The return of athletes and officials to Australia after the Tokyo Olympics could lead to a loosening of travel restrictions for people who have been vaccinated against COVID-19, the Australian team's medical director said on Tuesday.

Australia will be sending about 480 athletes to Japan for the games in July and August and they, along with more than 500 officials and media, will be forced into mandatory hotel quarantine for 14 days when they get back home.

Dr. David Hughes told a media briefing that such a large group would provide the government with a good idea of the risk of community infection from vaccinated people entering the country.
