Australia is currently undergoing a rapid expansion of data centre infrastructure, with 162 facilities already in operation and plans for 90 more. The country has attracted over A$155bn in investment, driven by its land availability, political stability, and renewable energy potential. Proponents, including industry leaders and government officials, argue that this infrastructure is vital for the digital economy and could prevent an economic recession.

Belinda Dennett, CEO of Data Centres Australia, emphasized that domestic infrastructure is necessary to ensure the country remains a participant in the global value chain rather than merely a consumer of foreign technology. NSW Treasurer Daniel Mookhey added that private sector investment in these facilities is helping to accelerate the transition to renewable energy by offsetting costs that would otherwise fall on households.

However, the boom has sparked significant backlash from local communities and environmental advocates. Residents in areas like Sydney’s Lane Cove have reported persistent noise pollution from nearby facilities, while others face displacement as industrial parks are repurposed for tech infrastructure. Critics also point out that while data centres create construction jobs, they offer relatively few permanent positions once operational.

Environmental concerns remain a primary point of contention. The Climate Council has warned that data centres could drive up electricity prices in New South Wales by 26% by 2035 if renewable capacity does not keep pace. Furthermore, there are fears that the high energy demands of these facilities may necessitate the construction of new coal or gas-fired power plants. Water usage is another critical issue; Sydney Water estimates that data centres could consume up to 25% of the city’s drinking water by 2035 to manage server cooling, potentially straining resources during drought periods.

In response to growing pressure, Prime Minister Anthony Albanese announced plans for legislation to be introduced in 2027 that would require new large-scale data centres to underwrite their power supplies and limit water usage. Critics, including local officials like Lane Cove Deputy Mayor Rochelle Flood, argue that these measures do not address projects already under construction and question whether the environmental cost is justified by the current applications of generative AI.
