Canberra's Office Market Is Splitting in Two — Here's What Businesses Need to Know Right Now

Vacancy rates across Canberra's commercial office market tell two very different stories depending on which building you're standing in. Premium A-grade space in the city core is running at vacancy rates below 7 percent, while B and C-grade stock in fringe suburbs is sitting closer to 18 percent — a bifurcation that is reshaping lease negotiations, fitout budgets and location decisions for businesses across the ACT right now.

The timing matters because several forces are converging at once. The federal government's ongoing Property Consolidation Program, which is pulling Commonwealth agencies out of ageing leased buildings and into government-owned or purpose-built facilities, is compressing demand for older stock at the exact moment that national AI datacentre investment is driving industrial land values higher and crowding out some commercial development pipelines. Businesses that signed five-year leases in 2021 are hitting renewal decisions in a market that looks nothing like the one they entered.

Where the Pressure Is Building

Civic and the Barton precinct are the pressure points. On London Circuit, several buildings completed since 2022 are reporting near-full occupancy, with effective rents for premium space pushing past $520 per square metre net annually — up from around $470 per square metre in mid-2024. Landlords in those buildings are offering fitout incentives of between 10 and 14 months on a five-year deal, which sounds generous but is notably less than the 16 to 18 months that was common twelve months ago. The incentive pool is shrinking because landlords no longer need to compete as hard.

Meanwhile, Fyshwick and the older parts of Woden are a different picture. Former government-tenanted buildings along Callam Street in Woden have struggled to backfill space vacated when the Department of Social Services consolidated operations closer to the Parliamentary Triangle in 2025. Those buildings are offering incentives well above 20 months but still finding limited traction, particularly from private sector tenants unwilling to invest in the infrastructure upgrades those older buildings require to meet contemporary energy and connectivity standards.

The National Australian Built Environment Rating System, known as NABERS, is no longer just a sustainability badge. Tenants with any ESG reporting obligations — and that now includes most ASX-listed firms with ACT operations, as well as a growing number of government contractors — are treating a NABERS Energy rating below 4.5 stars as a dealbreaker. Buildings that cannot achieve that threshold are effectively being locked out of a significant slice of the tenant pool.

What Businesses Should Do Before Signing Anything

For tenants with leases expiring before the end of 2027, the advice from commercial agents operating in Canberra's market is consistent: start conversations at least 18 months out, not 12. In a tightening A-grade market, the leverage window closes quickly once a landlord has competing interest. The Australian Capital Territory's Land Development Agency has flagged two new mixed-use commercial sites in Dickson and Molonglo Valley for release in the 2026–27 financial year, which will eventually add supply, but nothing that will settle into the leasing market before late 2028 at the earliest.

Businesses that can genuinely function in B-grade space should look hard at the Woden and Belconnen CBDs, where effective rents can be 25 to 30 percent lower than Civic equivalents and landlords are doing deals. The ACT Government's Suburban Business District Strategy, released in March 2026, is also worth reading — it outlines infrastructure and planning commitments designed to make those precincts more attractive, and some of those commitments include transport links that will be material to staff amenity calculations.

The bottom line for any Canberra business reassessing its property position right now: the market is not uniform, leverage is highly location-dependent, and the decisions made in the next six months will lock in costs for half a decade. Get independent advice, run the NABERS numbers, and do not assume that what your current landlord is offering reflects what the building next door would accept.
