Nasdaq listed IREN unveils AU$10 billion, 900MW data centre plan for Wagga Wagga, escalating local and grid debate

IREN, a Nasdaq listed AI cloud and neocloud operator, on October 14 released early plans for a 900 megawatt data centre campus dubbed Redbank near Gregadoo, on the outskirts of Wagga Wagga in New South Wales. The company said the development would be built in stages over several years, could cost more than AU$10 billion and is targeting initial energisation in 2029. IREN has begun community consultation and intends to lodge a scoping report with state planning authorities later this month.

How Redbank fits into a rapidly changing local picture

The IREN proposal arrives amid a flurry of large infrastructure plans for the Wagga Wagga region. Earlier this month CDC Data Centres sought planning clearance for a separate, larger campus at Gregadoo with capacity estimates of up to 1.4 gigawatts and a headline development cost of about A$15 billion. Together the two proposals would add more than 2.3 gigawatts of prospective demand in a single regional area, a scale that has drawn attention from planners, grid operators and local communities.

Developers and investors see regional New South Wales as attractive because of available land, existing transmission corridors and the opportunity to deliver large, contiguous campuses at scale. For IREN, the Redbank site sits near existing transmission infrastructure and would be delivered in phases, a company representative told local stakeholders during initial briefings documented on project materials made public in October.

Grid, water and community concerns rise alongside investment promise

Big data centre projects promise major local spending on construction, jobs and long term rates revenue for councils. IREN estimates the project could mobilise more than AU$10 billion in development spending across the build phases, and similar megaprojects in the Riverina have been framed by proponents as a way to attract private infrastructure capital to regional Australia.

At the same time, the proposed scale has heightened concerns about practical constraints. Independent reporting and local council records show questions about whether the regional grid can accommodate an additional gigawatt scale load without substantial transmission upgrades. Grid operator planning documents published this year have flagged Wagga and surrounding areas as potential hosts for large new loads, but any connection at this scale would require multi year upgrades, formal connection agreements and coordination with TransGrid and the NSW planning system.

Water availability and local amenity are also attracting scrutiny. Community groups in Gregadoo and Wagga Wagga have already begun organising in response to the CDC proposal, and local residents described feeling blindsided when plans for multiple large campuses emerged. IREN has begun community consultation and its scoping materials will need to address water usage, backup power arrangements, noise, traffic and biodiversity impacts as part of the NSW planning regime.

Regulatory path and timing

IREN says it will lodge a scoping report with the NSW Department of Planning, Housing and Infrastructure at the end of October. That filing is an early formal step that triggers public exhibition periods and technical assessments. A scoping report and subsequent environmental impact studies typically require months of consultation and assessment, and major projects can take several years to secure all necessary land, transmission and environmental approvals.

Project timelines given by IREN and observed in similar developments suggest initial energisation could be targeted for 2029, but that hinge on securing grid connections, planning consent and financing. Industry analysts caution that large data centre projects face complex commercial and permitting risk, especially when multiple developers compete for the same regional transmission capacity.

Why this matters for investors, policy makers and regional Australia

The twin announcements in Wagga Wagga underline the rapid pace of expansion in demand for AI ready compute and hyperscale data centre capacity. For investors and listed developers such as IREN, securing shovel ready sites, long term offtake customers and grid access is central to valuations and future revenue streams. For policy makers and energy planners, projects of this scale force trade offs between accelerating digital infrastructure and managing the physical constraints of electricity networks, water resources and local communities.

For regional economies, the projects present both opportunity and risk. Large scale construction programmes can deliver jobs, contract work and a broader economic stimulus, but local governments and residents are increasingly conditioned to insist on binding community benefits, transparent environmental mitigation and guaranteed funding for necessary infrastructure upgrades.

As IREN moves from consultation to formal planning filings, the project will join an intensifying national discussion about how Australia manages the surge in demand for compute heavy infrastructure. The coming months will test whether regulators, grid operators and developers can align permits, transmission upgrades and community expectations in time for the ambitious 2029 energisation target.

IREN and NSW planning authorities will be watched closely by investors, rival developers and regional stakeholders as the Redbank scoping report and consultation process progress through October and into 2027.
