Shane Flanagan aims to revamp the Dragons' roster for NRL Finals contention after recent departures.
Since Shane Flanagan took over as head coach, the Dragons have made several changes to their roster as they attempt to return to the NRL Finals, having spent the past few seasons near the bottom of the ladder.
With Jack de Belin and Sione Finau departing at the end of the season to the Eels and Raiders, the club are hoping to free up more spots on their Top 30 roster.
"I'm really excited to come and join a new team. I was happy with the way they treated me. Everything was really positive," Ravalawa said.
"I'm looking forward to getting ready to rip in with the boys and experience a new county for the second time. My strengths are my kick returns and scoring some tries.
