Highlights

  • Atlassian Central topped out in July 2026, according to Dexus.
  • The project is a 39-storey hybrid timber, steel and concrete office tower.
  • The structure stands more than 180 metres tall in Sydney.
  • Dexus targeted practical completion by the end of 2026.
  • An announced structural milestone is not the same as completed tenant occupation.

Dexus (ASX:DXS) is an Australian real estate group involved in property investment, development and funds management. One of its prominent development projects is Atlassian Central at Sydney’s Tech Central precinct, where construction reached the tower’s final structural level in 2026. That event establishes measurable progress towards completion, but does not establish that leasing targets, final occupancy approvals or tenant move-in arrangements have already been completed.

A documented construction milestone

In a company update dated 23 July 2026, Dexus said the Atlassian Central building had topped out, meaning it had reached its final structural level. The 39-storey office tower exceeds 180 metres in height and uses a hybrid structure combining mass timber with steel and concrete. Dexus described it as the world’s tallest hybrid timber tower. ASX:DXS also stated that work continued on the façade and central building services after the structural milestone.

The difference between topping out and practical completion matters. Reaching full structural height does not mean that all internal building systems, façade works and commissioning tasks are finished. The 2026 company update said the project remained on track for practical completion at the end of that year. It expressed a target rather than confirming that the building had been handed over. The verified construction update does not report a completed leasing campaign.

Development design and project partnership

Dexus identifies itself as developer and co-owner of Atlassian Central alongside Atlassian. The building has been designed to connect offices with Sydney’s innovation precinct and Central Station surroundings. Its hybrid building system uses timber to reduce structural weight and embodied carbon while retaining steel and concrete for critical strength requirements. ASX:DXS said Built, working with Obayashi Corporation in a joint venture, was engaged to lead construction.

The company reported environmental design ambitions, including a targeted 50 per cent reduction in upfront embodied carbon across the structure relative to a conventional premium commercial office tower. It also cited a targeted 50 per cent improvement in operational energy efficiency compared with a conventional 5 Star NABERS base building. These are design comparisons and targets, not verified final operating measurements. Readers should not interpret them as certification outcomes or realised utility savings.

What remains outside the confirmed update

The 23 July announcement did not establish that every regulatory sign-off, occupation certificate or workspace fit-out had been completed. Nor did it substantiate a precise number of new third-party tenants signed in 2026 or incremental funds management fees attributable to the project. ASX:DXS can report development progress without that progress immediately becoming rental earnings.

Construction delivery also requires building-service integration, finishing work and coordination among tenants and contractors. Describing these ordinary steps is different from alleging overruns or delays. The company’s statement that practical completion remained targeted for the end of 2026 is the verified time reference. An exact final handover date would need a later company announcement.

How the development fits the portfolio

Dexus lists Atlassian Central among its developments under construction and identifies it as an office project completing in 2026. It remains categorised as a development project. ASX:DXS also manages a broader real estate portfolio, meaning consolidated performance cannot be attributed to a single project without supporting financial disclosures.

The verified focus is therefore construction sequencing and eventual completion, not a purportedly concluded leasing campaign. The next meaningful disclosures would be confirmation of practical completion, any subsequently reported leasing details and their treatment in Dexus’s financial reports.

Key Insights

Dexus (ASX:DXS) reached a defined construction stage at Atlassian Central in July 2026. The tower’s structural completion and the remaining façade and services work are supported by the company’s dated update. Practical completion was targeted for late 2026, while final occupation, leasing figures and income effects were not established by that announcement.
