Australia’s data centre investment pipeline has grown beyond $155bn — about 5.6 per cent of a year’s GDP — as AI workloads drive a nationwide build-out, according to analysis from Westpac.
The bank estimates the investment could deliver a net GDP boost of around $75bn and temporarily support close to 400,000 jobs as projects roll out. Hyperscalers have led the charge, with Amazon Web Services and Microsoft among those committing billions to Australian campuses in recent years.
Government forecasts cited alongside the boom expect data centre capacity to more than double, from 1,350MW in 2024 to 3,100MW by 2030.
Why it matters
Compute is the new heavy industry. Where a generation ago Australia argued about smelters and mines, the debate now is about where gigawatts of AI capacity get built, who powers them and who benefits.
Energy is the binding constraint. Data centres are enormous, constant consumers of electricity, and a $155bn build-out lands squarely on top of an already stretched grid and the transition to renewables.
There is a sovereignty dividend too. Compute built on Australian soil keeps sensitive workloads onshore — but only if local companies and researchers can actually get access to it, rather than watching it fill with offshore demand.
