Key Takeaways
- Australia’s datacentre sector is expanding rapidly to support AI and digital services, with projects like NextDC’s M3 in West Footscray, Goodman Property’s Project Mars in Lane Cove, and GreenSquareDC’s Hazelmere facility in Perth.
- Residents near these sites raise concerns about noise, air quality, visual impact, power consumption, and potential harm to local ecosystems and cultural heritage.
- Community groups argue that datacentres, despite being classified as “critical infrastructure,” are being sited too close to homes, schools, parks, and wetlands, and that current zoning decisions did not anticipate the massive scale of today’s hyperscale centres.
- Local councils have expressed opposition or called for better planning, but final approval rests with state governments, which are fast‑tracking assessments while encouraging public consultation.
- Industry representatives acknowledge the tension between development and livability, stress compliance with environmental standards, and contend that domestic AI infrastructure is essential to avoid reliance on foreign technology.
Overview of Australia’s datacentre boom and community pushback
Australia is experiencing a surge in datacentre construction driven by the promise of an AI‑powered economy and the need for sovereign digital infrastructure. Projects are being marketed as “hyperscale AI factories” that will deliver speed, scale, security, and sustainability. Yet, as these facilities grow—often doubling in size and power draw—they are increasingly abutting residential neighborhoods, parks, and waterways. Residents who live closest to the sites argue that the industrial scale of the developments clashes with the character of their communities, prompting a growing opposition movement that calls for better planning and more distant siting.
West Footscray’s M3 datacentre and resident Sean Brown’s concerns
In Melbourne’s inner‑west, Sean Brown walks his 19‑month‑old son past the ever‑expanding M3 facility operated by NextDC, which bills itself as “Australia’s largest hyperscale AI factory.” Brown describes constant construction noise, a looming visual presence, and a persistent hum from diesel generators that now number 40 and are slated to rise to 100. He worries that his child’s neurological, pulmonary, and physical development is occurring in the shadow of a plant whose cumulative environmental impact has never been formally assessed. For Brown, the datacentre represents an industrial intrusion with no clear community upside, and he believes the expansion is proceeding without adequate consideration of local effects.
Scale and future growth of the M3 facility
The M3 centre has already undergone several expansions and, if fast‑tracked planning approval is granted by the Victorian government, will double again by the end of 2027. At that point it will cover 10 hectares, draw approximately 225 MW of power, and operate continuously. The projected increase in diesel generators underscores the facility’s reliance on fossil‑fuel backup power, raising additional concerns about air emissions and noise pollution in a suburb already traversed by major roads and rail lines.
Lane Cove’s Project Mars and the visual‑impact debate
Moving north to Sydney, a proposal for a 90 MW datacentre dubbed Project Mars is under review by the NSW government. Situated near the Lane Cove River, the development would occupy roughly 22,000 m² across three storeys and would sit adjacent to Blackman Park—a former tip turned community sporting hub used by about half the suburb each weekend. Local resident Daniel Bolger warns that placing such a large industrial structure next to the park’s “lungs” threatens both recreational amenity and ecological balance, while also heightening concerns about proximity to schools and the visual dominance of the centre over bushland and residential zones.
Community sidelining and procedural concerns in Lane Cove
Bolger contends that the Lane Cove council has been effectively sidelined in the planning process, despite the project’s potential to exceed existing height limits and dominate the skyline. He highlights a “cluster issue,” whereby multiple datacentres already occupy 40 % of the local industrial zone, and adding another large facility intensifies cumulative impacts on power demand, traffic, and ambient noise. The NSW planning minister, Paul Scully, has said the public will be consulted and a merit‑based assessment—including an evaluation of energy needs—will precede any decision, but residents remain skeptical that their voices will meaningfully alter the outcome.
Hazelmere’s proposed datacentre and Indigenous concerns
In Western Australia, a 15,000 m², three‑storey datacentre with a capacity of up to 120 MW is proposed for Hazelmere, 15 km east of Perth. Local resident Kate Herren likens the scale to “bigger than a Bunnings warehouse” and argues the site is wholly unsuitable for a development of that magnitude. Walter McGuire, chair of the Bibbul Ngarma Aboriginal Association, stresses that the Noongar people hold cultural responsibilities for the Mandoon Bilya (Helena River) and its surrounding wetlands. He warns that the datacentre could jeopardize water quality, riparian habitats, and culturally significant landscapes, insisting that “giant datacentres belong in industrial areas, not on the banks of our rivers and wetlands.”
Environmental and cultural stakes in Hazelmere
The proposal is currently before the City of Swan council, which has not yet issued a public statement. GreenSquareDC, the developer behind the project, maintains that the site lies within an established industrial zone with robust transport and power links, and says it is taking community concerns—including proximity to a local school—seriously. Nevertheless, the Aboriginal association’s apprehensions underscore a broader tension: the push for digital infrastructure must be weighed against the protection of natural ecosystems and Indigenous heritage, especially when projects encroach on sensitive river corridors.
Industry perspective on datacentre siting and benefits
Belinda Dennett, chief executive of Data Centres Australia, acknowledges that constructing large datacentres can be confronting, particularly where industrial land abuts residential areas. She insists developers adhere to strict environmental and building standards and aim to minimise disruption. Dennett frames the sector as a significant economic opportunity, predicting new businesses, jobs, and flow‑on benefits for neighboring communities. In a NSW parliamentary inquiry, she warned that if Australia fails to build its own AI infrastructure, the nation risked becoming merely an importer of foreign technology lacking Australian cultural, legal, and value frameworks; conversely, domestic development would grant Australia greater control over how AI evolves locally.
Government processes, council opposition, and the path forward
Across the three case studies, local councils have voiced opposition or called for more careful planning, yet ultimate approval rests with state governments that are fast‑tracking assessments while encouraging public consultation. The Victorian government is reviewing the M3 expansion, the NSW administration is evaluating Project Mars, and Western Australian authorities are weighing the Hazelmere proposal. While officials stress merit‑based reviews and community input, residents remain wary that procedural safeguards may not adequately address the cumulative noise, emissions, visual intrusion, and ecological risks associated with hyperscale datacentres. The ongoing debate highlights the need for a national framework that balances the strategic imperative of AI‑ready infrastructure with the livability, environmental stewardship, and cultural respect owed to nearby communities.
