Data centres in Sydney
Australia's deepest data centre market, Macquarie Park's established cluster plus the fast-growing Western Sydney corridor around Eastern Creek and the Aerotropolis.
Indicative estimates · public sources
The Sydney market
Sydney is the country's primary data centre market and a major Asia-Pacific hub. Two clusters dominate: the mature Macquarie Park precinct in the north, dense with colocation and interconnection, and the Western Sydney corridor around Eastern Creek, Kemps Creek and the Aerotropolis, where land, zoning and large-load grid capacity are steering most new hyperscale build. International capacity and cloud demand land here first, which is why both operating capacity and the construction pipeline lead the nation (indicative). Sydney is Australia's largest data centre market and one of the Southern Hemisphere's biggest, with operators such as NEXTDC, Equinix Sydney, AirTrunk and CDC active across the metro. AI demand, the New South Wales government's digital agenda and rising data centre investment are pushing new megawatts toward Western Sydney, where developers weigh grid power, energy efficiency and recycled-water access alongside land.

What limits new data centre capacity in Sydney
Transmission headroom on Transgrid's 330 kV network around Western Sydney, not land, is the binding constraint on new Sydney capacity.
New large loads connect via Ausgrid, Endeavour Energy and Transgrid, with Western Sydney's transmission headroom a recurring constraint on how fast campuses can energise. Transgrid has reported data centre connection enquiries of about 14 GW within roughly 12 km of its Sydney West substation, and has warned that the existing 330 kV network around Western Sydney is close to fully committed, so new large loads increasingly have to fund network augmentation such as the proposed bulk supply point at Kemps Creek before they can connect. Sites pair grid connection with on-site backup and explore behind-the-meter options to bring capacity forward. Water for evaporative cooling is a live planning issue in the west, pushing newer designs toward air-cooled and closed-loop systems.

Data centre asset classes in Sydney
The asset types most relevant to the Sydney market right now.
Operating data centres
Income-producing colocation, hyperscale and edge facilities trading on yield and covenant.
AI data centre capacity
Capacity built to power and cool dense racks of accelerators, typically 50 to 150 kW per rack, with liquid cooling and a confirmed path to the power those racks demand.
Powered land
Industrial-zoned land with secured or in-progress grid connection. The connection is the asset.
