Winger Matt Ikuvalu will follow coach Craig Fitzgibbon from Bondi to Cronulla after being granted a release from the final year of his Sydney Roosters NRL contract.
The 27-year-old Ikuvalu joins the Sharks on a two-year contract as the club announced the retention of veteran prop Aiden Tolman, along with the signings of Olympic rugby sevens player Lachlan Miller and hooker Jayden Berrell.
Ikuvalu was picked up by the Roosters while working as a shoe salesman and went on to score 25 tries in 38 NRL games for the club, including a five-try haul against North Queensland last year.
"It has been a pleasure to coach Matt and to watch him progress from a fill in training role to a key contributor in our NRL squad," Roosters coach Trent Robinson said.
Ikuvalu will compete with Sione Katoa and Ronaldo Mulitalo for a spot on the wing in Fitzgibbon's maiden year in charge of a first-grade side.
The former Roosters assistant has been busy in the transfer market having already added Dragons captain Cameron McInnes and Melbourne duo Nicho Hynes and Dale Finucane to the revamped Sharks squad for 2022.
Joining them is 27-year-old Miller, who was part of Australia's sevens team in Tokyo, and had been linked with Cronulla more than month ago.
Having the ability to cover the spine or backline, the Sharks believe Miller turned down other opportunities in league and union to sign a two-year deal.
Berrell, meanwhile, will provide back-up at hooker to Blayke Brailey and McInnes after his exploits in Wynnum-Manly's journey to the Queensland Cup grand final were brought to Cronulla's attention by Mat Rogers.
Rounding out the Sharks' flurry of signings is Tolman, who has opted to prolong his career on a one-year contract.
The 32-year-old joined from Canterbury before the start of last season and has acted as a calming influence on a young squad with the talent to challenge for the NRL's top four in 2022.
"I enjoyed my first year at the club and I'm really happy to be returning for a second," Tolman, who is four games shy of joining the NRL's 300 club, said.
"We've got some quality players joining us and a new coach in Craig who I'm looking forward to working with."
Elsewhere, South Sydney have signed 22-year-old winger Isaiah Tass, who had previously been on the books of Brisbane and Canterbury, on a one-year deal.
