Ticket sales for this weekend's AFL matches in Melbourne are on hold while the Victorian government decides if the latest COVID-19 outbreak will impact crowd sizes at sporting events in the city.
The government on Tuesday announced new restrictions, but the AFL is hopeful fans can still attend Friday night's highly-anticipated top-two clash between the Western Bulldogs and Melbourne at Marvel Stadium.
The AFL announced on Tuesday morning it would pause ticket sales for games in round 11 and 12 while it awaits further directions.
Acting premier James Merlino said authorities were reviewing the situation surrounding sports crowds.
"For footy crowds and for other events there will be a public events advisory panel which will advise of any changes - we're not making any announcements today," Merlino said.
