Economic analysis finds Australia's data center buildout poses inflation and macroeconomic risks amid power constraints.
Australia is in the midst of a data centre construction boom. Driven by artificial intelligence and growing demand for digital services, global technology companies are expected to invest up to A$150 billion in Australian data centres by 2030.
Yet a critical question remains: will Australia gain lasting productivity and economic growth, or merely benefit from a temporary construction surge?
Data centres—facilities packed with computers that store, process and move digital information—can create jobs, strengthen digital infrastructure and support AI development. But they also exert pressure on housing, electricity networks and skilled labour. While such facilities have existed for decades, they have recently become central to major policy debates.
**Why Australia is attractive**
Australia offers global technology firms several advantages: political stability, strong institutions and proximity to the fast-growing Asia-Pacific region. Construction projects create immediate work for engineers, electricians and builders, and increase demand for materials, electricity infrastructure and specialised equipment.
However, the boost to economic growth may be smaller than headline investment figures suggest. A large share of spending goes toward imported goods—servers, processors, chips and networking equipment—meaning much of the money leaves Australia rather than circulating through the local economy.
**Competition for workers and resources**
Every major investment boom brings trade-offs. One of the most significant is competition for construction labour. Data centres require many of the same workers needed to build houses, roads and renewable energy infrastructure. Australia already faces shortages of up to 72,000 electricians, engineers and skilled trades, with media reports indicating electricians with just two years' experience commanding salaries of $200,000 annually to work on data centre projects.
If data centres absorb more of these workers, labour costs could rise across the economy. Housing projects may become more expensive, infrastructure projects could face delays and renewable energy developments may struggle to secure workers—a particular concern given that housing affordability remains one of Australia's biggest economic challenges.
Demand for electricity and water will also increase. If supply doesn't keep pace, prices could rise for households and businesses. Land allocated for data centres might otherwise have been used for housing, logistics facilities or other productive purposes.
**Inflation pressures**
The Reserve Bank of Australia has raised concerns about capacity pressures in the economy and identified several ways data centres could contribute to inflation. First, stronger competition for skilled workers may push wages higher in construction and related industries. Second, increased demand for construction materials could drive up project costs across the economy. Third, a large inflow of investment can add to demand at a time when policymakers are attempting to keep inflation under control, potentially making it harder for the Reserve Bank to bring down inflation—currently well above the 2–3% target band.
**The copper wildcard**
Data centres use large quantities of copper for cables, power systems and cooling equipment. As they are built globally, copper demand is expected to surge significantly. S&P Global forecasts total global copper demand will increase by around 50%, climbing from 28 million metric tonnes in 2025 to 42 million metric tonnes by 2040.
Higher copper prices benefit Australia's miners. BHP, the world's largest copper producer, recently reported that copper contributed more than half of its earnings for the first time, surpassing iron ore, as copper prices surged nearly 50% over the year.
Yet higher copper costs impose burdens on domestic construction projects, electricity networks and renewable energy developments—illustrating how the same economic trend can create gains for some industries while imposing costs on others.
**Capturing value**
The most important question is who captures the value data centres create. Owning the buildings does not necessarily mean owning the technology. Many data centres are operated by multinational companies that also control the software, intellectual property and AI systems within them. If Australia hosts the infrastructure but develops few local AI-related capabilities, much of the long-term value may flow overseas.
As Andrew Charlton, assistant minister for the digital economy, recently noted: "Simply building data centres in Australia does not necessarily mean that Australia captures the economics of AI. We can supply the land. We can supply the electricity. We can host the machines. And still find that much of the value […] flows offshore."
The biggest gains are likely to come from building domestic expertise in AI, software development and digital services.
**Policy priorities**
The key policy challenge is maximising benefits while minimising costs. This requires expanding the supply of skilled workers, electricity infrastructure and industrial land so that data centre construction does not crowd out housing, renewable energy and other important investments.
Training more electricians, engineers and technical specialists will be part of the solution, though training takes time. In the short term, carefully targeted migration policies may help ease labour shortages in critical occupations.
Australia's data centre boom brings investment, jobs and the promise of a sophisticated digital economy. But it also creates new pressures on housing, energy and skilled workers. The real challenge for policymakers is ensuring Australia captures enough of the value these investments create. If governments strike the right balance, the current boom could boost productivity and strengthen Australia's position in the global digital economy. If they do not, Australia may find that the benefits of the construction boom are fewer than the investment figures suggest.
