The Queensland government has extended an invitation to Hollywood star Leonardo DiCaprio to visit the Great Barrier Reef and learn about its conservation efforts.
DiCaprio this week cited the plight of the reef at the Our Oceans Conference in Washington DC.
He told the gathering over 600 miles (965km) of reef previously "teeming with life" had been devastated in an unprecedented coral bleaching event.
"We are seeing this level of impact to coral reefs around the world from Hawaii to the Florida Keys, from Madagascar to Indonesia," he said.
Deputy Premier Jackie Trad on Saturday extended an open invitation to the actor to visit the reef.
"He can come any time he likes, he's absolutely welcome to come to Australia, to come to Queensland and to come to the Great Barrier Reef," she said in Brisbane.
"I know he's been there before and I really applaud his passion and his commitment to conserving and protecting the earth's oceans."
The reef remains at risk of being placed on UNESCO's "in danger" list - a move that would be both embarrassing for the state and federal governments and economically damaging to the tourism industry.
The Queensland government last month declared it would take reef protection to the next state election as a major platform after its tree-clearing laws were defeated on the floor of the hung parliament.
Labor linked that bill to the reef's health, given vegetation management can influence sediment in-flows.
UNESCO is due to review Australia's progress on its Reef 2050 plan later this year.
