Cameron Smith says the Rugby League World Cup final against England may offer some of Australia's modern greats an opportunity to bow out of the international game on a high.
The holders and favourites meet Wayne Bennett's team at Suncorp Stadium in Brisbane on Saturday, when Smith, Cooper Cronk and Billy Slater could all be making their last appearances for the Kangaroos.
And while the prospect of retirement has not been openly discussed, Melbourne Storm, Queensland Maroons and Australia captain Smith knows the decorated trio are unlikely to grace this stage again together.
"Billy hasn't indicated to myself or the team that it could be his last game, but I think there's probably a question mark over a few of the guys in the side at the moment," he said.
"We're all getting a little bit older now. For ourselves and what we've tried to build over the last two seasons, we want to make sure we go out playing our best football.
"To win a World Cup on home soil would be top of the tree as far as my international career is concerned, but it's going to take a pretty big effort."
