AirTrunk, an Australian data centre operator, has announced plans to invest $3 billion in building two new hyperscale data centres in Malaysia, signalling a major push to expand its footprint in Southeast Asia’s fast-growing digital infrastructure market. The new facilities will be in Johor Bahru, a region increasingly emerging as a strategic hub for data centre development due to its proximity to Singapore and strong connectivity advantages.
The two upcoming campuses, referred to as JHB3 and JHB4, will add more than 280 megawatts of combined IT capacity and will be situated near the company’s existing sites in the region. With this expansion, AirTrunk will operate four data centre campuses in Malaysia, taking its total capacity in the country to over 700 megawatts. This move effectively doubles the company’s local presence and reinforces its long-term commitment to the Malaysian market.
The investment will also raise AirTrunk’s total committed capital in Malaysia to approximately $6.8 billion, making the country one of its most significant markets globally. The new facilities are designed to support high-density cloud computing and artificial intelligence workloads, reflecting the rapid increase in demand for digital infrastructure across the Asia-Pacific region. Advanced cooling systems using recycled water and energy-efficient designs are expected to be incorporated to reduce environmental impact.
The expansion comes at a time when demand for cloud and AI infrastructure is accelerating faster than expected, driven by increased digital adoption and enterprise reliance on advanced computing technologies. AirTrunk’s leadership has emphasized the need to stay ahead of this demand by scaling infrastructure not only in Malaysia but across the broader region. The company is backed by a consortium led by Blackstone, which has been actively supporting its aggressive growth strategy.
This development is part of AirTrunk’s broader regional expansion plans, which include recent moves into India through the acquisition of Lumina CloudInfra. As competition intensifies in the global data centre market, the company is positioning itself as a key player in enabling next-generation technologies, particularly artificial intelligence. The Malaysia investment highlights how Southeast Asia is becoming a critical battleground for digital infrastructure providers seeking to capture the next wave of tech-driven growth.
