AirTrunk has secured a A$4.25 billion green loan to fund the continued development of its SYD3 campus in Western Sydney, as demand rises for data centre capacity to support cloud and artificial intelligence workloads.
The company said the SYD3 expansion would add infrastructure for cloud, AI and other digital services used by Australian businesses, governments and communities, and is expected to support more than 10,000 jobs across construction, trades, engineering, logistics and safety.
AirTrunk said the financing is structured as a green loan with margin adjustments, with any contributions from margin savings directed to its social impact program to support local charities across STEM education, digital equity, biodiversity and conservation, sustainable innovation and disaster relief.
In the release, AirTrunk said SYD3 is generating activity for contractors and suppliers across Western Sydney and Australia, including in steel and precast manufacturing, freight and logistics, civil works, and electrical and mechanical services.
AirTrunk reported that in FY26 it worked with 1,436 supplier entities across APAC, including 615 in Australia, accounting for A$3.4 billion in supplier activity.
The company said it is using a 25,000 sqm buffer zone in Western Sydney to store, stage and pre-commission data centre equipment to support just-in-time deliveries, and that it has invested in dedicated time-charter vessels to support supply chain flows into Port Botany and Port Kembla.
Tom Mackellar, Vice President, Origination & Market Expansion 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 said it will continue working with contractors, suppliers and community partners as the project progresses, and described workforce initiatives including apprenticeships, partnerships with vocational education providers and participation in a national skills advisory group.
According to the release, AirTrunk’s Australian platform spans five campuses with more than 1.2GW of capacity. The company said it has invested over A$12 billion across its Australian projects to date and plans to invest a further A$75 billion over the next decade.
AirTrunk said the latest deal brings its total committed debt financing to about A$38.4 billion globally, including more than A$19.8 billion across its Australian projects.
The company said the financing supports its Net Zero 2030 target for net zero Scope 1 and Scope 2 emissions by 2030, citing measures including energy efficiency, renewable energy matching and lower-carbon technologies, as well as reducing Scope 3 emissions through lower embodied carbon in new builds. For SYD3, it said construction measures include lower carbon steel and concrete and a target to divert at least 90 per cent of non-hazardous construction waste from landfill.
Construction of the expanded SYD3 development, led by A W Edwards, is underway, with completion expected by mid-2028.
