Data centers supercharge Australia's A$1.4T project pipeline - and stoke inflation risks

The scale and what is powering it

A fresh Deloitte Access Economics review of active and planned works puts Australia's project pipeline at A$1.4 trillion through September, or about $975 billion. Spending tied to projects that have started or been formally committed climbed to A$563 billion, led by transport as cities add roads, subways and related builds.

Data centers are the standout new driver. Close to 40 additional facilities totaling A$141 billion are now in the queue, roughly a third above last year's count. In the third quarter, data centers dominated the pipeline's new announcements, topped by Queensland's Western Downs Digital Park, where US AI firm Anthropic PBC finalized a lease in September.

"Data centers are the newest driver, but they're being added to a pipeline that is already historically large," said Sheraan Underwood, the report's author. "Transport and social infrastructure investment is still elevated, and it now overlaps with the net zero transition and the build-out of the digital economy."

Capacity crunch meets sticky inflation

Deloitte says the rapid buildout of data centers is tightening capacity, drawing electricians and other trades from competing work and pushing up costs. That sits alongside stronger than expected business investment that the Reserve Bank of Australia and the government have repeatedly highlighted, even as the war in the Middle East has lifted energy prices and squeezed households.

To counter price pressures, the RBA has raised interest rates five times this year. One marker of that investment strength: businesses spent almost A$180 billion in the first half of 2026, per seasonally adjusted Australian Bureau of Statistics data.

Power, pushback and potential delays

These facilities need reliable, around the clock power. At the same time, Australia is retiring older coal plants and leaning more on variable wind and solar. If spending on generation, storage and the grid fails to keep up, the rollout may be pushed back.

Locating data centers near major cities is also becoming less popular, with resistance building over their water and electricity demand. Last month, a developer behind one of Australia's largest planned data centers ran into power supply issues, highlighting that electricity access may turn into a bottleneck for artificial intelligence infrastructure.

Why it matters for your portfolio

Commonwealth Bank of Australia estimates the data center buildout could reach A$150 billion by 2030, pointing to steady demand for contractors, materials, and power equipment. Brisbane is already booming ahead of the 2032 Olympic Games, while Sydney and Melbourne are adding train lines and motorways to keep up with population growth.

The bottom line: overlapping waves of transport, social infrastructure and digital builds are propping up activity, tightening labor and energy markets, and sustaining price pressure. That mix shapes earnings trajectories for builders, suppliers, utilities and grid operators, and it sets the backdrop for the RBA's next moves on rates.
