Data centres are booming in Australia - but at what cost?

What the report says

Data centres are expanding rapidly across Australia, with BBC World News reporting that the country now has 162 facilities and plans for about 90 more, alongside an estimated A$155bn in investment. The story, published in Sydney, says the boom has been encouraged by interest from global tech firms, Australia’s land supply, energy mix and relative political stability. Supporters argue the sector could create jobs, attract capital and help support domestic AI development.

The article also highlights growing concern from residents and experts about the impact on power, water and local communities. People living near existing or planned sites in Sydney’s Lane Cove and western suburbs described noise and disruption, while environmental groups warned that the sector could strain the electricity grid and increase pressure on water supplies. BBC World News notes that Australia’s energy market operator expects data centre electricity demand to triple by 2030, and that some assessments warn of higher power prices in New South Wales without major new renewable capacity and storage.

Water use is another major issue because data centres need cooling to protect servers. The report says some facilities can use very large volumes of water, raising concerns in a drought-prone country already planning for higher household demand. The Australian government has said large-scale new data centres will face obligations on power and water use from 2027, but critics want a pause on new development. The debate reflects a wider question for Australia: whether the economic benefits of becoming a regional AI and cloud hub outweigh the environmental costs.
