At a glance
Data centre projects account for A$14.2 billion of the A$31.1 billion in private investment lodged across the Western Sydney airport city, on the Bradfield Development Authority’s June 2026 figures.
Ten of the 15 data centre projects backed by the NSW Investment Delivery Authority sit in Western Sydney councils, spanning Blacktown, Penrith, Fairfield and The Hills.
Roughly a third of the 87 Sydney data centre sites in the Australia Data Centre Index sit in Greater Western Sydney, clustered at Eastern Creek, Erskine Park, Huntingwood and Kemps Creek.
Eleven Western Sydney facilities across six operators hold the Australian Government’s HCF Certified Strategic status, the marker of eligibility to host sensitive government and regulated workloads.
Grid capacity decides how much of the pipeline actually gets built, and Transgrid’s Sydney Ring South is the transmission project the region is waiting on.
Why the west
Western Sydney holds close to a third of the NSW population, and the state has been clear that it will carry most of the state’s growth. The Western Sydney International Airport starts commercial flights in November 2026, and the 11,200-hectare airport city and the Bradfield City Centre around it have pulled in private capital at a scale the region has not seen before.
Data centres are the newest wave. The Bradfield Development Authority reports that development applications in the airport city are worth A$31.1 billion of private investment, of which A$14.2 billion is data centres. That data centre figure now sits inside a private-investment total that has overtaken the A$28 billion of government infrastructure spending on the airport, its metro and surrounding roads. The pull is low latency to Sydney’s population and access to land and power at a scale the established northern and inner corridors cannot match. Global operators treat the west as a core availability zone. Business Western Sydney, the regional business body, calls the data centre wave a positive for the region while flagging power and water as issues to work through responsibly.
Who is building where
The Australia Data Centre Index tracks 87 operational and announced data centre sites across Sydney. Around 30 of them sit in Greater Western Sydney, concentrated in a handful of council areas. Blacktown carries the largest cluster, at Eastern Creek and Huntingwood. Penrith holds the Erskine Park cluster. Fairfield, Cumberland, Parramatta and The Hills each hold facilities of their own.
The named operators already on the ground include AirTrunk at Huntingwood, Canberra Data Centres and DCI Data Centers at Eastern Creek, Digital Realty at Erskine Park, and Microsoft at Kemps Creek. Amazon Web Services runs its William Dean campus at Eastern Creek and a further campus at Smeaton Grange. The full site-by-site view sits on the Sydney data centre infrastructure map, which tracks a 5.2 GW pipeline and A$51.9 billion of Investment Delivery Authority-endorsed investment across Greater Sydney.
The certified cluster: what carries HCF status
The dimension that separates a certified facility from a listed one is the Australian Government’s Hosting Certification Framework. Eleven Western Sydney facilities across six operators hold HCF Certified Strategic status, the tier that lets a facility host sensitive government and regulated data. They split into five Strategic Facilities and six Strategic Enclaves.
Operator | Certified site(s) | Suburb (council) | Certification | Power band |
AirTrunk | SYD1 | Huntingwood (Blacktown) | Strategic Facility | Hyperscale |
Canberra Data Centres | EC1–EC4 | Eastern Creek (Blacktown) | Strategic Facility | Hyperscale |
DCI Data Centers | SYD-01 | Eastern Creek (Blacktown) | Strategic Enclave | Hyperscale |
Digital Realty | SYD10, SYD11, SYD14 | Erskine Park (Penrith) | Strategic Enclave | Hyperscale |
Equinix | SY6 | Silverwater (Parramatta) | Strategic Enclave | Enterprise |
Fujitsu | Western Sydney | Pemulwuy (Cumberland) | Strategic Enclave | Wholesale |

Certification is a procurement qualification. A facility needs it before a government agency or a regulated enterprise can place a workload there, so the certified cluster is the part of the Western Sydney map that shows where sovereign and regulated demand can land. The live certification status for every site sits in the directory of certified data centres, which currently records 59 HCF Certified Strategic facilities nationally out of 208 tracked sites.
The pipeline still to be built
Beyond the operating cluster, the Investment Delivery Authority is backing 15 data centre projects across NSW, and ten of them sit in Western Sydney councils. NEXTDC is supported for its S4 facility at Fairfield and S7 at Eastern Creek. Stockland won backing for three projects. GreenSquareDC’s SYD1 has a 96 MW AI data centre endorsed for Western Sydney, and the Mamre Road precinct continues to draw both logistics and digital infrastructure. Several of these are the kind of AI data centre built for inference workloads that need to sit close to the users they serve.
Announced capacity and built capacity are different things. As we set out in our coverage of Transgrid’s position on funding NSW grid capacity, not every proponent will secure the connection they need, and headline connection requests can overstate genuine demand. AEMO’s Integrated System Plan work treats a share of registered connection interest as duplicate or speculative, so the pipeline figure and the load that finally draws on the grid are different numbers.
Power is the gating item
The constraint on Western Sydney’s build-out is electricity and the transmission to move it. The west has land and power headroom the inner corridors lack, but delivering that power still depends on new transmission. Transgrid’s Sydney Ring South project is the piece of infrastructure the region is waiting on, because it strengthens the network into south-western Sydney and can carry renewable generation from regional NSW and interstate toward households and facilities alike. Data Centres Australia argues the build-out and the energy transition can advance together rather than compete, and NEXTDC frames the requirement as coordinated investment across digital and energy infrastructure.
The NSW government has said it will set the parameters for approval, including power and water requirements, and the absence of a standalone state data centre strategy was raised at a recent parliamentary inquiry. Our analysis of the NSW data centre consultation paper sets out the five principles the state has signalled will shape approvals through the next decade.
The jobs the build creates
The employment case runs in two stages. Data Centres Australia describes it as construction and trade jobs first, building the shells, electrical plant and cooling, then a skilled operations and networking workforce that lasts the life of the facility. The Bradfield Development Authority makes a related point about the type of jobs rather than only the volume: the enterprise precinct it has opened for expressions of interest is drawing defence, aerospace and advanced manufacturing alongside high-tech data centre roles. Both stages matter, and the operations roles are the higher-value, longer-duration ones.
The sector-wide shortage is real. Australia faces a shortfall of skilled data centre workers running into the thousands by 2030, which is the backdrop to our reporting on Australia’s 2026 data centre hiring landscape. Current openings across operators and adjacent sectors are listed on the Certified Strategic data centre jobs board.
What to watch
Three markers will show whether the Western Sydney pipeline converts. The airport opens to commercial flights in November 2026, the event the airport city’s investment case is timed around. The Investment Delivery Authority’s 15 backed projects will move at different speeds, and the ones that reach financial close will separate committed capacity from announced intent. And the NSW planning parameters for power and water, once set, will decide how much of the A$14.2 billion actually clears approval. Grid connection remains the binding item across all three.
