Morrison said earlier on Wednesday that unvaccinated players would be free to compete in the grand slam after a two-week Covid-19 quarantine, provided Victoria, who hosts the tournament in Melbourne, has applied for permits for them.
Andrews said his state would not make such applications.
“On behalf of every vaccinated Victorian who has done the right thing, my government will not seek an exemption for unvaccinated players,” he told reporters.
“If we don’t apply for a waiver, no waiver will be granted and the whole issue is basically resolved.”
Australia’s borders have been effectively sealed for 18 months due to the Covid-19 pandemic, although authorities approve travel waivers for special cases.
Victoria is the hardest hit state in Australia, with the capital Melbourne locked six times. The sixth lockdown ended on Friday, but only for fully vaccinated adults.
Unvaccinated adults will continue to be banned from pubs, restaurants, sporting events and other parts of the economy and may be locked out well into 2022.
Victoria’s position is a blow to the organizers of the grand slam, Tennis Australia, who want a strong field for the tournament in January.
Some top players, including defending champion Novak Djokovic, have refused to disclose their vaccination status. The world number one said last week that he may not play at the tournament “as they are”.
Morrison had previously told Seven Network that unvaccinated players should be quarantined for two weeks.
“All the rules should apply to everyone,” he said.
“Whether you’re a grand slam winner, a prime minister or a business traveler, a student or whoever. Same rules.”
Morrison’s comments contradicted those of his immigration secretary Alex Hawke, who last week said tennis players and other athletes would need to be double vaccinated to enter the country.
Professional athletes in Victoria are under a vaccine mandate, which also covers coaches, officials, media and other personnel involved in elite competition.
Andrews said tennis players should be held to the same standard as everyone else at the event.
“I’m not going to demand that people who sit in the stands, people who work at the event, be vaccinated while players are not,” he said.
Currently, about 70% of the top 100 tennis players for men and women have been vaccinated.
If Djokovic does play at Melbourne Park, he will be the favorite to win a 21st men’s grand slam title, a record, taking him out of a draw with Roger Federer and Rafa Nadal.
