South Australia's proposed $10B AI data centre sparks water, energy, and job concerns
Consensus Summary
South Australia is at the center of a debate over a proposed $10 billion AI data centre by IREN in Bundey, near the River Murray, which would be one of the largest in the Asia Pacific region and operational by 2028. The project has sparked concerns among local farmers, conservationists, and residents about water depletion, particularly in a semi-arid region already facing water shortages. While supporters, including the South Australian government and regional councils, highlight potential job creation and economic benefits, critics argue that the project could strain water resources and energy grids, with projections suggesting data centres could consume up to 10% of Australia’s east coast electricity by the mid-2030s. The state government is drafting legislation to regulate AI data centres, aiming to balance economic growth with sustainable resource management, though questions remain about whether current plans will adequately address environmental and community concerns. Nationally, Australia is experiencing a boom in data centre development, with over 160 operating and 90 proposed, raising broader questions about energy demand, water use, and long-term economic benefits.

Key details reported by multiple sources:
- A proposed 800-megawatt data centre by IREN in Bundey, South Australia, would be one of the largest in the Asia Pacific region, with an estimated $10 billion cost and planned operation by 2028.
- The Bundey data centre would use a closed-loop cooling system, with IREN stating that after the initial fill, less than 1% of its total on-site tank capacity would be depleted annually.
- The proposed Bundey data centre is located near the Bundey electrical substation, which integrates large-scale renewable energy into the National Energy Market.
- South Australia’s government is drafting legislation to regulate AI data centres, aiming to streamline development processes and ensure energy and water use are managed appropriately.
- The South Australian government is promoting AI data centres as a source of regional job creation, particularly in areas like the Mid North and Whyalla, where renewable energy and water infrastructure already exist.
- Concerns about water use from the River Murray for data centres have been raised by local farmers, conservation groups, and residents, given South Australia’s semi-arid climate and reliance on the Murray-Darling Basin.
- The proposed Bundey data centre would create 200 ongoing skilled jobs in the region, according to IREN.
- The South Australian government is considering using the $5 billion Northern Water pipeline project, which supplies water to BHP’s mining operations, to potentially support new data centres.
- Data centres in Australia currently account for 2.8% of electricity consumption on the east coast, with projections that this could rise to 7% by 2030 and above 10% by the mid-2030s.
- The Mamre Road data centre in Sydney’s outer western suburbs, if approved, would be one of the biggest in the world, consuming more power than the Tomago aluminium smelter.
Points of Difference
Details reported by only one source:
- Clayton Heinrich, a farmer near Bundey, expressed concerns about the impact of the data centre on his property and local tourism, stating that the project 'came out of the blue'.
- Teresa ter Bogt, secretary of the Bookmark Creek Action Group, warned that any large-scale water use from the River Murray would harm the ecosystem and local communities.
- Henry Schutz, a farmer near Bundey, raised national security concerns, stating that the data centre could make the region a target due to its water, power, and AI infrastructure.
- Goyder Regional Council Mayor Bill Gebhardt welcomed the project, calling it a positive development for job creation and regional growth.
- Tori Widmer, a cafe manager in Morgan, expressed concerns about housing shortages and the long-term impacts of the data centre on the local community.
- The South Australian government stated it is working with IREN to develop a framework for managing large-scale data centre proposals, emphasizing innovation and job creation.
- IREN’s CEO Daniel Roberts mentioned that the Bundey data centre would use a 'very, very small amount of up-front water,' equivalent to a few Olympic-sized swimming pools.
- The Greens established a federal parliamentary inquiry into AI data centres, with Senator Sarah Hanson-Young calling for legally binding rules on water usage.
- Alex Hooper, head of climate and energy economics at Oxford Economics Australia, stated that data centres could account for 7% of east coast electricity consumption by 2030 and above 10% by the mid-2030s, with significant upside risk.
- The Climate Council estimates that wholesale electricity prices on the east coast could be 20% higher by 2035 if extra data centre demand is not offset by additional renewable energy sources.
- Pat Bustamante, a senior economist at Westpac, argued that the data centre boom is good for the economy, laying the foundation for the next wave of productivity growth.
- Beth Webster, an economics professor at Melbourne University, suggested that Australia can avoid the pitfalls seen overseas by implementing strict rules around data centre development.
- The Mamre Road data centre in Sydney would include six four-storey buildings, 936 cooling units, and 852 diesel backup power generators, making it the country’s single biggest energy user if approved.
Contradictions
Conflicting information between sources:
- The ABC reports that IREN’s closed-loop cooling system would use 'a few Olympic-sized swimming pools' of water upfront, while the Guardian does not provide a specific number but highlights broader concerns about water use in data centres without quantifying IREN’s claims.
- The ABC states that the Bundey data centre would create 200 ongoing skilled jobs, while the Guardian does not mention specific job numbers for the Bundey project but notes that data centres typically create thousands of jobs during construction but only hundreds once operational.
- The South Australian government, as reported by the ABC, claims that water use in data centres is 'nowhere near in the volumes' asserted by critics, while the Guardian emphasizes that data centres still consume significant water for cooling, particularly in Australia’s dry climate.
- The ABC reports that the Bundey data centre is proposed to be adjacent to the Bundey substation, while the Guardian does not specify the exact location of the Bundey data centre but focuses on broader concerns about data centre expansion in Australia.
