Australia's heritage sites will be centre stage when Sydney hosts a global cultural event in 2023.
Federal Environment Minister Sussan Ley on Wednesday announced Sydney would host the next global general assembly of the International Council on Monuments and Sites.
"Our hosting the general assembly aligns closely with our commitment to the management of 20 World Heritage properties - with more nominations on the way," she said.
The event isn't until September 2023, with organisers expecting international travel to have returned to normal and the pandemic to be under control.
The government expects the heritage forum to bring in millions of tourism dollars.
The Sydney Opera House, Hyde Park Barracks, Luna Park, and the Blue Mountains area will be visited by delegates.
They will also have the opportunity to visit other cities and regions before and after the general assembly.
