A group of scientists has voiced dismay at a federal decision to disregard any heritage value of Western Australia’s Nullarbor Plain in considering a $100 billion wind and solar project proposal.
The Western Green Energy Hub would build 3000 wind turbines and six million solar panels in WA to power production of hydrogen and ammonia, mostly for export, though potentially leaving some for local use.

The project would start at the South Australian border and stretch west along the Nullarbor for hundreds of kilometres near the world’s largest arid limestone karst system, which Save the Nullarbor scientists describe as “a spectacular hidden world of ancient caves and rock holes of staggering dimensions, beauty, scientific values, and priceless cultural importance”.
A delegate of federal Environment Minister Tanya Plibersek has determined the project will require a full assessment of its impact on three criteria: threatened species, migratory species and the Great Australian Bight Marine Park.
But there is no order to assess the impact on two more criteria: World Heritage and National Heritage impacts.
Save the Nullarbor says this “almost ensures the development will proceed without appropriate scrutiny” and represents the Minister “abrogating responsibility” under World Heritage laws.
They point to a 1992 Commonwealth-commissioned report and, more recently, a 2022 report by the Wilderness Society and Sea Shepherd Australia showing the area has world heritage significance.
The WA government of 1992 did not support the World Heritage nomination, so did not proceed; by contrast, the SA government made a 2022 election commitment to secure World Heritage protection for its side of the Nullarbor and Great Australian Bight.
Save the Nullarbor says both sides share the outstanding universal values and allowing damage or alteration before appropriate verification work could breach Australia’s legal responsibilities under the World Heritage Convention.
