Stockland and John Boyd Properties have removed a proposed data centre from the revised Concept Masterplan for the former Kogarah Golf Club site at Arncliffe in southern Sydney, according to ABC News. The Stockland data centre would have been a four-storey, 25,400-square-metre facility on a site of roughly 18.3 hectares beside the Cooks River.
A second Sydney project fell away at the same time, though the reports treat it as a separate story. AirTrunk will not proceed with a proposed 140MW data centre at 16-20 Mars Road, Lane Cove West, next to its SYD2 campus. For anyone who buys cloud capacity in Sydney, the pair of decisions raises a fair question about where the next round of local supply will come from.
This analysis sorts what the outlets have confirmed from what they have not, then looks at what it means for the Sydney market, for enterprise cloud planning and for developers who want to build near the airport. It sits against a backdrop we covered earlier, when we tracked the A$141 billion data centre pipeline heading into the Australian construction queue.

Stockland data centre removed from the Arncliffe masterplan
The core facts are short and well sourced. Stockland and John Boyd Properties lodged an amended Concept Masterplan for the former Kogarah Golf Club site. The amended plan drops the data centre and keeps the logistics precinct. ABC News and the Sydney Morning Herald both carried the story on 8 November, and Bloomberg ran its own report under a headline that framed the move as plans scrapped as community pushback grows.
The wider redevelopment carries an estimated price tag of around A$3.5 billion, according to the ABC. Stockland now describes the project as a world-class logistics precinct that does not include a data centre. The company has not, in the statements reported so far, said the decision came from opposition. Reports describe the choice as a business decision to put the logistics hub first, while the same reports also describe sustained community backlash.
That distinction matters for how readers should treat the headline version of this story. A headline that says Stockland dumped the project after protests captures the public mood, yet Stockland has not confirmed that cause. We use the verified wording throughout this piece and flag where outlets draw their own conclusions.
What the revised Kogarah Golf Club plan now contains
The amended masterplan carries a package of public benefits. It includes a proposed one-kilometre public foreshore link along the Cooks River, the future delivery of the 14-hectare Pemulwuy Park, local road upgrades and improved active-transport connections. The ABC and the Sydney Morning Herald both listed these items in their coverage.
The table shows how little else moved. The land area and the project value are unchanged in the reports, and the public benefits sit alongside the logistics plan. The only line item that disappears is the data hall. That suggests the data centre was a removable module of the plan and not the load-bearing piece, which is useful context when judging how hard Stockland fought to keep it.
AirTrunk walks away from Lane Cove West
On the north shore, AirTrunk confirmed it will not proceed with a proposed 140MW data centre at 16-20 Mars Road, Lane Cove West. The site sits next to the operator’s existing SYD2 campus. Reports say SYD2 and the approved Apollo Place building will still be completed, so the decision trims the footprint of the campus without halting it. AirTrunk lists its Australian locations on its own Australia locations page.
AirTrunk gave a technical reason in comments reported by Capital Brief. The company’s spokesperson said the Mars Road site’s steep terrain and limited scale made it technically unsuitable for the type of facility its customers need, and that the company is now focusing on better-suited sites including Kurri Kurri and Mickleham. In a separate statement carried by local outlet In the Cove, the spokesperson said that process has lapsed, so there will be no environmental impact statement and no community consultation for that site.
Read together, the statements point to a land-fit and portfolio decision. AirTrunk has not said community opposition drove the call. The reasons it gave concern the site and its customers, not the neighbours.
Two projects, two reasons, no confirmed link
It is tempting to read the two decisions as one story. Both involve Sydney data centres, both surfaced in the same news cycle, and both leave local residents with one fewer proposal to oppose. The available reports do not support a stronger claim than that.
No outlet has reported that Stockland and AirTrunk coordinated their moves. No outlet has reported that AirTrunk was involved in the Arncliffe project. The reports identify the Arncliffe proposal and the Lane Cove West proposal as separate developments, run by different companies, in different suburbs, with different stated reasons. We treat them that way here.
How the community campaign shaped the Arncliffe debate
The Arncliffe proposal drew organised resistance. The community group Stop the Cooks River AI Project, known as SCRAP, opposed the data centre, and the ABC reports that its members include hundreds of residents. A SCRAP representative called the outcome a victory for people power, as quoted below.
What residents raised
The ABC reported that campaigners and a local councillor pointed to energy use, water, noise and the ecology around the Cooks River as their main worries. Those are the standard objections to any large data hall near housing. They also explain why campaigners focus on the river corridor, since the foreshore link and Pemulwuy Park are the parts of the plan that residents will actually use.
