Premium office space drives sharp rental surge across Australia’s CBDs
Office rents in Sydney, Melbourne and Brisbane are climbing at their fastest pace since the pandemic as tenants compete for premium CBD space amid tightening supply.

Australia’s major CBD office markets are recording some of their strongest rental growth since the pandemic, with businesses increasingly prioritising premium office space despite elevated geopolitical and economic uncertainty.
Knight Frank’s Australian Office Indicators Q1 2026 report found net effective rents in Sydney and Melbourne CBDs rose at their fastest annual pace since COVID-19, increasing 10.2 per cent and 6.8 per cent respectively over the 12 months to March.
Brisbane posted the strongest growth nationally, with net effective rents climbing 11.7 per cent over the same period.
The report points to a widening divide between prime CBD office towers and secondary office stock, as occupiers increasingly focus on quality, location and workplace amenity when making leasing decisions.
Knight Frank Senior Economist, Research & Consulting Alistair Read said demand remained heavily concentrated in premium assets within core CBD precincts, helping drive stronger rental growth in top-tier buildings.
“Occupier demand continues to be heavily concentrated in the most desirable CBD precincts and the highest-quality buildings, accelerating a sharp divergence between core and non-core markets,” Mr Read said.
According to the report, Sydney’s Core precinct and Melbourne’s Eastern Core significantly outperformed broader CBD markets over the past year.
“In Sydney’s Core precinct and Melbourne’s Eastern Core, net effective rents surged 14.3% and 16.1% over the past year, significantly outperforming the rest-of-CBD precincts,” Mr Read said.
The rental gap between prime and non-prime office locations has also continued to widen sharply.
“As a result, core CBD rents are now 54% higher than non-core locations in Sydney and 93% higher in Melbourne, highlighting the growing premium placed on amenity, accessibility and workplace quality,” he said.
Knight Frank said the strong rental growth across the major CBDs was being underpinned by a limited supply pipeline, with few new office developments expected to be delivered in the near term.
Mr Read said subdued construction activity was likely to support ongoing rental growth and tighter vacancy rates over the medium term, particularly for premium office towers.
“The combination of sustained demand and declining levels of new development will aid ongoing prime rental growth and lower vacancy rates over the medium term, particularly for best-in-class assets,” he said.
The report noted that current economic conditions were making new office developments increasingly difficult to justify financially.
“Economic rents remain well above expected market rents, making the construction of new office towers largely unviable, and concentrating tenant demand into existing buildings,” Mr Read said.
While suburban office markets generally remained subdued compared with CBDs, Melbourne’s Southbank precinct was identified as a relative outperformer, recording annual net effective rental growth of 2.7 per cent.
The report comes as broader Asia-Pacific office markets continue to stabilise following several years of disruption linked to hybrid work trends, inflation and rising interest rates.
Knight Frank’s separate Asia-Pacific Q1 2026 Office Highlights report found Sydney and Brisbane were among the strongest-performing office rental markets in the region, behind only Bengaluru and Tokyo for annual prime net face rental growth.
The Asia-Pacific report also found 18 of the 24 cities monitored across the region recorded stable or increasing rents in the first quarter of 2026, even as geopolitical uncertainty intensified following escalating conflict in the Middle East.

Mirvac’s 45-level Trielle has topped out at Yarra’s Edge, pairing riverfront apartments with wellness facilities, private dining and resident services.

Mirvac has topped out Trielle at Melbourne’s Yarra’s Edge, with more than 70 per cent of the riverfront development sold and approximately 80 per cent of purchasers intending to make their apartment a home.
The figures, released on September 22, point to an owner-occupier audience for one of the precinct’s final residential towers. Mirvac began developing Yarra’s Edge in 2003, and its latest addition occupies one of the remaining absolute riverfront sites.
Mirvac CEO of Development Stuart Penklis said existing residents were among those moving up within the neighbourhood.
“Many purchasers already have a connection to Yarra’s Edge,” Mr Penklis said, describing buyers whose changing needs were encouraging an upgrade within the precinct.
“As one of the final residential towers within Yarra’s Edge, Trielle represents the culmination of more than two decades of creating one of Melbourne’s most established and sought-after waterfront communities,” Penklis said.
“Positioned on the Collins Street axis with absolute river frontage, Trielle offers residents a rare opportunity to enjoy sweeping views across the Yarra River, Melbourne skyline and Port Phillip Bay, while remaining seamlessly connected to the CBD. With Trielle now more than 70 per cent sold, we’re continuing to see strong demand from buyers seeking quality homes in established locations.”
The developer also flagged a penthouse and sub-penthouse collection with larger layouts, premium finishes and broad outlooks. The planned wellness centrepiece, The Oasis, encompasses a 900-square-metre elevated urban rainforest.
Mirvac General Manager Residential Development Victoria Elysa Anderson said Trielle had resonated strongly with buyers seeking a rare lifestyle offering in Melbourne.
“Opportunities to secure a new luxury residence on a riverfront site of this calibre are incredibly rare, particularly within a community like Yarra’s Edge,” Anderson said.
“What makes Trielle unique is the combination of exceptional views, world-class residential facilities and the lifestyle that already exists around it. Residents are buying into a mature waterfront community with parks, promenades, dining, wellness and strong community connections already in place.”
The 45-level tower brings a substantial new presence to that waterfront. Its residential offering spans one-, two-, three- and four-bedroom apartments, with Signature, Prestige and Sub-Penthouse collections accommodating different household sizes. The north-facing position connects the apartments visually to the river and city beyond.
Seven storeys above the promenade, the planned Oasis combines planting and a running stream with a Scandinavian-inspired wellness club developed with spa specialist Naomi Gregory. Facilities include a 25-metre lap pool, hot magnesium pool, sauna, hydrotherapy, a gym, yoga and Pilates room, and treatment spaces.
The amenity extends beyond exercise. Residents will have access to The Biblioteca library and workspaces, ground-floor work pods, and The Salone piano lounge. A private Chef’s Table dining room offers a setting for larger gatherings, while a cinema, games room and sports lounge broaden the entertaining options. Concierge services and a dog-wash area support everyday routines.
Trielle comprises a collection of one, two, three and four-bedroom residences. Reflecting strong demand from owner occupiers, approximately 80 per cent of purchasers to date intend to live in their homes, highlighting the project’s appeal to those seeking a long-term waterfront lifestyle.
Mirvac has recently delivered The Albertine, a premium apartment development on the edge of Melbourne’s CBD, and is nearing completion of Prince & Parade in Brunswick, further strengthening its portfolio of thoughtfully designed apartment communities in some of Melbourne’s most sought-after urban locations.
