A rare species of frog has defied scientific belief by hopping back from the brink - 30 years after it was thought to have become extinct.
The Yellow-spotted Bell Frog has been discovered in the NSW southern tablelands decades after scientists believed it had died out.
Environment Minister Frank Sartor said the discovery of the marbled green and gold coloured frog was a reminder of the importance of protecting natural habitats.
"I'm advised that finding this frog is as significant a discovery as a Tasmanian tiger," he said.
"This discovery is a reminder of the need to protect this environment so future generations can enjoy the noise and colour of our native animals."
Frogs' location a secret
A local fisheries conservation officer, Luke Pearce, stumbled across the frog while surveying a stream for endangered fish.
He returned with a herpetologist to find a thriving population.
The International Union for Conversation of Nature say that 30 to 50 per cent of amphibians are now threatened with extinction.
Mr Sartor said the location of the frogs will remain secret to ensure the survival of the species.
The government is currently in talks with Taronga Zoo in Sydney about developing a captive breeding program.
