The recommendation has generated a flurry of action from the Australian government, with Sussan Ley, the environment minister, stating she had already called Unesco's director-general, Audrey Azoulay, along with Foreign Affairs Minister Marise Payne. Experts say that if the committee follows the suggestion, it will be the first time a natural world heritage site has been listed as "at-risk" due to climate change consequences.
