Australia's office market is sending conflicting signals, and property investors need to read between the headlines. Yes, demand is rebounding strongly. Yes, tenant take-up is at its best level since 2018. But here's what the market isn't telling you: landlords of secondary-grade buildings are in deepening trouble.
National office vacancy sits at 15.9 per cent, up from 15.1 per cent six months earlier. Yet at the same time, Australia's CBD office markets just recorded their strongest occupier demand since the pre-pandemic peak, with net absorption reaching 364,635 square metres in the 12 months to January 2026. The numbers speak for themselves: something doesn't add up.
The answer lies in a phenomenon real estate agents call the 'flight to quality'. Premium office buildings in Brisbane, Sydney, and Melbourne are experiencing genuine tightness. Brisbane's premium CBD vacancy fell sharply to just 3.8 per cent from 7.3 per cent a year earlier. Sydney's Core CBD is holding up reasonably well. Yet overall CBD vacancy rates across Sydney and Melbourne remain stubbornly elevated because secondary and older buildings are being abandoned by tenants seeking modern, sustainably certified A-grade stock.
The numbers reveal the problem. Over the 12 months to January 2026, national office net absorption reached 364,635 square metres. Sounds healthy. But 389,514 square metres of new office space was delivered over the same period, nearly double the space absorbed. That gap is the crisis.
What the market hasn't priced in yet is that this supply-demand mismatch will take years to resolve. At the current absorption rate of approximately 365,000 square metres annually, and with total national vacancy sitting around 4.36 million square metres, meaningful vacancy compression is still years away. For landlords, this translates to years of elevated costs, especially in a rising interest rate environment where borrowing is expensive.
Strip away the buzz and the fundamentals show a landlord class split into two groups. Owners of premium, modern, sustainably certified buildings are winning. They're raising rents and commanding strong occupancy. Everyone else is offering landlord-funded fit-out incentives to simply keep tenants from leaving.
For property investors, the signal is clear: location, specification, and amenity now determine outcomes far more than the headlines suggest. The disruption is already underway.
