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

Sydney's commercial property market has entered a decisive phase. Vacancy rates across the CBD's premium A-grade stock have dropped to around 8.2 per cent as of mid-2026, while B-grade and suburban offices are sitting closer to 18 per cent — a bifurcation that property analysts say is now structural, not cyclical.

The timing matters. A confluence of pressures — AI data centre developers competing aggressively for industrial-zoned land on the city's western fringe, a federal budget that hammered investor confidence in residential property, and a hybrid work market that has finally stabilised at roughly three days in the office per week — has forced commercial tenants and landlords alike to make decisions they had been deferring since 2022.

Where the Action Is — and Where It Isn't

In the CBD core, towers along Martin Place and the western corridor of George Street are commanding net face rents of between $1,150 and $1,350 per square metre per annum for premium floors. Mirvac's 55 Pitt Street development, which reached practical completion in late 2025, has leased approximately 70 per cent of its net lettable area, according to industry sources familiar with the building. That rate of take-up, achieved during what most agents describe as a cautious market, underscores how fiercely tenants are competing for new, well-serviced stock.

The story in North Sydney is more complicated. The suburb absorbed a wave of new supply in 2024 and early 2025, and while anchor tenants have filled the flagship towers on Miller Street, secondary buildings within 400 metres of the Victoria Cross metro station are still offering incentive packages worth 30 to 35 per cent of the total lease value — free rent periods, fit-out contributions, or both. That is a generous number by any pre-pandemic standard.

Parramatta tells a different story again. The western CBD, which state government bodies treated as a growth priority through the early 2020s, has seen several planned commercial developments stall. Land that might have become office towers near Church Street is now the subject of competing interest from data centre operators who need the power infrastructure and zoning flexibility that industrial corridors near the M7 can provide. The competition is real: one parcel near the Rosehill area received unsolicited approaches from two separate hyperscale operators in the first quarter of 2026, according to a property advisory firm that worked on the transaction.

What Tenants and Landlords Should Do Before Year-End

For businesses with leases expiring in the next 18 months, the leverage sits firmly with the tenant — but only if they know which market they are negotiating in. A financial services firm renewing in a B-grade Clarence Street building has considerably more bargaining power today than the same firm would have had in 2019. The same firm looking at a half-floor in a Barangaroo tower will find a landlord far less willing to move on headline rent, even if incentives remain available.

The landlord community is not uniformly stressed. The listed real estate investment trusts with heavy weighting toward premium CBD assets — GPT Group and Dexus among them — have largely marked their books to reflect the new rate environment and are working through lease expiries methodically. The pain is concentrated in unlisted syndicates and private owners holding secondary stock in locations that never fully recovered foot traffic after 2020.

Two practical realities demand attention before the end of 2026. First, AI-driven tenant demand for ultra-low-latency office connectivity is starting to influence fitout specifications in ways that older buildings simply cannot meet without significant capital expenditure. Second, the Albanese government's expanded workplace tax arrangements, confirmed in the May budget, will affect how businesses structure their physical footprint from July 1 next year. Tenants who wait until their lease expires to think about this will be making the decision under pressure. The businesses getting the best outcomes right now are the ones treating their office commitment as a strategic question, not an administrative one.
