Atlassian Central is a landmark sustainable development in Sydney, Australia, and the tallest hybrid timber skyscraper in Oceania. Located above Sydney's Central Station, the project is being developed by Dexus in partnership with Atlassian as the software company's future global headquarters and a centerpiece of the city's Tech Central innovation precinct. What makes the building exceptional is its hybrid structural system, which combines mass timber, steel, and reinforced concrete to achieve the strength required for a high-rise while significantly reducing embodied carbon compared with conventional construction.

The building features a reinforced concrete core, an external steel exoskeleton, and large engineered timber floor panels and columns, demonstrating how sustainable materials can be successfully incorporated into modern skyscraper design.

A major milestone was achieved on 22 July 2026, when the project officially topped out, marking the completion of its highest structural level. The topping-out ceremony celebrated not only the project's progress but also Australia's growing leadership in large-scale timber construction. The tower is expected to be completed by the end of 2026 before entering its final commissioning phase.

Beyond its record-breaking height, Atlassian Central has been designed to create a healthier and more sustainable workplace. The building incorporates natural ventilation, high-performance façades, generous green spaces, and multi-level "habitats" that encourage collaboration while improving energy efficiency and occupant wellbeing. As one of the world's most ambitious timber high-rises, Atlassian Central represents a significant step forward in environmentally responsible architecture and is expected to influence the future of sustainable skyscraper construction worldwide.
