The Australian Rugby Union (ARU) have been in contact with Victoria, Queensland, South Australia and Western Australia about the possibility of hosting its headline act, but overseas venues such as Twickenham are also considered a serious option.
"Argentina are playing their home game against us at Twickenham in the Rugby Championship this year, so there is a precedent there," ARU general manager Rob Clarke told News Corp Australia.
"Even a city like New York, where there is a strong Australian and New Zealand expat presence, have expressed interest in getting more international rugby content. It is a consideration for us, certainly."
Such a move would only fall in the years which Australia has the right to host two matches, and given 2019 is a World Cup year, it leaves 2020 as the only real viable option.
It would mark the first time a Bledisloe Cup match has been played outside of New Zealand or Australia in a three-match series.
Hong Kong has twice hosted matches and Tokyo once; however, both were money-making fourth games added on to the end of the annual series.
