The MCG Ashes Test and the Australian Open will be watched by capacity crowds following the easing of coronavirus restrictions in Victoria.
Victorian premier Daniel Andrews has announced there will no longer be limits on gatherings in the state.
Andrews had revealed last month, when the latest lockdown ended, that he was hopeful at least 80,000 will be able to attend the Boxing Day Test.
Australia and England can now look forward to playing in front of a full house of 100,000 next month.
The first grand slam of the year, starting at Melbourne Park on January 17, is also set to be played without a cap on the number of spectators allowed in.
"Whether it's 100,000 people at the MCG on Boxing Day or a smaller group of people standing up at the … local pub, this is the COVID-normal that every Victorian has built," he said at a press conference.
Crowds for the 2021 Australian Open were limited to 30,000 people per day – around half capacity – prior to a snap lockdown being implemented during the tournament.
No more than 30,000 were permitted in the MCG for Australia's Boxing Day Test against India last year.
