Unvaccinated tennis stars are set to be allowed to play in the Australian Open but face two weeks of hard quarantine and regular testing, according to a letter distributed to WTA players.
But the WTA players' council says it has been told all competitors will be able to go to Melbourne in January.
It said Tennis Australia thought entry rules would "improve significantly".
Last week, Victoria Premier Daniel Andrews said he did not think an unvaccinated tennis player would be given a visa to enter Australia.
A significant number of tennis players - including 35% of those on the men's ATP Tour - remain unvaccinated.
