A $9-billion hyperscale data centre campus proposed for Kemps Creek could become one of the largest digital infrastructure developments in Australia, further cementing Western Sydney’s role as a growing technology and logistics hub. The State Significant Development application proposes a 1.2-gigawatt data centre campus at 706–752 Mamre Road within the Western Sydney Employment Area, with the project currently on public exhibition and being assessed by the NSW Department of Planning, Housing and Infrastructure.

If approved, the development would deliver a large-scale digital infrastructure campus across a 52-hectare site, comprising 26 data hall shells across six purpose-built buildings. The structures would reach heights of up to 40 metres and would be constructed in stages over approximately a decade, depending on market demand and tenant requirements. The project significantly exceeds the 15-megawatt threshold that triggers State Significant Development assessment, reflecting the scale of infrastructure now required to support cloud computing, enterprise storage and data processing for Australia’s digital economy.

Campus scale and infrastructure

The proposed campus would contain approximately 172,640 square metres of technical data hall space alongside 54,854 square metres of ancillary office and corridor floor area, supporting a large hyperscale facility designed to operate continuously. Across the site, six development parcels would be established, each with its own electrical substation and associated infrastructure required to support high-density computing operations.

The facility would include substantial mechanical and electrical plant necessary for hyperscale operations, including 728 cooling units, 846 backup generators and large-scale battery storage totalling more than 2,652 tonnes of lithium-ion systems. Diesel fuel storage on the site would total approximately 18,056 kilolitres to support backup generation systems during grid outages or maintenance events. The campus would also include 619 at-grade parking spaces, water tanks for fire protection systems and extensive internal road infrastructure connecting the individual development parcels.

Power for the campus would be supplied through three lead-in connections from TransGrid’s Sydney West substation, allowing the project to meet its projected 1.2-gigawatt electricity demand. The development would operate 24 hours a day once completed, reflecting the continuous nature of global cloud and data services infrastructure.

Strategic location in Western Sydney

The site is located within the Mamre Road Precinct, a key component of the Western Sydney Employment Area that was rezoned by the NSW Government in 2020 to facilitate approximately 850 hectares of new industrial development. The precinct has been identified as a major employment and logistics corridor supporting the Western Sydney Aerotropolis, with new industrial estates, logistics facilities and emerging data centre developments already underway across the area.

Positioned approximately 8.5 kilometres northeast of Western Sydney Airport, the site benefits from regional transport connectivity through Mamre Road and direct access to the M4 and M7 motorways. The availability of large industrial land parcels, proximity to electricity transmission infrastructure and strategic planning support for employment uses have contributed to the rapid emergence of the corridor as a preferred location for large-scale logistics and technology infrastructure projects.

The proposal aligns with broader state and national digital infrastructure strategies, which seek to expand sovereign data storage capacity within Australia and support the growing demand for cloud computing, artificial intelligence and enterprise data services. The Environmental Impact Statement identifies Western Sydney as a strategic location capable of supporting hyperscale facilities due to its land supply, infrastructure capacity and proximity to major population centres.

Economic impact

According to the Environmental Impact Statement prepared in support of the application, the proposed campus represents approximately $9 billion in construction investment. The scale of the development is expected to generate substantial economic activity across Greater Sydney during both the construction and operational phases of the project.

During construction, the project is estimated to support more than 10,500 direct jobs associated with site works, building construction and infrastructure delivery. Once operational, the facility is expected to support approximately 800 ongoing roles associated with data centre operations, technical maintenance and associated services.

The economic assessment prepared for the project estimates that construction of the campus could generate approximately $13.7 billion in economic output across the region, alongside billions of dollars in income and economic activity flowing through supply chains. These projections reflect the scale of construction activity required to deliver the large mechanical and electrical infrastructure systems necessary for hyperscale data centre operations.

Planning framework and site history

The land is zoned IN1 General Industrial under the State Environmental Planning Policy (Industry and Employment) 2021, making data centre development permissible with consent. A portion of the site along Mamre Road is also reserved under the SP2 Infrastructure zoning to accommodate future road upgrades planned for the corridor.

The Secretary’s Environmental Assessment Requirements for the project were issued on 30 September 2025, requiring the preparation of a comprehensive Environmental Impact Statement addressing planning, environmental and technical matters associated with the proposal. The site itself is currently vacant and consists primarily of cleared grassland with six dams and small areas of remnant vegetation.

Most of the land has been identified as urban-capable certified land under the Cumberland Plain Conservation Plan, meaning it has been identified as suitable for development within the broader strategic planning framework for Western Sydney. The Environmental Impact Statement also identifies surrounding development as predominantly industrial, reflecting the planned evolution of the Mamre Road corridor as a major employment precinct.

Exhibition and next steps

The State Significant Development application is currently on public exhibition, allowing members of the community, government agencies and other stakeholders to review the proposal and make submissions. Following the exhibition period, the Department of Planning, Housing and Infrastructure will consider submissions received and undertake a detailed assessment of the project.

The Department will then prepare an assessment report and recommendation before the application proceeds to determination under the State Significant Development framework.
