Western Sydney is the densest cluster in this dataset
Update, 13 November 2026: counts recalculated after the directory was expanded nationally, and again later the same day after further verified New South Wales projects were added. The first version counted 13 of 21 NSW listings.
Of the 43 New South Wales listings in the current directory, 15 sit in a tightly defined Western Sydney group: Horsley Park, Eastern Creek, Kemps Creek, Marsden Park, Wetherill Park, Erskine Park, and the AirTrunk SYD3 record whose suburb field is simply “Western Sydney”. That grouping is a reading of the suburb fields in this dataset, not an official planning-region extract. Several newer NSW listings sit outside this defined group, including records in Macquarie Park, Seven Hills, Mascot, Minchinbury, North Ryde and Jerrabomberra. Minchinbury is geographically in Western Sydney but is not one of the suburb labels used in this cluster.
The cluster is a mix of work already on site and very large proposals still in planning. Under construction in this group are NEXTDC S4 Phase 1 at Horsley Park, AirTrunk SYD3, the CDC Marsden Park campus, Lendlease’s Davis Road / Project Blue Tongue project at Wetherill Park, and DCI SYD02 at Eastern Creek. Five of the nine NSW projects recorded as under construction are in this group.
The planning end of the same geography includes some of the largest first-published capacity figures in New South Wales: the amended Mamre Road campus proposal at Kemps Creek (1.2 GW), NEXTDC S7 at Eastern Creek (612 MW in the SSD description, with the OpenAI arrangement recorded as a non-binding MoU only), STACK SYD01 at Erskine Park (up to 450 MW), and Stockland Aldington Road at Kemps Creek (up to 360 MW IT in the amended wording). Those figures are proposals or application numbers, not operating load. Goodman’s Project Atlas at Eastern Creek is also in planning, without a published MW figure in the compiled record.
Eastern Creek and Kemps Creek also hold operational or expansion listings (CDC Eastern Creek, Microsoft Kemps Creek) and an approved 35 MW record (Project Echidna). NEXTDC S4 Phase 2 at Horsley Park is in planning, with published investment figures that already differ between sources — the compiled record notes both A$1.79 billion and a portal snapshot of A$3.50 billion. That disagreement is left visible on purpose.
This is not a complete inventory of Western Sydney. It is a snapshot of what this compilation currently contains. Open the NSW project list or the individual records for the published wording and the date each row was checked (4 or 13 November 2026 in the current file).
