AirTrunk has been named the potential buyer for a $3.3 billion data center campus planned for Western Sydney, Australia. The Blackstone-owned firm is set to purchase the site which is being developed by property investor ISTP. However, this all depends on whether planning permission is granted for the data center project. Sources shedding light on the project have noted that preliminary agreement is in place between the parties. As reported by DCD, project management firm Plan Project Management filed a SEARS application with the New South Wales Government.
The application was for the Mamre Road Data Centre Campus in September. It is located at 706-752 Mamre Road in the Kemps Creek area of Sydney. The $3.3 billion (AU$5 billion) project is described as a 1GW data campus totaling six four-story data center buildings. Furthermore, the project spans 400,000 sqm (4.3 million sq ft). The site is also described as having a capacity from 600MW up to 1GW across 24 data halls.

Scope of Implementation on the AirTrunk Data Center Campus in Australia

The AirTrunk data center campus in Australia is expected to host various amenities to ensure its operations. It includes 936 cooling units and 852 diesel back-up generators. Documents also suggest the site would feature 7,488 cabinets for lithium-ion battery storage. TFurthermore, at least one on-site substation is planned and the potential for three others. The innovative approach facilitates in solving the power demand challenges facing data center developments in 2025.
Australian real estate firm ISPT lists 706-752 Mamre Road on its website as Summit. It is a 52-hectare land holding master planned for 245,000 sqm (2.6 million sq ft) of industrial floor space. Construction forecast on the project sets its commencement in early 2026. Conversely, the company acquired the site in July 2024 via its ISPT Core Fund. AirTrunk has data center campuses in operation and development in Sydney (x3), and Melbourne in Australia. It also has data center campuses in Singapore, Malaysia and two in Tokyo. Furthermore, there is one more in Osaka, Japan.
