The global energy giant, InterContinental Energy (ICE), announced a major development for the West Australian side of the Nullarbor in 2021. The development, known as the Western Green Energy Hub, (WGEH), aims to produce a huge 50 gigawatts of green energy, a capacity about 12 times the size of the current West Australian power grid.
This development is not for the production of electricity to help supply the WA power grid, but to produce hydrogen and ammonia, all for export.
The problem is that this development will IRREVERSIBLY DESTROY the ecosystems, the heritage values and the caves found on the biggest piece of arid karst on earth.
Potential destruction of the largest karst & cave systems on earth:
The Nullarbor
Energy for Export
Planed hydrogen and ammonia industry for the Nullarbor.
Solar and Wind farm plans for the Nullarbor Plain have now been sent to the Federal Dep't of Climate Change, Energy, Environment and Water.
Public consultation closed 7th of February 2025.

Watch our film showing the environmental values of the Nullarbor
The Nullarbor's fragile topsoil is held together with a biofilm stabilised by delicate biological crusts formed from lichens and bacteria which, if disturbed, creates a dust bowl.
BULLDUST
The Nullarbor is an integrated landscape, which means that any disturbance of the surface affects many aspects of the whole system. The building of roads and burial of cables for example affects surface drainage, creating soil movements and sediment flows, that can then block underground cavities. This in turn impacts the caves air flows, humidity and the habitats of cave biota.
What will happen if these developments go ahead?
Why is the Nullarbor so valuable?
It is not just desert
The Nullarbor contains the largest single exposure of arid limestone bedrock in the world occupying an area of around 250,000 square kilometres.
It is underpinned with spectacular caves with saline lakes and halite formations metres in length. The surface records: ancient sand dunes, pocket valleys, ancient river beds (paleochannels) and ancient reefs.
The values that the Nullarbor holds, cultural, and natural meet seven World Heritage Criteria, yet the Nullarbor has little legislative protection on the WA side, with a range of protections, a National Park, A Wilderness Protection Area and Regional Reserve on the SA side.
Its Caves and surface also record significant cultural heritage dating back 30,000 years
Let's put the Nullarbor Caves & Karst on the
National and World Heritage Lists
This process will take time and money.
$50,000 is required and we need your help.
Tax-deductible donations can be made to the ASF’s Nullarbor Campaign via the Karst Conservation Fund.

The ASF acknowledges Aboriginal and Torres Strait Islander peoples as the traditional owners and custodians of the land, rivers, and sea on which we live, and we pay our respects to their Elders past, present and emerging. We acknowledge and respect the deep spiritual connection that Aboriginal and Torres Strait Islander people have to Country, especially to caves.
