Australian data centre operator AirTrunk has unveiled plans to build two hyperscale facilities in Johor Bahru, Malaysia, with an investment of RM12bn ($3bn).
The two campuses, designated JHB3 and JHB4, will be in Iskandar Puteri, Johor, adjacent to the company’s existing JHB1 and JHB2 sites.

Between them, the new facilities are expected to deliver more than 280MW of IT load capacity.
With the addition of JHB3 and JHB4, AirTrunk’s Malaysian portfolio will span four campuses with a combined capacity exceeding 700MW.
The company said its total committed investment in the country now stands at approximately RM27bn ($6.8bn).
AirTrunk’s existing Malaysian campuses are approaching full capacity.
JHB1 and JHB2, which together account for more than 420MW of IT load, are described as almost fully contracted.
JHB2 was announced in early 2025.
The new campuses are designed to accommodate high-density cloud and AI workloads.
AirTrunk said both sites will incorporate advanced cooling infrastructure operating on 100% recycled water and will achieve lower power usage effectiveness ratings than those typical of conventional data centres.
Once JHB3 and JHB4 are operational, AirTrunk said its total operating and planned capacity across 22 campuses in six markets – Australia, Singapore, Japan, Malaysia, Hong Kong, and India – will surpass 3.3GW.
The development is expected to generate more than 3,000 construction jobs, with further employment anticipated once the campuses are in operation.
AirTrunk said it has already awarded RM423m ($106.5m) in contracts to Malaysian suppliers, a figure it expects to rise to RM5bn ($1.26bn) upon completion of all four campuses.
AirTrunk founder and CEO Robin Khuda said: “JHB3 and JHB4 represent the next phase of our expansion in Malaysia, building on the strong momentum of our existing Johor platform.
“Malaysia has set a clear ambition to lead in AI, and we are investing in that vision for the long term, both within Johor and across the country in time.”
The Johor Bahru expansion comes alongside AirTrunk’s separately announced move into India, where the company has indicated a near-term investment of more than $5bn.
