"It's been a tough couple of years since my shoulder surgery and I haven't quite got back to the form I was in. That's been frustrating. I just want that crack. I am excited to be going over there and starting again.''
Blues coach Pat Lam didn't seem to have faith in King, and plumped for No 8 Chris Lowrey to play in the second row when faced with a locking crisis towards the end of the last campaign. King's agent approached the Blues about playing for them next season but was told they had plenty of tall timber with the likes of Ali Williams, Anthony Boric and Liaki Moli on the books.
King is both athletic and abrasive - the 2m, 111kg second-rower was once described as Isaac Ross but with grunt - and he hopes his agility will provide the Rebels with a point of difference . He replaces former All Blacks and Chiefs lock Kevin O'Neill, who played one season for the Rebels.
"When you get in a new environment, no one will know who I am, so I see it as a chance to impress,'' King said. "I'm looking forward to that. I have always been a bit different in terms of my agility as a lock.
"In Australia they are quite big boys and I play a little differently to them so I'm hoping what they see is new and something they like.''
The Rebels finished bottom of the Australian conference, with three wins in their 18 games.