What Stockland said
Stockland’s public line stresses location and use, not opposition. A spokesperson told reporters the site suits a logistics hub because of its proximity to Sydney Airport, Port Botany and major transport infrastructure, and that it could also host mixed uses such as retail and hospitality. The company said it will keep engaging with stakeholders as planning for the precinct continues, according to the ABC.
The same pattern is playing out in other states. Readers tracking the politics can compare it with the Tungkillo protest in the Adelaide Hills, where a large proposed campus also met organised local resistance.
What the companies and campaigners said
Five on-the-record statements frame the story. Each is reproduced verbatim from the verified quote file for this report.
A Stockland spokesperson explained the logistics rationale to the Sydney Morning Herald: “The site is on the doorstep of Sydney Airport and in close proximity to Port Botany and major transport infrastructure, making it uniquely suited for a logistics hub and has potential for mixed uses, like retail and hospitality.”
The same spokesperson described the amended plan to Sydney Dispatch as a “World class logistics precinct which does not include a data centre as part of the amended Concept Masterplan.”
A representative of Stop the Cooks River AI Project told the ABC it was a “Victory for people power.”
An AirTrunk spokesperson told Capital Brief: “AirTrunk will not proceed with the proposed Mars Road site. Following due diligence, the site’s steep terrain and limited scale, make it technically unsuitable for the type of facilities our customers need. We’re focusing on better-suited sites, including Kurri Kurri and Mickleham.”
Another AirTrunk spokesperson statement, reported by In the Cove, read: “After Stage 5 is complete, AirTrunk has no plans for further development in Lane Cove. We previously undertook preliminary planning work for a possible site at Mars Road, but that process has lapsed. We will not proceed with the proposal, so there will be no EIS or community consultation for that site.”
The contrast is plain. The two companies talk about land, customers and logistics. The campaigners talk about people. Both framings can be accurate at once, which is why the story resists a single headline.
Why a data hall was ever pitched beside Sydney Airport
The logic is easy to see on a map. Arncliffe sits close to Sydney Airport and Port Botany, which gives it strong road and freight access. Developers who hold a large, flat, rezoned parcel in that corridor have two obvious tenants: warehouses and data halls. Both want good transport links, reliable utilities and proximity to a large customer base.
For cloud and AI operators, land in the inner south is scarce. Sydney is a crowded market, and the DatacenterMap directory lists 103 Sydney facilities from 28 operators. A new site within reach of the airport and the city grid would have been a prize, which helps explain why the Arncliffe pitch included a data centre in the first place.
A data centre also asks more of a neighbourhood than a warehouse does. It brings heavy power demand, cooling and sometimes backup generation. When the site abuts a river that locals are working to restore, the argument for an industrial-scale compute hall gets harder to make. Stockland’s decision to lead with logistics sidesteps that fight while keeping the A$3.5 billion project moving.
Market impact on Sydney cloud capacity
Two cancelled proposals do not shrink Sydney’s installed base. The 103 listed facilities stay where they are, and AirTrunk’s SYD2 campus and Apollo Place building continue. What shrinks is the pipeline of future supply, and in a market where operators plan years ahead, that pipeline is what sets pricing and availability for new enterprise contracts.
The most direct effect lands on AI workloads. The Arncliffe site was described in coverage as an AI data centre, and large AI clusters need exactly the dense power and cooling that sites like this offer. With 140MW off the table at Lane Cove West, and a four-storey hall off the table at Arncliffe, inner-Sydney capacity for those workloads will tighten unless projects elsewhere move faster.
AirTrunk has already pointed to where it wants to build instead. Its spokesperson named Kurri Kurri and Mickleham as better-suited sites. That points to a shift toward larger parcels on the edges of Sydney and in other markets, which usually brings lower land costs but different network paths. Our earlier piece on how few Australian AI data centres have secured power shows why site choice now turns as much on grid access as on land.
What cloud buyers should check now
Most Australian teams consume cloud through the big public regions, so the immediate effect is small. Still, a tighter local pipeline is a reason to review three things. First, check whether your AI training or inference jobs need Sydney placement, or whether another region meets your latency needs. Second, review your contracts for capacity commitments, because operators may pass on higher costs for new builds. Third, confirm where your regulated data must live.
That third point links to policy. State and federal agencies keep tightening rules on where government and regulated data may sit. The NSW government’s cloud rules, which we summarised in our note on the NSW cloud circular and its mandatory rules, are one example. If local supply tightens while residency rules harden, teams with sensitive workloads have less room to move.
