Canberra's Office Market Is Shifting Under Your Feet — Here's What Residents Need to Understand

Canberra's office vacancy rate hit 11.4 per cent in the first quarter of 2026, according to Property Council of Australia figures — the highest it has been since the mid-1990s restructuring of the Australian Public Service. That number isn't just an abstraction for landlords and fund managers. It has direct consequences for anyone who uses the city centre, pays local rates, or hopes to see their suburb grow.

The timing matters. Nationally, AI data centre operators are competing aggressively for industrial land on the urban fringe, a dynamic that is already squeezing freight and logistics businesses in outer Canberra. Meanwhile, investors have been retreating from property markets in Melbourne and other capitals following recent budget measures, and some of that caution is spilling into the ACT. The federal government — the territory's dominant employer and by far its largest office tenant — is itself in the middle of a long-term rationalisation of its workspace footprint, consolidating agencies and embracing flexible work policies that reduce the square metreage each public servant actually occupies.

What's Happening in the City and Why It Affects You

Walk along Northbourne Avenue or through the Civic core on a Tuesday afternoon and the half-empty lobbies tell the story more plainly than any data set. Buildings that were fully leased to Commonwealth departments five years ago now carry 'available' signs. Nishi, the award-winning mixed-use development in NewActon, and Canberra Square on City Walk both still attract strong foot traffic, but they are outliers in a precinct where ground-floor retail is struggling to find tenants willing to commit to long leases.

The practical consequence for residents: the mix of businesses at street level is changing. Cafes and convenience retail that depend on weekday office workers have closed or reduced hours across the inner north, particularly around Mort Street in Braddon and along Marcus Clarke Street in the city. Some landlords have responded by converting ground-floor commercial tenancies to short-term hospitality pop-ups or community uses — a sticking plaster, not a structural fix.

The Canberra CBD office market recorded average prime net face rents of around $420 per square metre annually as of late 2025, down roughly 8 per cent in real terms from their 2022 peak. Incentive packages — rent-free periods and fit-out contributions — have ballooned. A tenant signing a 10-year lease on a B-grade Civic building can now negotiate incentives worth 35 to 40 per cent of gross rent, according to commercial leasing advisers active in the market. That is good for businesses hunting for space, but it signals landlords are under pressure, and pressure on landlords eventually translates to pressure on the rates base and the territory's budget.

What This Means for Everyday Decisions

For residents, the shift creates real opportunities and real risks. On the opportunity side, businesses looking to relocate or start up can access central Canberra space at the most competitive rents in a generation. The ACT Government's Office of the Industry Development Branch has flagged incentive programs to attract health and technology firms into vacant civic space — worth watching if you work in those sectors or have a stake in diversifying the local economy beyond the public service.

The risk is longer-term. A hollowed-out city centre depresses the amenity that makes Canberra attractive to skilled workers and their families. Empty offices also slow the densification that the territory needs if it is to house a population projected to reach 500,000 by 2040. Conversion of surplus office stock to residential — something inner-Melbourne and inner-Sydney are already pursuing — is technically possible in parts of Civic and Braddon, but ACT planning rules have historically made it difficult and expensive.

The immediate practical advice is simple. If you run a small business, the next six to twelve months represent an unusual window to lock in favourable commercial leases in central locations that would have been unaffordable three years ago. If you are a resident or ratepayer, pay attention to what the ACT Government does with its own leasing decisions when agency leases come up for renewal — those choices, made quietly in Treasury annexes and ministers' offices, will do more to determine the shape of central Canberra in 2035 than any planning blueprint.
