Australia data center growth tops $155 billion as tech giants pile in

Australia is edging toward a data center building boom that could reshape entire regions of the economy, as some of the world’s biggest technology companies quietly ramp up their appetite for local infrastructure. Speaking at the AFR Commercial Property Summit, Aware Super CEO Deanne Stewart said the country could unlock a wave of fresh capital if it manages to clear a familiar set of roadblocks: grid connections, zoning approvals, construction costs, and the simple problem of finding enough suitable land. The comments capture the tension defining Australia data center growth right now — enormous demand running up against infrastructure that wasn’t built for it.

Key takeaways

• Investment in Australia’s data centers could exceed $155 billion, delivering a $75 billion GDP boost and supporting up to 400,000 jobs, according to Westpac IQ.
• Google, Apple, Meta, Amazon, and Microsoft have shown a sharply higher appetite for Australian data center capacity than expected, according to AirTrunk Operating Pty Ltd.
• AI-driven data centers could consume 13% of Australia’s total power by 2035-36, up from 3% today, straining a grid regulators say can’t expand fast enough.
• Community pushback has already surfaced in New South Wales and Tasmania, where a petition topping 10,000 signatures triggered a parliamentary inquiry.
• Land shortages near major cities are pushing developers toward the Northern Territory and South Australia, where power constraints are less severe.

Surging Investment in Australia’s Data Center Market

Australia could be sitting on the edge of a multibillion-dollar expansion in data center capacity, driven almost entirely by demand from outside its borders. The scale of that demand is what’s turning heads: global capital allocated to data center companies already totals US$750 billion, and by some estimates could top US$1 trillion within a year, Stewart noted. For a country of Australia’s size, capturing even a modest slice of that flow would be transformative.

Major US Tech Companies Leading Demand

According to AirTrunk Operating Pty Ltd, the country’s dominant hyperscale operator, Google, Apple, Meta, Amazon, and Microsoft have all shown a significantly greater appetite for Australian capacity over the past few months than the industry originally expected. According to Robin Khuda, the CEO of AirTrunk, the present surge in AI infrastructure development represents “the biggest gold rush in human history.” The company itself carries a valuation of approximately A$24 billion following a Blackstone-led consortium acquisition in 2024, now operates more than 1.2 GW of capacity across five Australian campuses.

The pipeline keeps growing. AirTrunk’s MEL2 campus in Melbourne, announced in December 2025, is set to deliver over 354 MW of capacity at a cost exceeding A$5 billion. In Sydney, the company’s SYD3 project is targeting more than 400 MW, with A$4.3 billion in loan talks reportedly underway to finance construction. Microsoft, Amazon, Google, Apple, and Oracle all sit among AirTrunk’s major US clients, each competing for capacity across the Asia-Pacific region.

Projected Economic Impact and Job Creation

Digital analysis platform Westpac IQ had earlier estimated that investment in Australia’s data centers could easily surpass $155 billion. That figure, the firm said, could translate into a net GDP boost of roughly $75 billion and support as many as 400,000 jobs once economic spillovers into construction, energy, and telecommunications are factored in. Stewart framed the moment as a rare opportunity, noting that data center investment globally is generating returns of more than 20% per annum. “For Australia, that’s a great opportunity to do something significant with the investment coming here,” she said. Sabooh Whitelaw, associate vice president for energy and utilities, added that growing US demand could translate into concrete investment commitments over the coming years.

Infrastructure and Operational Challenges to Growth

The obstacles standing in the way of Australia data center growth are just as significant as the opportunity itself. Power availability, land scarcity, and slow approval timelines all threaten to slow a buildout that tech companies want moving quickly.

Grid Connection Constraints and Energy Demand

Power is the biggest pressure point. AI data centers are on track to consume 13% of Australia’s total electricity by 2035-36, a sharp jump from just 3% today. The Australian Energy Market Operator has cautioned that the nation’s capacity to construct new power infrastructure will lag behind the electricity demands of data centers transmission and generation capacity, a mismatch that could push costs onto everyday consumers. Compounding the problem, Australia’s planning and permitting processes lag comparable timelines in Asia by roughly two years, according to industry assessments cited by AirTrunk — a gap that matters enormously when competitors in Singapore or Japan are racing to build in the same window.

Land Availability and Construction Costs

Equinix senior director for real estate in APAC, Tim Robinson, pointed to land scarcity as an increasingly urgent constraint. “The cost of land is now a huge consideration for us, and we’ll see centers gravitate outwards over time, away from the city fringe,” he said. CommBank View economist Lucinda Jerogin echoed that shift, arguing that the availability of power, water, grid connections, and suitable sites will ultimately decide which projects move forward and where new clusters emerge. “We’re starting to see more projects proposed… in the Northern Territory, and in places like South Australia, where some of those electricity and grid constraints are less severe,” she said. Some developers have already moved toward renewable-rich sites: a 25 MW Mulwala Solar Farm in New South Wales, backed jointly by Google and AirTrunk under a 2023 power purchase agreement, is nearing grid connection and illustrates how clean energy access is shaping where facilities get built.

Community Opposition and Regional Shifts

Local resistance remains limited but is not absent. In New South Wales, activists are lobbying for an urgent freeze on further data center expansion. In Tasmania, a petition gathering over 10,000 signatures forced a parliamentary inquiry into a proposed moratorium. These pockets of opposition, combined with tighter land and grid conditions near major cities, are part of why development is increasingly gravitating toward the Northern Territory and South Australia.

Economic and Sectoral Implications of Data Center Expansion

Beyond the data centers themselves, the ripple effects could touch construction, energy, engineering, and telecommunications firms across the country — but the same buildout that creates jobs could also strain the resources other sectors depend on.

Broader Industry Opportunities and Risks

Artificial intelligence is the single biggest force behind rising data center demand. AI workloads require far more computing power than typical digital services, driving the need for larger facilities equipped with high-performance chips, advanced cooling, and dependable electricity supplies. That demand curve is why Stewart insists policy consistency matters more than any single incentive. “Australia has many advantages… while power and grid connections are constraints on growth, they’re not putting people off. What is important is consistency, consistency, and consistency in terms of government policy,” she said.

Resource Crowding and Economic Side Effects

Not everyone views the boom without concern. James McIntyre, an Australian economist with Bloomberg Economics, warned in a research note that data center construction will worsen existing supply constraints by pulling trades and construction capacity away from housing and renewable energy projects — two sectors already under strain. Ivan Colhoun, chief economist at CreditorWatch Pty Ltd, added that the surge will likely inflate material prices, labor demand, and wages, potentially muting the usual signals — like softer home approvals or cooling house prices — that guide monetary policy decisions.

That’s the real tension behind Australia data center growth: the same investment wave promising tens of billions in GDP gains and hundreds of thousands of jobs could also crowd out the tradespeople and materials needed to build homes and renewable infrastructure elsewhere. Whether policymakers can expand grid capacity and approval speed without squeezing other sectors will likely determine how much of that $155 billion opportunity Australia actually captures.
