The 24-year-old forward has made 17 appearances for the Sharks since making his first team debut in 2019.
“The club is highly regarded over here in Australia and I can’t wait to get over now and get to work.
“The squad is really well balanced and I know I’ll fit into that. I want to make an impact and have a real positive effect on this team on and off the field. I’m looking to progress my game as well as the club – which hasn’t been where it wants to be in terms of the Grand Final. That’s where I want to be and winning trophies.
“I love a challenge and I don’t shy away from one. I don’t have an issue with getting out of my comfort zone and coming to the other side of the world to test myself. Warrington have provided me that opportunity now to show what I can do over in Super League and I can’t wait.”
Warrington coach delighted to sign Billy Magoulias
Warrington coach Daryl Powell said: “It’s great to have Billy on board for 2022.
“He has the right qualities as a ball playing forward to enhance our options in the pack for next season and implement the brand of rugby we’re going to strive to achieve.
“From my conversations with him I know he’s excited for the challenge of moving to the UK and showcasing his abilities in Super League.
“I’m looking forward to working with him and continuing to develop his game.”
Magoulias is Warrington sixth new signing for 2022. The club have already announced the captures of Peter Mata’utia, Oliver Holmes, Joe Bullock, James Harrison and Greg Minikin.
