The World Health Organisation has said vaccine mandates should be a "last resort" as the fallout from the Novak Djokovic saga continues.
The comments come after Djokovic attempted to enter Australia to play tennis without proof of being vaccinated against Covid.
All eyes are now on Australian Immigration Minister Alex Hawke on whether the world tennis number one will be allowed to stay in the country for the Australian Open.
But WHO's health emergencies programme executive director Dr Mike Ryan has warned against hard-line stances like Australia's position on vaccine mandates.
"We see mandates as a last resort … in the face of a large epidemic," he told Nine Newspapers.
