Jewitt and his family are moving to Australia where the 29-year-old forward has signed a one-year contract with Townsville Blackhawks, the feeder club for North Queensland Cowboys. Jewitt joined the Tigers in 2014 from French side Limoux after making over 100 appearances for Salford City Reds in a six-year spell.
He started his career with Wigan Warriors, for whom he made his debut in 2005.
Jewitt said: “Bec and I have always wanted to live in Australia. We’ve dreamt of doing it all our lives and eventually we want to emigrate over there.
“It will be really tough for me to leave Cas. I’ve dreaded this bit, I reckon if I was at any other club then I would just be doing my job, but this club is special, I love it here, and it’s not just me, when your kids are always talking about it and how much they love it, then yeah it’s going to be tough to leave here.”
Jewitt says he cannot thank the club enough for all the support he received following the premature birth of his twin boys last year and he has now set his sights on going out with a bang.
He added: “I want to leave here on a high. This is a special club and a special team.
“The dream for me now is to leave knowing that I’ve helped bring a trophy back to this club, because this club and these fans deserve that.”
