On 11 March 2012, the day after St. George Illawarra player Beau Scott had signed with the Newcastle Knights, it was reported by the media that ex Dragons coach Wayne Bennett was also attempting to poach King to Newcastle.[36] As Wayne Bennett got off the Newcastle team bus at Shark Park before the Newcastle side were due to play Cronulla, an irate Saints fan let him know what she thought of his poaching of Beau Scott and speculation that rookie hooker Cameron King may also be Newcastle-bound.
"Don't you take Cameron King off us," the woman screamed as she poked her finger in Bennett's face. "You've taken Beau Scott and Darius Boyd and all those others, but don't you take Cameron King."[37]
On 12 April 2012, it was confirmed that King had re-signed with the St. George club for a further two years which would have seen him stay at the club until at least the end of the 2014 season.[38]

"I'm really excited to have re-signed with the Dragons. We are a very proud club, I really enjoy being here and they have been great to me. We have a lot of young talented guys coming through the ranks and a great group of established senior players. I believe the club has a big future and I want to be a part of it."[40]
On 25 September 2013, King signed with the North Queensland Cowboys. At the time King Said "The Cowboys have given me the chance to play some more regular NRL and an additional year so I am looking forward to this and am thankful to the Dragons to allow me the chance to take up this opportunity."[45][46][47]

King started his career for the North Queensland side by playing in their reserve grade feeder team Northern Pride RLFC in the Queensland Cup.
In the round 10 match against the Sydney Roosters, while attempting to make a tackle, King ruptured the anterior cruciate ligament (ACL) in his left-knee four-minutes from full-time. "King's been a turning point for us," said teammate Brent Tate, "so it's really disappointing."[48][49]

In an interview with the Daily Telegraph in December, King thanked his friendship to former NRL player Kyle Stanley for his career and the help he was given during every injury set-back. "He was just so inspirational,’’ King said. "We have been best mates since we were 15 and I have never met a tougher man. What I was going through was nothing compared to what he had copped and he really put it into perspective.'’ "He will be on the field with me every game I ever play,’’ King said. "I have made a promise to write his name on my wrist every time I take the field.'’[54]
2017

On 29 October 2019, it was revealed that King had been released by Featherstone. King spoke to the media saying "Things are probably taking a little longer than I'd hoped, But I do have options back in the UK and in Australia. It's good to get back home and be talking to people and figure out what I want to do. I've been around friends and family and had a mental break from footy, but I've been assessing the options for next year, whether that be the Championship again, stepping up to Super League or coming back to Australia".[66]
In February 2020, King was taken from the field during Cronulla's trial game against Canterbury-Bankstown with a suspected knee injury. It was later revealed that King had suffered a season ending ACL injury. King posted on Twitter saying "It's still sinking in that my season is over. It's been hard to accept what's happened and I'd be lying if I said I'm ok. I'm taking things 1 day at a time and determined to not let this defeat me physically or mentally. Thank you all for the support".[68]
On 15 October 2020, King announced his retirement from the NRL.[69]
