Powering the Boom: How AI Is Driving Australia's Data Centre Race and What It Means for Engineering M&A

How AI is actually driving the build out

It’s worth being precise about what’s behind this, because it changes how owners should think about how long it runs. This isn’t simply Australia building more general digital infrastructure as the economy grows. It’s a race that exists specifically because of AI, and it’s already large enough to matter at the level of the entire national economy. The same ABC analysis pointed out that when the latest national accounts data was released, one thing stood out: had it not been for the capital pouring into AI infrastructure, the Australian economy would have slid into contraction. That’s a striking marker of how central AI-specific investment has become to overall growth, not a side effect of it.

The capital behind that investment is also telling. It isn’t coming from telcos or generic enterprise IT budgets, it’s coming directly from the companies building and running AI models themselves. Microsoft has pledged around $25 billion to build AI and cloud capacity across the country, AWS has committed roughly $20 billion, and OpenAI is developing a dedicated Sydney campus with local operator NEXTDC. Morgan Stanley has estimated that power demand from generative AI specifically is growing at around 70% a year through to 2027, a rate that only makes sense if you accept that this is an AI driven build out rather than a broader digital one.

That AI specific intensity is also reshaping which engineering services are seeing the strongest demand. Electrical infrastructure design, covering the substations, switchboards and distribution systems needed to feed AI scale power loads, accounted for close to 40% of the entire Australian data centre construction market in 2025, according to Mordor Intelligence. Mechanical and cooling design is close behind and growing even faster, with Schneider Electric reporting that 70% of its Australian projects last year involved liquid cooling design work specifically, a service line that barely existed at this scale before AI driven density pushed conventional air cooling past its limits.

The scale backs up the “mining boom” comparison. CommBank estimates Australia’s total data centre pipeline could reach around $150 billion by 2030, representing roughly six gigawatts of potential capacity, about four times the country’s entire operational capacity at the end of 2025. Deloitte’s own project tracker had counted 33 confirmed data centre projects worth a combined $104 billion as of August 2026. The Australian Bureau of Statistics reported that data centre construction and server spending made up 17% of all private investment in the March 2026 quarter alone, the highest share on record. Whichever number you anchor on, the conclusion lines up with the ABC’s framing: this has become one of the single largest forces in Australian business investment, not a niche technology story sitting off to the side of it.

What this is doing to buyer behaviour in engineering M&A

This is the one part of the story that’s really about dealmaking rather than demand, so it’s worth treating as its own, contained question. What are buyers actually doing differently because of it?

The clearest pattern is that global engineering consultancies are treating Australian data centre and mission critical capability as something worth acquiring rather than building organically. AtkinsRéalis completed two Australian acquisitions inside six months (ADG Capital in December 2025 and WGA in April 2026), while Tetra Tech picked up SAGE Group in mid-2025 and Providence Consulting in January 2026. WSP, Stantec, AECOM, Jacobs and Arcadis have all been active acquirers across Australia and New Zealand over the past few years. As one legal analysis from MinterEllison put it plainly, “data centres are now a premium M&A asset class in Australia,” driven by AI, cloud adoption and data sovereignty concerns. That mirrors what’s happening globally too. PitchBook recently found private equity activity in construction and engineering hit a record number of deals in the June quarter, concentrated specifically in the trades that build and equip these facilities.

What makes the Australian version of this distinctive, though, is the regulatory layer sitting underneath it. Deals involving data centre and digital infrastructure assets increasingly attract FIRB scrutiny and obligations under the Security of Critical Infrastructure Act, and the federal government’s own expectations for data centre and AI infrastructure developers, published in March 2026, put national security and resilience considerations squarely into the diligence process. For engineering firm owners with real exposure to this end of the market, that’s not a side issue. It’s now a live part of how a sale process gets structured and how long it takes to close.

What this means if you’re an engineering firm owner

If your firm has real, demonstrable capability in the disciplines this build out actually depends on (power and grid engineering, mission critical MEP, commissioning, or the specialised design work data centres require), you’re sitting in one of the most actively contested corners of the Australian AEC market right now, with global consultancies competing directly for that capability through acquisition. But the story above should also tell you what buyers will actually test for in diligence: genuine technical specialisation and a track record with credible clients, not just a data centre reference on the website, and increasingly, a clear eyed view of the regulatory and critical infrastructure obligations that now sit alongside any deal in this space.
