The men's Twenty20 World Cup that was due to be played in Australia later this year will now be played in 2022.
It comes after the ICC announced in July that the World Cup would have to be moved from its October-November slot this year due to the coronavirus pandemic.
The tournament, now being held in October and November of 2022, will come after another men's T20 World Cup in India from October 17 to November 14 next year.
Cricket Australia said pushing the 2020 edition back two years meant fans of teams from around the world should be able to go to games.
"This decision gives Australia something to look forward to in 2022. It also gives us a good chance of safely welcoming fans into the outstanding venues across the country to enjoy watching the world's best cricketers compete in this major global event," Cricket Australia chief executive Nick Hockley said.
"We would like to thank our government partners and venues for their continued support and we are working closely with them to retain the same host city and venue footprint established for the 2020 tournament, to the fullest extent possible."
All the teams that qualified for the 2020 men's tournament will play in 2021 in India, but there will be a new qualifying process for the 2022 World Cup.
People who had tickets for the 2020 games will be refunded in full, with a revised schedule to be announced.
Coronavirus has also forced the women's 50-over World Cup that was slated for 2021 in New Zealand to move to a February-March 2022 schedule, with the remaining qualifying games to be played in 2021.
"There has been no women's international cricket played since the conclusion of the ICC Women's T20 World Cup earlier this year and due to the varying impact of COVID-19 globally, that is likely to remain the situation for a number of the teams," ICC chief executive Manu Sawhney said.
"Moving the event by 12 months gives all competing teams the chance to play a sufficient level of cricket ahead of both the qualification event and leading into a Cricket World Cup so the integrity of the tournament is maintained."