Historical context: from fast-track to local vetoes
Sydney’s data centre debate has shifted in tone over the past year. Early pitches leaned on investment and capability. Recent coverage has shifted toward local opposition and parliamentary scrutiny. The ABC calls the Arncliffe outcome the latest in a series of proposed data centres scrapped after community opposition.
The pattern is not unique to New South Wales. In Victoria, councils have pushed for a pause, as we reported in our story on the Victorian councils’ data centre moratorium push. Overseas, the same backlash has become a campaign issue, which we examined in our look at the US data centre backlash and its Australian angle.
The Bayside councillor quoted by the ABC argued that councils should have more of a veto over these projects. That is a political argument and not a settled rule, though it shows where the next round of lobbying will aim.
Policy pressure in New South Wales
The ABC reports that the Minns government released a data centre policy framework in August, which it said balances household interests with investment. A parliamentary inquiry has since reported on data centres. According to the ABC, that report said guidelines should have existed before any planning fast-track for these projects, and the government has until February next year to respond.
Those two documents set the terms for what comes next. If the response tightens consent rules, developers like Stockland will keep treating data centres as optional add-ons to larger precincts. If it loosens them, operators may regain confidence to propose inner-city sites. Either way, the Arncliffe and Lane Cove West outcomes now sit in the record as examples both sides will cite.
Federal energy debate adds another layer. Our analysis of data centres and the grid under Chris Bowen’s firm-power push explains why power access is as decisive as planning approval.
Five predictions for Sydney data centres
These are our own judgements based on the reported facts, not confirmed plans from any company.
- Developers will split data halls from precincts. Stockland showed that a mixed-use plan can shed its data centre and keep its value. Expect other landholders to pitch logistics or industrial uses first and add compute later, if at all.
- Operators will chase bigger, emptier sites. AirTrunk’s naming of Kurri Kurri and Mickleham suggests the industry is moving toward parcels where terrain, scale and neighbours are less contentious.
- Community groups will copy the SCRAP model. A small, organised group forced a national story. Other suburbs facing proposals will study how it ran its campaign.
- Inner-Sydney AI capacity will stay tight. With fewer new inner-city halls, enterprise buyers will see longer lead times for dense AI clusters near the CBD.
- The February government response will set the tone. A firm response on guidelines and fast-track rules could settle the question for a while. A weak one will invite more local fights.
None of these predictions needs a dramatic change in policy. They follow from incentives already visible in the Stockland and AirTrunk statements.
Signals to watch next
The first row is the quickest to resolve. A formal lodgement would put Stockland’s wording into planning documents, which is harder to walk back than a spokesperson’s statement. The third row is the one with the biggest market weight, because it tells operators and customers where the next Sydney-area capacity will actually land. We track these shifts across our cloud computing coverage.
FAQ: Stockland, AirTrunk and Sydney data centres
What did Stockland remove from the Arncliffe plan?
Stockland and John Boyd Properties removed a proposed four-storey, 25,400-square-metre data centre from the revised Concept Masterplan for the former Kogarah Golf Club site at Arncliffe. The site is about 18.3 hectares, and the wider project is estimated at around A$3.5 billion, according to the ABC.
Did community opposition cause Stockland to drop the data centre?
That is not confirmed. Stockland reportedly described the move as a business decision to prioritise the logistics hub, while reports also describe sustained community backlash. The group Stop the Cooks River AI Project opposed the proposal and called the result a victory for people power.
What is happening with AirTrunk at Lane Cove West?
AirTrunk will not proceed with a proposed 140MW data centre at 16-20 Mars Road, Lane Cove West, next to its SYD2 campus. SYD2 and the approved Apollo Place building are to be completed.
Are the Stockland and AirTrunk decisions connected?
No report says so. The outlets identify them as separate proposals by different companies in different suburbs. No source claims coordination or an AirTrunk role in the Arncliffe project.
Why did AirTrunk say it was leaving the Mars Road site?
An AirTrunk spokesperson told Capital Brief that the site’s steep terrain and limited scale make it technically unsuitable for the facilities its customers need. The company said it is focusing on better-suited sites including Kurri Kurri and Mickleham.
What will replace the data centre at Arncliffe?
Stockland describes a world-class logistics precinct near Sydney Airport and Port Botany, with potential for mixed uses such as retail and hospitality. The revised plans also include a proposed one-kilometre public foreshore link along the Cooks River, the future delivery of 14-hectare Pemulwuy Park, local road upgrades and improved active-transport connections.
Does this affect my cloud services in Sydney?
Not directly. Existing Sydney facilities keep running, and AirTrunk’s SYD2 and Apollo Place continue. The change affects future supply, so teams planning large AI deployments or regulated workloads should check capacity commitments and data residency options early.
