Red Devils director of rugby and operations Ian Blease said: “Sita wanted to come to Salford to show what a quality player he really is and he is a fantastic acquisition for the club as we look to challenge at the top of Super League again.
“He adds size, strength, athleticism and versatility to the pack and I look forward to seeing him rip it up in a Salford shirt.”
Akauola becomes the sixth recruit for Salford, who have yet to appoint a new coach for 2022, following the signings of Brodie Croft, Shane Wright, Amir Bourouh, Ryan Brierley and King Vuniyayawa.
“I’m really looking forward to playing for Salford,” he said. “It’s a club with passion and ambition.
“It’ll be great to be playing in front of that Salford faithful, who I know are a massive part of Salford Red Devils.”
