The transaction lifts AirTrunk’s total committed debt financing to approximately A$38.4bn ($26.9bn) globally, including over A$19.8bn across Australian assets.
Fourteen lead banks underwrote the debt facility.
The group comprises Banco Santander, BNP Paribas, Crédit Agricole Corporate and Investment Bank, DBS Bank, Deutsche Bank, ING Bank, Mizuho Bank, MUFG Bank, National Australia Bank, Royal Bank of Canada, Société Générale, Sumitomo Mitsui Banking, The Hongkong and Shanghai Banking, and United Overseas Bank.
Sumitomo Mitsui Banking, The Hongkong and Shanghai Banking, and United Overseas Bank acted as green loan coordinators.
Mallesons advised the borrower, while Gilbert & Tobin advised the lenders.
Structured with margin adjustments, the facility redirects margin savings into AirTrunk’s social impact programme to fund local initiatives across science, technology, engineering, and mathematics (STEM) education, digital equity, biodiversity, sustainable innovation, and disaster relief.
The project supports the company’s Net Zero 2030 emissions goals, employing lower-carbon concrete and steel, alongside a target to divert at least 90% of non-hazardous building waste from landfill.
The expanded campus will provide computing capacity for cloud, AI, and enterprise services, supporting over 10,000 jobs in construction, engineering, trades, logistics, and safety.
AirTrunk is utilising a 25,000m² Western Sydney staging facility for just-in-time equipment deliveries, supported by dedicated time-charter vessels shipping through Port Botany and Port Kembla.
AirTrunk origination and market expansion vice president Tom Mackellar said: “SYD3 is a long-term investment in Western Sydney and Australia’s digital capability, backed by the confidence of leading Australian and international banks.
“As the campus develops, it’s building a regional ecosystem through active hiring, sustained project activity and strategic supply chain partnerships – creating opportunities for local workers, contractors and businesses while delivering infrastructure Australians increasingly rely on.
“The green financing also reflects our view that sustainability should be built into how digital infrastructure is funded and delivered. We’re focused on responsible growth that creates lasting value for communities in the regions where we operate.”
AirTrunk holds five Australian data centre campuses representing over 1.2GW of capacity, having invested more than A$12bn locally with plans to deploy a further A$75bn over the coming decade.
In FY26, the company worked with 1,436 suppliers across Asia-Pacific (APAC), including 615 Australian firms accounting for A$3.4bn in activity.
