Certainty delivered. At gigawatt scale.
Ministerial engagement delivered at portfolio level
- Helia EHS is the originating developer and project director behind Project Cobra — one of South Australia's most significant proposed data centre developments, targeting up to 1.2 GW of potential capacity at Tungkillo, SA.
From site selection to shovel-ready
The demand for data centre infrastructure across Australia is accelerating, driven by AI workloads, hyperscale cloud expansion, and sovereign data requirements. Helia EHS has positioned itself at the front edge of this growth — not as a passive advisor, but as an active originator and developer of large-scale facilities.
- Origination and development of a 1.2 GW data centre campus in South Australia
- Direct engagement with tier-one global hyperscale technology operators
- Deep SA regulatory knowledge — PlanSA, SA EPA, AEMO, and Ministerial engagement
- Integrated EHS, environmental and commercial project management capability
- Active monitoring of the national data centre development pipeline
Formal expressions of interest secured from global hyperscale technology operators
SA Government engagement delivered at Cabinet, CGO, and Ministerial (AI & State Development) level
Project Cobra
Site & Location
Multiple lots at Tungkillo, South Australia — approximately 75 km from Adelaide's CBD. The assembled site encompasses dedicated data centre lots, Battery Energy Storage System (BESS) land, and solar rights — enabling a fully integrated renewable-powered campus.
Site & Location
Up to 1.2 GW of potential data centre power capacity — comparable to the largest proposed hyperscale campuses in Australia. Integrated co-located Battery Energy Storage System and solar generation rights provide a compelling clean-energy value proposition for operators.

Hands-on development experience
Helia EHS has served as the originating project director on a 1.2 GW data centre proposal — giving us direct experience of every approval, commercial and technical challenge that large-scale developers face in the Australian market.
Deep South Australia capability
We have navigated PlanSA, the SA EPA, the Office of the Chief Government Officer and Ministerial engagement for data centre development — a regulatory environment, and the people within it, that we know intimately.
Connected to the hyperscale ecosystem
Our work on Project Spark brought us into direct engagement with global tier-one hyperscale operators, energy developers including Neoen, and grid specialists. We bring that network to every client relationship.
Integrated EHS and commercial lens
Our team combines technical EHS depth with commercial project management — meaning we understand both the environmental obligations and the investment pressures that drive data centre development timelines and decision-making.
Live market intelligence
We actively monitor the Australian data centre pipeline — including AirTrunk, Firmus, CDC Data Centres, IREN, and the SA and NSW planning and environmental approval portals — providing clients with a current, grounded view of the competitive landscape.
Certainty delivered
Our brand promise reflects our approach to data centre work: reducing ambiguity, managing risk proactively, and delivering the certainty that investors, operators and government agencies need to commit to major infrastructure.
South Australia's data centre moment
South Australia is emerging as a serious data centre location — driven by renewable energy advantages, available land, government support for AI infrastructure, and accelerating national demand. Helia EHS is tracking the full SA and national pipeline in real time.
