Talanoa, 25, has penned a one-year contract at the Black and Whites with an option for 2015 and will link up with head coach Lee Radford’s squad subject to being granted a work permit.
Equally at home on the wing, at full back or in the centres, Talanoa ran in 40 tries during 95 appearances for the Rabbitohs between 2006 and 2012 and was tipped for a bright future in the game before suffering a life-threatening bout of pneumonia.
Choosing to spend time recovering with family rather than see out his contract with the NRL club, the 25-year-old is now back to full fitness and eager to make the most of his return to rugby league.
He told www.hullfc.com, “Hull FC have given me an opportunity to play for their club and I’m really excited for it. I can’t wait to get over there and represent the Black and Whites.
“For me it’s about getting back into playing rugby league. League is where my heart is and that’s what I enjoy doing but first of all, I’ve got to make the team and that’s a battle I’m really looking forward to.
“My first priority is to get a starting spot in the side and then to give the club 100 per cent every time I put the jersey on.”
Talanoa follows in the footsteps of rugby union international Tom Biggs, Tonga’s World Cup forward Mickey Paea, ex-New Zealand prop Feka Paleaasina and Wigan forward Chris Tuson in moving to the KC Stadium for 2014.
