Project Mars data centre: Goodman Group scraps A$1.2bn plan

Why did Goodman Group scrap the Project Mars data centre?

Goodman Group, Australia's largest property company, has officially withdrawn its application for the A$1.2bn 'Project Mars' facility following intense, concerted opposition from local residents and campaigners. The developer confirmed the decision in a formal letter to the New South Wales Department of Planning, outlining a complex mix of community push-back and a shifting regulatory landscape as the primary drivers for the withdrawal.

The proposed 90-megawatt facility was slated for the Lane Cove area, but the scale of the project and its specific location proved too contentious to proceed. In its communication to the planning authority, Goodman Group noted that since it initiated the formal planning process in March 2025, the company had undertaken extensive technical investigations, stakeholder engagement, and community consultation processes to gauge the viability of the site.

However, the company stated that during this period, the policy and regulatory environment for large-scale data centre development has evolved significantly. After carefully considering these evolving regulatory shifts alongside the direct views expressed by the local community, the firm concluded that it would not proceed with the development. This decision marks the end of a high-stakes attempt to integrate a massive industrial-scale data hub into a sensitive suburban environment.

The scale of community opposition

The level of public engagement regarding the Project Mars proposal was not merely significant; it was historic for the region. According to the local news website In the Cove, the consultation process for the project received a total of 374 submissions. Of these, only nine expressed support for the development, representing a near-unanimous rejection from those who engaged with the planning process.

This figure stands as the highest number of submissions ever recorded for a data centre application in the area, according to In the Cove. Such a high volume of feedback underscores the depth of local concern and the effectiveness of the opposition led by residents and groups such as the Lane Cove Responsible Planning Group. The sheer number of submissions served as a clear indicator to both the developer and the government that the proposal lacked the necessary social license to move forward in its current form.

What were the primary concerns of the Lane Cove residents?

Local residents were primarily driven by the extreme proximity of the proposed data centre to existing residential properties. The Project Mars facility was designed to be constructed approximately 20 metres from the nearest house in the Lane Cove suburb. This physical closeness—a mere 20-metre buffer—sparked a concerted movement to prevent an industrial-scale facility from encroaching directly onto suburban living spaces.

Beyond the immediate physical proximity and the potential impact on the character of the suburb, the dispute reflects much broader anxieties regarding the resource requirements and infrastructure demands of such massive installations. Data centres are characterized by their heavy reliance on local utility networks, and the Project Mars proposal highlighted several critical points of friction:

• Energy Supply: The 90-megawatt requirement of Project Mars highlights the massive electrical load these facilities place on the local and regional grid.
• Water Consumption: Large-scale data centres often require significant water volumes for cooling systems, raising fears among residents about the stability and availability of local water supplies.
• Community Disruption: Residents expressed concerns over the general industrialisation of the suburb, including the noise, visual impact, and the overall disruption caused by hosting such a large-scale facility in a residential zone.

The opposition was not just about the building itself, but about the precedent it would set for the intersection of high-tech industrial needs and residential community well-being.

How is the demand for data centres impacting Australia?

The cancellation of the Lane Cove project occurs against a backdrop of surging global demand for data centre infrastructure, a trend driven largely by the mainstreaming of generative artificial intelligence. As AI technologies become more integrated into global industry, the need for processing power has skyrocketed, making Australia an increasingly attractive destination for global investment.

The nation's appeal as a global hub for data centre construction is rooted in several strategic advantages that cater to the needs of global AI companies. Specifically, Australia offers:

• Abundant Clean Energy: As companies seek to meet sustainability goals, Australia's transition toward renewable energy makes it an attractive site for offsetting the massive carbon footprints associated with AI processing.
• Natural Gas Reserves: The presence of natural gas reserves provides a reliable and existing energy backbone to support the intense power requirements of large-scale facilities.
• Available Land: The availability of land allows for the massive physical footprints required by modern hyperscale data centres.

However, this influx of interest creates a complex policy paradox for the Australian government. While there is a strong desire to attract high-value AI investment and the associated economic benefits, the government must simultaneously manage the intense pressure these facilities place on local water and energy supplies. The Lane Cove case demonstrates that the drive for technological investment can run directly into the realities of community resistance and resource management.

What is the new regulatory approach in New South Wales?

The withdrawal of Project Mars follows a recent, significant shift in how the New South Wales government intends to manage the growth of this sector. Just last month, the state government announced the introduction of a dedicated fast-track programme designed to accelerate the development of data centre infrastructure across the state.

This new programme is intended to streamline the approval process, allowing qualified projects to be assessed within a strict 75-day window. This is a major departure from traditional planning timelines, aimed at keeping pace with the rapid global demand for AI capacity. To qualify for this expedited treatment, developers must meet rigorous requirements, including:

• Standard Compliance: Projects must meet specific, high-level technical and operational standards.
• Infrastructure Funding: Developers must provide the necessary funding to support the additional supply of water and energy that their facilities will demand from the state.

Despite this move toward administrative efficiency, the Lane Cove outcome suggests that a fast-track process does not automatically solve the issue of community acceptance. Anthony Roberts, a member of the New South Wales Legislative Assembly representing Lane Cove, described the project's cancellation as a "huge win" and a "common-sense win" for the local community. Commenting on the Facebook page of the Lane Cove Responsible Planning Group, Roberts stated that this victory sends a "clear message" to other developers: they must find suitable locations before putting proposals forward.

Roberts emphasized that while data centres play an important role in the modern economy, developments of this size and scale must be appropriately located and planned with the surrounding community in mind, rather than being placed in close proximity to residential homes.

FAQ: Sydney data centre project scrapped

Why was the Project Mars data centre cancelled?

Goodman Group withdrew the application due to intense community opposition and a changing regulatory environment. The project faced significant push-back because it was planned to be built only 20 metres from residential homes in Lane Cove, leading to a record number of negative submissions during the consultation period.

How much did the proposed data centre cost?

The proposed Project Mars facility was estimated to cost A$1.2 billion, which is approximately £630 million or $841 million. It was intended to be a 90-megawatt facility, representing a massive scale of investment in the Sydney suburb of Lane Cove.

What is the New South Wales fast-track programme for data centres?

The New South Wales government has introduced a programme to assess data centre applications within a 75-day window. To qualify, developers must meet specific standards and provide funding to support the additional supply of water and energy required by the infrastructure.

Why is Australia a target for AI data centres?

Australia is a global destination for data centre construction due to its abundance of clean energy, natural gas reserves, and available land. These factors make it an ideal location to support the energy-intensive infrastructure required by the rise of generative AI.

What does the Lane Cove outcome mean for future developers?

The outcome serves as a warning that developers must prioritize appropriate location and community planning. Local representatives have stated that the victory sends a message that large-scale developments must be situated in areas that do not conflict with established residential communities.
