This directory lists the companies building, owning, operating, financing and supplying Australian data centres, grouped by the role each one plays. Every company appears because of a public, verifiable connection to an Australian data centre facility or project, and that connection is shown next to the company.
There is no ranking. Size, capacity and project involvement are shown where they are publicly disclosed, so you can compare companies on facts.

How the Australian data centre industry fits together
A single campus usually involves at least six types of company:
- A developer secures land, power and planning approval.
- An investor or owner funds it.
- An operator runs it. This is often the same company as the developer.
- Tenants (cloud providers, AI companies, enterprises, government) lease capacity.
- A head contractor and engineering consultants design and build it, with dozens of trade subcontractors.
- Energy and network companies connect and supply it.
Knowing which company holds which role on a project tells suppliers who actually makes purchasing decisions.

Is your company missing?
We add companies when there is a verifiable, public link to an Australian data centre facility or project. If your company has one, submit it with a source (a project page, case study, media release or planning document).
Selling to Australian Data Centre Companies?
Knowing who the companies are is the first step. Reaching the people inside them who choose suppliers is the harder one. AISB helps suppliers build target account lists across operators, developers and head contractors, and stay visible to them through planning and procurement.
Sources & Verification
Sources are linked beside each entry. Operator facility details come from each operator's own website, checked 27 September 2026. Planning references come from the NSW Planning Portal.
