AirTrunk Secures $3 Billion Green Loan for SYD3 Campus

AirTrunk has secured a A$4.25 billion green loan to fund its SYD3 hyperscale data centre campus in Western Sydney. The financing was provided by a consortium of 32 local and international financial institutions, underscoring robust investor appetite for large-scale, sustainable digital infrastructure.

The green loan was underwritten by 14 lead banks. This group includes Banco Santander, BNP Paribas, Crédit Agricole Corporate and Investment Bank, DBS Bank, Deutsche Bank, ING, Mizuho Bank, MUFG Bank, National Australia Bank, Royal Bank of Canada, Société Générale, Sumitomo Mitsui Banking Corporation, HSBC, and United Overseas Bank. Sumitomo Mitsui Banking Corporation, HSBC and UOB acted as green loan coordinators.

Project Scale and Impact

The SYD3 campus is set on 8.3 hectares in Huntingwood, about 30 kilometres west of central Sydney. At full build-out, it will deliver 400 megawatts of capacity across 42 data halls and 70,000 square metres of technical space. Construction is underway and completion is expected by mid-2028.

The project is likely to support more than 10,000 jobs across construction, trades, engineering, logistics and safety. It will add secure and resilient infrastructure for cloud computing, artificial intelligence, and other digital services. AirTrunk's Australian platform now spans five campuses with more than 1.2 gigawatts of total capacity.

Financing Context and Scale

The new facility extends AirTrunk's total committed debt financing to approximately A$38.4 billion globally. Over A$19.8 billion of this is allocated to the company's Australian projects. The SYD3 loan is about 27 percent larger than the financing arranged for AirTrunk's JHB2 facility in Malaysia's Johor state earlier this year.

This deal continues a run of bank financing since Blackstone and CPP Investments agreed to buy AirTrunk in 2024. The final loan size came in just below the A$4.3 billion facility the company was reported to be negotiating in June. The financing arrives despite growing investor caution around capital-intensive AI infrastructure projects, a trend that has seen other operators shelve development plans and IPO ambitions.

Tom Mackellar, AirTrunk's Managing Director and Co-Head of Asia Pacific, 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."

Sustainability and Social Commitment

The green loan incorporates strict environmental standards. It requires construction measures such as using lower-carbon steel and concrete and diverting at least 90 percent of non-hazardous construction waste from landfill. The financing also includes margin adjustments.

Contributions from these margin savings will be directed to AirTrunk’s social impact program. This initiative supports local charities working across STEM education, digital equity, biodiversity and conservation, sustainable innovation, and disaster relief. Robin Khuda, AirTrunk's Founder and CEO, described the successful fundraising as evidence of "a flight to quality in an increasingly selective capital market."

The company has invested more than A$12 billion in Australia to date and plans to invest a further A$75 billion over the next decade. Construction of the expanded SYD3 development is underway, with completion expected by mid-2028.
