London and even New York are being considered as venues for a Bledisloe Cup game in 2020.
The Australian Rugby Union is considering the move during the $780m renovation of Sydney's ANZ Stadium, according to the Daily Telegraph.
"We are a global game so global opportunities will present themselves," ARU general manager Rob Clarke said.
"Argentina are playing their home game against us at Twickenham in the Rugby Championship this year, so there is a precedent there.
"...we have to balance that against rewarding our fans here in Australia and giving them top-class rugby content. So we wouldn't make that decision lightly, but it is certainly part of the framework."
