AirTrunk SYD3 Hyperscale Data Center Campus
Status: Phased Construction/Expansion (Operational and scaling) | Location: Western Sydney, New South Wales (Huntingwood/Mamre Road Precinct)
Project Overview
The AirTrunk SYD3 Hyperscale Campus in Western Sydney is a colossal development and a critical piece of Australia's digital infrastructure, solidifying Sydney's status as a Tier 1 data center market. With a master-planned capacity exceeding 400 MW, it is currently positioned as the largest single-campus data center in the Asia-Pacific region outside of mainland China. This immense scale is specifically tailored to meet the relentless demand from global hyperscale cloud providers—such as Amazon Web Services (AWS), Google Cloud, and Microsoft Azure—who require massive, flexible capacity to support their accelerating cloud and AI workloads in the region.
The facility's design is focused on efficiency and speed of deployment. Leveraging modular construction techniques, AirTrunk has been able to bring initial capacity online rapidly, a key requirement for its major tenants. Crucially, the campus is designed to achieve an industry-leading low Power Usage Effectiveness (PUE) of 1.15, employing advanced cooling technologies optimised for the local environment. This focus on efficiency is paired with a strong commitment to sustainability, with AirTrunk actively securing Power Purchase Agreements (PPAs) with renewable energy generators (solar and wind) to ensure the power consumption of its facilities is offset by green energy sources.
The strategic location in Western Sydney, near the existing SYD1 campus, allows customers to scale with ease and take advantage of existing network synergies. Backed by significant institutional investment (most recently acquired by Blackstone in a major transaction), the AU$1 billion+ project reinforces Australia's position as a stable, high-trust digital gateway for the entire APAC region, delivering the necessary high-capacity, low-latency, and sustainable infrastructure that the world's largest technology companies demand.
