The forward has agreed a two year contract.
Huddersfield Giants Head Coach Rick Stone has added to the signing of Jake Mamo with prop forward and fellow Australian Shannon Wakeman on a two year contract.
The 26-year-old was at the Illawarra Cutters last year gaining selection to the "NSW Intrust team of the Year" as well as helping the Cutters to the League title in 2016.
Stone told www.giantsrl.com: "Obviously the move away by Craig came a bit out of left field and left us searching for an established and experienced out and out front row forward.
"I had already considered Shannon for further down the line for us but when our situation changed then Shannon was my go to guy to come across.
Wakeman added: "I am happy to have a new challenge overseas and in the Super League at Huddersfield. I'll be teaming up again with my front row partner Sebastine Ikahihifo who played last year with us for a while before he moved to the UK so it'll be good to have a familiar face when I get there.
"I'll spend Christmas here in Australia and then as soon as my documentation comes through I'll be straight across and ready to rip in for the Giants. I've wanted a crack full time in the top grade for a long time now and reckon I've served my apprenticeship so the opportunity at Huddersfield is great for me and one that I want to make the most of."
