represents genuine progress after years of contraction, with businesses demonstrating renewed confidence in office-based work and corporate expansion. Queensland's strength, Sydney's recovery, and Melbourne's stabilisation all point to improving fundamentals. However, expectations need to remain grounded in the reality that vacancy rates substantially above historical norms will persist for the foreseeable future, creating ongoing pressure on rental growth and capital values, particularly for assets outside the premium grade. The market has turned a corner from decline to recovery, but the recovery itself will be a gradual, multi-year process rather than a swift return to pre-pandemic conditions.
