Scope and capacity

On October 27, 2026, AirTrunk announced an A$4.25 billion green loan for continued SYD3 development. Contractor reporting also confirms expanded construction with completion forecast for mid-2028; financing and construction do not establish that the campus's full planned capacity is operating. AirTrunk is developing SYD3 as a 400-plus-MW hyperscale campus in Western Sydney. The nine-phase site remains under construction and is designed to extend the company's connected Western Sydney platform. AirTrunk is publicly identified in the project record for Western Sydney, NSW, AU. The disclosed development record includes more than 400 MW planned campus capacity; approximately 20.5 acres; 42 data halls; dedicated 132 kV high-voltage feed. Power and infrastructure include nine-phase campus with an onsite 132 kV substation and shared regional connectivity to SYD1. AirTrunk currently describes SYD3 as a 400-plus-MW hyperscale campus at full development.
