Australia’s Data Centre Construction Boom Faces Infrastructure Limits

Australia is embarking on a substantial data centre construction boom, with activity projected to rise significantly through the decade, driven by growing demand for cloud computing and artificial intelligence. However, logistical constraints such as electricity supply, grid capacity, labour availability and resource competition will determine which projects are realised, affecting infrastructure demand and economic outcomes.

Data Centre Construction Set to Surge by FY29

Oxford Economics Australia’s analysis forecasts that data centre construction work will increase from approximately A$5.3 billion in FY26 to peak near A$14 billion in constant 2023/24 prices by FY29, surpassing other non-residential building sectors to become the seventh-largest construction sector overall. This marks a rapid ascendency from 28th place in FY23 and highlights the sector’s expanding role within construction markets.

Power Constraints to Influence Project Locations

Data centres demand considerable electricity; national consumption is forecast to grow from around 5 TWh in FY26 to nearly 34 TWh by FY36, increasing their share of the National Electricity Market from 2.8% to over 13%. Oxford Economics Australia and AEMO identify power availability as a crucial factor that will influence the geographic distribution and pace of project development.

Not all announced projects will necessarily proceed; delays, cancellations or scaling-back can occur due to financing conditions, technology changes, or returns from artificial intelligence investments. Consequently, announced capacity figures should not be interpreted as guaranteed construction or resource demands.

Broader Infrastructure and Resource Challenges

Beyond power, data centre clusters will compete for water, land, materials and specialised labour, potentially increasing costs and causing delivery delays. The demand on infrastructure raises questions about funding responsibilities and economic justification from governments and local communities. The reported pipeline size does not guarantee proportional development in every location due to these various constraints.

Implications for Industry and Economic Value

While headline capital expenditure on data centres may reach more than A$60 billion annually by the decade’s end, much high-value IT equipment is imported. This means domestic construction activity and economic value will be less than total investment figures suggest. The current wave is construction-heavy due to new facilities, but future investments will increasingly focus on equipment replacement rather than new builds.

Operational data centres require ongoing maintenance, facility management and equipment upgrades, which will sustain local economic activity beyond construction phases. Understanding which projects are achievable and the timing of their delivery is critical for investors, utilities, governments and industry participants.

Oxford Economics Australia emphasises the need to move beyond headline announcements, integrating project intelligence with market and energy models to evaluate realistic construction timelines, infrastructure demands and economic benefits in Australia’s evolving data centre sector.
