Rapid AI datacenter demand in Australia risks driving inflation and crowding out housing land.

Transport for NSW and the Reserve Bank have warned that datacentres could consume scarce land designated for logistics firms and housing developments, potentially pushing up prices and overheating the economy, as calls grow for a national pause on the rapidly expanding sector.

The transport department agency told a state parliament inquiry on datacentres that there is already significant pressure on the availability of industrial land and infrastructure. In its submission, Transport for NSW noted that freight and logistics companies depend on industrial land near markets and transport hubs. "The shortage of land is causing major freight and logistics operators to leave Sydney. They are relocating their main centres to Brisbane or Melbourne where suitable land is available and less expensive," it stated.

While acknowledging that industrial land vacancy rates have improved nationally and in Sydney in recent years, Transport for NSW cautioned that rates remain "well below international rates and below the ideal market level." The department warned that fragmentation of freight activities due to competing land uses could result in increased costs for business and higher prices for consumers, emphasizing that government must implement coordinated policy to manage land use strategically.

Data Centres Australia, the peak body for the datacentres sector, cited CBRE research showing the vacancy rate is now close to 4%. Chief executive Belinda Dennett said supply is responding with "strong new development and continued logistics investment in western Sydney," advocating for releasing and servicing more land while ensuring "freight keeps the transport-connected sites it depends on while datacentres deliver the investment, jobs and infrastructure they bring."

The Australasian Supply Chain and Logistics Association backed Transport for NSW's position. Its chief executive, Steven Ballerini, stated: "We're not opposed to datacentres as they're critical infrastructure for the digital economy. But they are now competing directly with freight and logistics for the same well-located industrial land, and that's a competition with real consequences. Unlike a datacentre, a distribution centre has to sit close to the population it serves; you can't simply move it to the urban fringe without adding cost, distance and emissions to the supply chain."

The Reserve Bank board has cautioned that rising investment in datacentres could contribute to inflation and has already exerted upward pressure on interest rates worldwide. Datacentre spending now comprises a growing share of Australia's machinery and equipment investment, which was the single largest contributor to economic growth in early 2026. Commercial and industrial building approval values reached a record high in May due to new datacentre projects, the Australian Bureau of Statistics reported.

The board discussed risks that the buildout could exacerbate skills shortages, with construction costs already elevated and workers scarce before datacentre projects began hiring. Pat Bustamante, a senior economist at Westpac, said the RBA would need to raise rates to curtail spending elsewhere if datacentre spending competed for land and resources while pushing up prices. "The RBA essentially will have to make room for this expansion because this expansion isn't really interest [rate] sensitive," he said. He warned that home building would face the most pressure if costs or rates rise further.

Community groups across NSW, Victoria and Western Australia have allied to call on state and federal governments to halt approval of new datacentre developments until stronger protections for communities, cultural heritage and the environment are in place. The Lane Cove Responsible Planning Group highlighted that five datacentres are planned for the northern Sydney suburb and would consume 40% of its industrial land. The alliance stated: "[Datacentres] take up space that could be used for other community infrastructure, green spaces and housing. And they contribute to greenhouse gas emissions and climate change. Our existing planning systems were never designed to assess or manage hyperscale AI infrastructure and the pressures they put on energy and water systems and the community."

Federal Labor backbencher Ed Husic raised similar concerns, telling Sky News: "There's been a bit of a frenzy going on with datacentre builds … Land gets snapped up that should have been set aside for houses, and we've already got 90,000 workers short in construction. So if we are having a situation where datacentres are now taking up land for homes, we've got to pump the brakes on this."

Assistant minister for the digital economy Andrew Charlton responded that the government's top priority is building new homes, stating: "States and councils need to prioritise housing in their local planning decisions. The collective task of policymakers is to ensure investment in datacentres work in the interests of Australians, not the other way around."

Dennett countered that while communities deserved a genuine say in what gets built around them, a moratorium was the wrong approach. "Datacentres in Australia are already assessed through rigorous, independent planning that requires environmental assessment, community consultation, cultural heritage protection and binding conditions of approval, and they can only be built on industrial and employment land," she said. "A blanket pause would freeze the whole industry to legislate safeguards that for the most part already exist, while sending the investment, the jobs and the local infrastructure these projects bring to other countries."
