Over 110 countries at the World Health Assembly on Monday night agreed to an international probe into the coronavirus pandemic.
Australia led the push for the independent resolution calling for an impartial, independent and comprehensive investigation and evaluation of the international response to the pandemic.
Health Minister Greg Hunt said the inquiry needs to protect against the health risks of wildlife wet markets and include all populations.
"We need to learn the lessons from this pandemic and ensure we have the strongest possible global health architecture, with an enhanced ability to prevent and respond to future outbreaks," he said at the assembly.
WHO director-general Tedros Adhanom Ghebreyesus promised a review would come "at the earliest appropriate moment".
Chinese President Xi Jinping also supported the WHO-led review and said, "This work needs a scientific and professional attitude, and needs to be led by the WHO. And the principles of objectivity and fairness need to be upheld."
His comments come as China's commerce ministry announced all Australian barley imports would be hit with 80.5 per cent tariffs from Tuesday.
