Sydney CBD Office Vacancy Tightens as Premium Space Shrinks Through 2026

Sydney’s CBD office market entered 2026 with overall vacancy sitting at 13.8%, yet beneath that headline figure a clear flight to quality is reshaping the city’s commercial core. Premium-grade vacancy has tightened to between 8.9% and 9.8%, according to Cushman & Wakefield’s latest Sydney MarketBeat report, as tenants compete for the best space in a market that will see no new supply this year.

Flight to Quality Drives Premium Absorption

The divergence between overall and premium vacancy reflects a structural shift underway in the CBD, stretching from Martin Place to Barangaroo. Net absorption remained positive at 11,359 sqm over the past six months, a sign that underlying demand is gradually improving even as the aggregate vacancy rate stayed high due to earlier waves of new construction. Tenants are voting with their feet for assets offering modern floorplates, end-of-trip facilities and sustainability credentials, leaving older B- and C-grade towers to contend with softer leasing conditions.

Rents are responding. Prime-grade net effective rents rose 3.7% year-on-year to $912 per sqm per annum at the end of Q1 2026, while A-grade space climbed 5.2% to $747 per sqm per annum, data from Cushman & Wakefield’s Q1 2026 report shows. The upward trajectory in top-quality rents, even as the broader market absorbs excess supply, underscores the premium tenants are prepared to pay for buildings that meet evolving workplace and sustainability standards.

Supply Pause Favours Landlords

No new CBD office completions are expected in 2026, with only limited supply scheduled to arrive in 2027, according to market intelligence from Hanley Capital and Cushman & Wakefield. That pause in new deliveries, following several years of elevated construction, is expected to support further rental growth in premium and A-grade towers, where vacancy is already at or near single-digit levels.

The supply hiatus comes at a time when investors are pricing in renewed caution. Sydney CBD office yields softened to 5.77% in Q1 2026, up 27 basis points from late 2025, reflecting higher interest rate expectations and a more cautious capital market. The yield shift suggests buyers are demanding a greater risk premium, even as leasing fundamentals in the best buildings show real momentum.

What’s Next for the Sydney CBD Office Market

For occupiers, the window for securing premium-grade space at today's rents looks set to narrow through the second half of the year, particularly as no new buildings open to relieve tight conditions in the top tier. Landlords of well-located, modern assets in areas such as Circular Quay and Darling Harbour are likely to hold pricing power, while owners of older stock will face continued pressure to invest in upgrades or repositioning to compete.

Investors will be watching interest rates closely. If the Reserve Bank holds or raises rates, further yield decompression in the office sector could follow, particularly for secondary assets. But for those able to deploy capital into premium-grade product, the combination of tightening vacancy, rising rents and a clear supply gap makes the CBD’s top tier one of the more compelling property stories in the country right now.
