Cameron Murray says a move to rugby union remains a possibility later in his career, as he prepares to watch teammate Angus Crichton's switch to the Waratahs.
"It would be awesome to travel and soak up the atmosphere of what's being tossed up," Murray told reporters in Brisbane.
"I'll watch closely his (Crichton's) career because he's a good mate and I want to see him do well.
"I always support the leaguies that are making the change. So, that's probably the main reason. But it's always in the back of my mind, and I've always maintained the fact that it would be something I would look at later on in my career."
Murray played for Australia's schoolboys and Newington College's first XV. His South Sydney contract runs through 2028.
Meanwhile, Reece Walsh has prompted speculation with an Instagram post from the Kangaroos' Brisbane camp before Sunday night's Rugby League World Cup final against New Zealand at Suncorp Stadium.
Photographed beneath Queensland Reds and Wallaroos locker logos, and the number 10, Walsh captioned the image "2031," with a salute emoji and Australian flag. Fans interpreted it as a possible rugby union switch for the United States World Cup, perhaps as a fly-half.
Walsh is contracted to the Broncos through 2029 and will be 29 when the tournament begins. Rugby Australia chief executive Phil Waugh has expressed interest in recruiting leading talent; Mark Nawaqanitawase, Joseph-Aukuso Suaalii, Zac Lomax and Crichton have made the code switch.
