Site attributes

Seventeen attributes, and exactly how far each one is proven

Four asset owners responded to a Before You Dig Australia enquiry on 26 August 2026, followed by a site inspection on 27 August. The results identify a substantial combination of energy, connectivity, land, climate and access advantages, with grid capacity, fibre diversity, water strategy and the energy precinct configuration now forming the four gating questions for feasibility, and planning running alongside. The NSW Guidelines page sets out how the same evidence reads against the seventeen performance measures.

Read the position column literally. “Confirmed” means an asset owner has confirmed the asset exists. It does not mean capacity, approval or service is secured, and nothing on this page should be read that way.

Where the evidence sits

4 Confirmed An asset owner has confirmed the asset exists. Capacity is a separate question.

5 Strong evidence Documented or measured, and consistent across more than one source.

2 Development opportunities Not a constraint. A design or commercial decision still to be made.

6 Verification priorities The open items, including the four gating questions. These govern the next stage of feasibility.

Site investment attributes, with the evidence position, the investor benefit, the current evidence and the next verification step for each
Attribute	Position	Investor benefit	Evidence and current position	Next verification	Detail
EnergyHigh-pressure gas	Confirmed	Potential on-site energy firming and generation pathway.	Jemena confirms the site could affect the high-pressure Eastern Gas Pipeline, identified as EGP Midline.	Confirm industrial offtake feasibility, capacity, pressure, connection cost and delivery timeframe.	Energy, for High-pressure gas
Energy132 kV power	Confirmed	Direct proximity to high-voltage infrastructure reduces the need for a long connection corridor.	Asset plates identify feeder 97R, Cooma to Bega, on double-circuit-capable poles, with the second circuit position vacant.	Obtain network-owner confirmation of voltage, configuration and feasible point of connection.	Power, for 132 kV power
EnergyGrid capacity	Verification priority	A confirmed staged connection could support development from an initial facility to a larger campus.	No firm rating or available capacity has been established for feeder 97R. A 114 MW wind generator already exports through the network.	Submit staged 25, 50, 100 and 200 MW load scenarios to the relevant network providers.	Power, for Grid capacity
ConnectivityCarrier fibre	Strong evidence	Existing carrier infrastructure may provide a faster and less costly route to high-capacity connectivity.	Telstra issued an explicit major-cable and optic-fibre warning. NBN separately identified communications assets.	Confirm dark fibre or wavelength availability, capacity, splice points, latency and commercial terms.	Connectivity, for Carrier fibre
ConnectivityDiversity	Development opportunity	Physically separate fibre paths would support carrier-grade redundancy and operational resilience.	One significant communications corridor is strongly indicated, but a diverse second route is not established.	Obtain route maps and feasibility responses from Telstra and at least one second carrier.	Connectivity, for Diversity
ConnectivityLatency	To be validated	Cooma’s position between Canberra, Sydney and Melbourne may suit regional compute and resilience workloads.	Geographic positioning is favourable, but carrier performance has not been measured.	Obtain indicative and tested latency to Canberra, Sydney and Melbourne network locations.	Connectivity, for Latency
SiteLand	Strong evidence	A large, predominantly clear holding supports flexible campus design and infrastructure separation.	Up to 837.7 hectares of predominantly open grazing land across 11 lots as supplied.	Confirm survey area, developable footprint, slopes, geotechnical conditions and environmental constraints.	The site, for Land
SiteScalability	Strong evidence	The landholding could accommodate staged construction, energy infrastructure, setbacks and future expansion.	The property provides substantial land relative to a typical data centre campus.	Prepare indicative 50, 100 and 200 MW campus layouts.	The site, for Scalability
SiteSite control	To be validated	Consolidated ownership or control can reduce acquisition complexity and improve delivery certainty.	The proposed site extends across 11 lots as supplied. Complete ownership and title evidence has not been presented here.	Verify ownership, title, easements, restrictions and control of every required lot.	The site, for Site control
SiteHighway access	Confirmed	Direct highway frontage supports construction logistics, heavy vehicles and ongoing maintenance access.	The Monaro Highway B23, classified as State road HW19, runs approximately 3.9 km through the holding.	Confirm intersection design, heavy-vehicle access and Transport for NSW requirements.	Access, for Highway access
OperationsClimate	Strong evidence	Cool conditions and elevation may reduce mechanical cooling demand, energy consumption and operating costs.	Cooma has an annual mean maximum temperature of approximately 18.2 to 19.4 °C at about 850 to 900 metres elevation.	Undertake hourly-temperature, free-cooling and indicative PUE modelling.	The site, for Climate
OperationsWater	Design opportunity	An air-cooled or low-water architecture could reduce dependence on a new large-scale water supply.	No large-scale water supply has been demonstrated. The requirement will depend on cooling design.	Compare air-cooled, closed-loop and hybrid cooling options and confirm operational demand.	The site, for Water
OperationsWorkforce	Regional advantage	Proximity to Cooma provides access to services, accommodation, emergency response and a regional workforce.	The site is close to an established regional centre and directly connected by the Monaro Highway.	Assess construction workforce, specialist technical labour, accommodation and training partnerships.	The site, for Workforce
DevelopmentPlanning	Verification priority	NSW provides established assessment pathways for major data centre developments.	The land is understood to be RU1 Primary Production, which is not a prescribed data centre zone. A specific pathway is required.	Obtain formal advice on permissibility, rezoning, planning proposal and State Significant Development pathways.	Planning, for Planning
DevelopmentResilience	Development opportunity	Power, gas, fibre, highway access and a large landholding provide ingredients for a resilient campus.	Several infrastructure systems are present or strongly indicated, but the complete redundant design is not established.	Prepare an integrated resilience design covering power, fibre, cooling, access and backup systems.	The site, for Resilience
SustainabilityRenewables	Strong potential	Solar, battery storage and low-energy cooling could support a competitive low-carbon campus proposition.	The site has substantial land, cool climatic conditions and access to regional energy infrastructure.	Model on-site solar, BESS, renewable power purchasing and grid-support options.	Energy, for Renewables
SustainabilityCommunity	Development opportunity	Regional investment, construction activity and infrastructure improvements could create measurable local benefits.	The project is at an early stage and no community-benefit program has been defined.	Develop local procurement, skills, environmental and community-engagement commitments.	Planning, for Community

How to read the positions

Confirmed means the asset owner has confirmed the asset is there. Strong evidence means it is documented or measured and consistent across sources. Development and design opportunity mean a decision is still open, not that something is wrong. Verification priority and to be validated are the genuine unknowns, and the two that govern the project are grid capacity and the planning pathway.

The key facts

What rarely sits on one holding, and what each fact does not yet establish

Land: up to 837.7 haAbout 2,070 acres across 11 lots as supplied. Room to investigate data halls, solar, storage and setbacks; the developable footprint is still to be established. The site →
Scale: 50 to 300 MWThe scale of data centre development being investigated, in stages. Not confirmed grid capacity. The opportunity →
Electricity: 132 + 66 kVBoth lines cross the holding on Lot 1, and regional wind already exports on the 132 kV. Available capacity is untested. Power →
