COOPER Cronk won't be switching to rugby union with the struggling Waratahs in 2018.
The Kangaroos halfback will leave NRL club Melbourne at season's end to join his Sydney-based fiancee Tara Rushton, but hasn't announced his playing future.
Wallabies coach Michael Cheika said earlier in the week that Cronk would be a rugby success and the Waratahs should sign him.
Code-hopper Karmichael Hunt also backed a Cronk move to rugby.
But Cronk denied he would play for the Waratahs next year.
"That won't be happening," he said.
"I did play a bit of rugby at school and thoroughly enjoyed it and I watch rugby and played with some of the current Wallabies.
"But I love rugby league. It has given me everything I have in my life.
"I am an avid supporter of the game."
Cronk, 33, said he was physically and mentally able to play on.
"My intention is to make a decision on if I play again next year not where I am going to play," he said.
"I will have an answer for you at some stage.
"I won't be dictated by the market.
"I need to make a smart decision and they don't happen overnight."
