What we do

Karst Areas of Australia Under Threat

Nullarbor: largest arid karst area in the world, under threat from industrialisation via hydrogen and ammonia production, over grazing.

Daly, Wiso and Barkly areas: under threat from fracking, and over extraction of water from the underlaying aquifer.

Eneabba WA: threatened by renewables, wind and solar farms

Kentbruck Vic: between Mt Gambier and Newer Volcanics: threatened by wind farms.

Where we do it

Nullarbor in the News

A recent exploration trip by members of the Australian Speleological Federation, working with academics from the University of Adelaide have made major discoveries on the Nullarbor. Their combined work has proven the Nullarbor is a biological hot spot and that it is in need of protection in its entirety.

The proposed industrialisation of the Western Australian side poses significant environmental destruction of a landscape that holds important internationally recognised values, equal to that of the Great Barrier Reef.

The Kentbruck Wind Farm has been approved by the Victorian Minister for Planning, Sonia Kilkenny. The Ministers decision was released 6 January 2026.

This wind farm will impact the habitats of the critically endangered Southern Bent-wing bat, the Australasian Bittern and Brolgas.

The Kentbruck Wind Farm is still before the federal Department of Environment, Climate Change and Energy.

For media coverage of the complexities of this development, see: ABC: When green energy threatens what it is meant to save.

New evidence shows a reduction of feral horse numbers in Kosciuszko National Park, down from approximately 17,000 to 3000 after the NSW government allowed aerial culling to be used and repealed the NSW Heritage Horse Act. These actions by the NSW government came after prolonged actions of scientists, conservationists and the Australian Speleological Federation.
