The Bledisloe Cup contests between Australia and New Zealand will be reduced to two Tests each year until at least 2025.
The competition has always involved three games every year since 2006 but now with the World Cup scheduled in 2023 and the Wallabies set to face British and Irish Lions at home in 2025, Rugby Australia chief executive Andy Marinos said they are exploring options to play more against different countries.
"We need to manage and prioritise how we're going to go to the (2023) World Cup and then we have a (British and Irish) Lions year in 2025, which is also another consideration," he told Fox Sports.
"We've played each other a huge amount over the years and we haven't been successful -- it's not because of that we're not wanting to look at it.
"But we feel for a period it'll be good to have a break and look at other opportunities against other countries."
The last time Australia won the Bledisloe Cup was in 2002 and since then New Zealand have clinched the trophy 19 consecutive years.
