The Great Barrier Reef will not be listed as endangered but will remain under watch because of "major threats" to its health, a draft recommendation to the UN's World Heritage Committee says.
The Australian federal and Queensland governments have welcomed the draft report Unesco released on Friday. Environment Minister Greg Hunt called it "an overwhelming endorsement" of their approaches to reef protection.
But environmental groups say the report puts both governments on notice to deliver on their promises to protect the reef.
The UN's conservation agency noted "with concern" the state of the reef, which has had World Heritage Site status since 1981.
Unesco warned the reef's "overall outlook is poor" and urged Australia "to rigorously implement all its commitments" and submit a progress report by December next year.
