The state government in New South Wales wants a World Heritage listing for Australia's oldest national park.
Environment Minister Robyn Parker says the state will nominate the Royal National Park, on the southern outskirts of Sydney, for the listing.
"Royal National Park was the first national park to be declared in Australia in 1879, only the second in the world, and is the most visited national park in NSW," Ms Parker said in a statement on Monday.
The park was added to Australia's National Heritage list in 2006.
AAP reports Heathcote National Park and the Garawarra State Conservation Area, south of Sydney, will also be put forward for World Heritage listing.
If successful, they would join 19 other Australian sites on the World Heritage list, including the Sydney Opera House, the Great Barrier Reef and the Blue Mountains.
