Australia flanker Sean McMahon is set to move to Japan after confirming he is "done with the Rebels".
The Wallabies back-rower has opted to take up the opportunity of a two-year spell overseas and will miss the 2019 Rugby World Cup.
McMahon has made 15 appearances for his country, but is relishing a new challenge with an unnamed Japanese club as his Melbourne Rebels contract comes to an end.
"We're done with the Rebels at the end of the season and basically all I can say now is that I won't be playing in Australia next year," McMahon said.
"I'll be gone for two years. It was a very big call I've made.
"There was a few factors that came into it - a few personal ones and a few other issues I don't really want to go into.
"It was a big decision for my career and my personal life as well. I'm pretty happy with the decision and so is my wife. We're looking forward to experiencing something new."
McMahon, 23, has not ruled out resuming his international career down the line.
He added: "Maybe down the track I might change my mind but it was great to have the opportunity to play in a World Cup.
"Having to pass that up was definitely a hard factor in the decision. I'm going to take it one step at a time."
