Viridis Green Data Centres has secured a site in Sydney for a new high-security edge data centre, marking its second confirmed Australian development as it builds out a network of Zone 4 facilities. The company said it has reached a heads of agreement for a site located within 15km of the Sydney CBD, with construction targeted to begin before the end of 2026 and commissioning expected in late 2027.
The proposed facility will be a Tier III, Zone 4 edge data centre, designed to support government, defence, and enterprise workloads requiring high levels of security. The Sydney development will be delivered within an existing structure, reflecting a similar approach to the company’s recently approved project in Burnie, Tasmania, where a commercial building is being repurposed into a secure data centre facility.
Specifications for the Sydney site include a hardened perimeter, modular Zone 4 pods capable of handling classified workloads up to Secret level under Australia’s Protective Security Policy Framework, and full redundancy across power and cooling systems.
The site is expected to draw around 0.8MW from the grid, with plans to expand power availability to support future capacity growth. “Securing the Sydney site is yet another significant milestone for Viridis,” said Michael Bull, managing director of Viridis Green Data Centres. “We are confident that the establishment of a Tier III, Zone 4 edge data centre in such a central location will provide Viridis with a highly sought after and unique data centre asset.”
Expanding sovereign edge footprint
The Sydney project follows planning approval for Viridis’s Burnie facility earlier this month, which is targeting a 2027 go-live and will serve as the only data centre of its type in North-West Tasmania. Together, the developments form part of Viridis’s broader strategy to deploy decentralised, high-security infrastructure, targeting locations where proximity, sovereignty, and resilience are key requirements.
The company is also progressing additional sites in Townsville and has positioned its platform around delivering modular, defence-grade data centres supported by clean energy systems. Viridis is working with its wholly owned subsidiary, Oper8 Global, to finalise the design and build of the Sydney facility, with an estimated contract value of around AUD 8 million. The company said it is already in early discussions with potential customers.
