Kangaroos coach Mal Meninga is interested in a possible history-making clash between the Kangaroos and All Blacks in 2019, but is sceptical it will ever happen.
Organisers claim they have already reached out to the New Zealand Rugby Union, while Australian Rugby League Commission chairman John Grant has also been approached.
News Corp reported the game, mooted for Japan following the 2019 Rugby World Cup, would attract $50 million in revenue from commercial and broadcast deals.
Almost half of the profits would be paid to each team and while Meninga admitted being intrigued by the idea, he described the possibility as a "pipe dream".
"It's interesting isn't it. It'd be a promoter's dream I would guess. We haven't given it much thought, I just saw it in the papers overnight and this morning," he said.
