Newcastle Knights' goalkicking winger or full-back Josh Mantellato has become Hull KR's third new signing for 2015.
The 27-year-old, who represented Italy at the 2013 World Cup, has signed a three-year contract to join fellow outside backs Ken Sio (Parramatta) and Darrell Goulding (Wigan) at the Robins next season.
The 6ft 5in Mantellato has made two NRL appearances for the Knights and is on course to top the points-scoring chart in the reserve-grade New South Wales Cup for a third consecutive year.
Hull KR coach Chris Chester said: "Josh comes to us highly recommended from Australia and we are thrilled to have him on board for next season.
"He is a player we targeted six or seven weeks ago and he comes to us as a proven try-scorer and also a fantastic goal-kicker."
Mantellato said: "I've been a bit of a late bloomer and my ambition is to come over there, cement a regular first-grade spot and do my bit for the team.
"I'm not coming over for a holiday, I'm coming to test myself. I've played in England a couple of times with the Italian national side and I love how loud the fans are. It's something I'm looking forward to experiencing every week.
"Hull Kingston Rovers is a passionate club as well so I'm really excited about the move and hopefully what I lack in NRL experience I can make up for in other areas."
