More than one-in-ten of Australia's shark, ray and ghost shark species are at risk of extinction, with experts warning 'urgent action' is needed to stop severe population declines.
The new data comes from the first complete assessment of extinction risk, showing Australia is home to more than a quarter of the world's shark species, 12 per cent of which are at risk.
'While Australia's risk is considerably lower than the global level of 37 per cent, it does raise concern for the 39 Australian species assessed as having an elevated risk of extinction,' the study's lead author Peter Kyne says.
Great white sharks (pictured) are doing better than many other Australian shark species, some of whom face possible extinction, according to the new Action Plan for Australian Sharks and Rays.
'Around Australia, many of our threatened sharks and rays are not commercially important so these are largely 'out of sight, out of mind', but they require protection at national, state and territory levels.'
For iconic species such as the great white shark and grey nurse shark, Dr Kyne said there are 'positive signs' protection and management is working, although they remain threatened.
Commercial fishing that affects sharks both as a targeted species and bycatch for industries such as tuna remains a 'major threat' facing sharks around the world, Dr Kyne said.
