St George Illawarra recruit Korbin Sims has expressed his disappointment with not being offered a new contract by the Broncos due to their salary cap squeeze.

The 26-year old will join his brother, Tariq, at the Dragons, and return to his native area of Gerringong on NSW's south coast, but has revealed it was his preference to remain in Brisbane.

"My first priority was to stay in Brisbane, but obviously they couldn't offer me a contract which was disappointing," Sims told the Sydney Morning Herald.

"There's no hard feelings there and with the Dragons it was pretty simple, I wanted to be playing football with Tariq again and that made it a lot easier decision.

"It's a business at the end of the day and the Broncos couldn't offer me a deal. I took that with a handshake and moved on. I'm still very excited to move down to the Dragons. It wasn't a hard decision."

Sims said he had always wished to reunite with his brother some day, adding that he is hoping to take his game to the next level and earn his first Origin jersey.

"Being able to play footy with him again was always in the back of my mind and whether it was going to be here, there or anywhere else," Sims said.

"The forward pack with the Origin standard they've got at the moment was always going to be a juicy incentive, and to play under Paul McGregor with Tariq and the standard they've got down there. There was a couple of different things I liked about the move.

"If I'm playing around good players, which I am at the moment, my goal is to go to the next level. I'm definitely still striving for that jersey and I'm desperate to play Origin. I've just got to keep working on my game.

"My priority will be to play good footy with the Dragons and see what happens from there."

Despite the switch, Sims maintains that he is still as determined as ever to finish his career with Brisbane as a premiership player.

"We know we've got the crop of lads that can win a comp and we don't want to let it go by another year," Sims said.

"There's a couple of lads that are really driving it and we'd love to send him out with a bang.

"It's been so long between premierships for the club; we're really focused on winning it this year."
