The duo is rooming together in the Blues' camp in the lead-up to Origin III after both made the 18-man squad to face Queensland, with the ledger at 1-all after the Maroons claimed the first game in Brisbane and the Blues hit back in game two in Perth two weeks ago.

Maloney has been named at five-eighth for the decider with Wighton in the centres. The pair is expected to defend together on the Blues' left edge.

A Bloomfield junior, Wighton also spent time with CYMS while Maloney is a former St Joseph's Sheahan junior.

Both have held their starting spots after a huge 38-6 win in Origin II and will head into the decider looking to secure the Blues' back-to-back series wins for the first time since 2005.

Both the Orange products' flexibility might be needed too, with Panthers' Nathan Cleary still under an injury cloud with a bung ankle suffered in the Perth clash, and while NSW coach Brad Fittler said he'd been given "as much time as he needs", either Orange junior could slot into that role should Cleary not pull up.

"The fact is we've got Wade Graham and Jack Wighton who can play five-eighth," Fittler said.

"We're pretty confident [Cleary] is going to play, but Wade Graham did a fantastic job in Perth and also Jack Wighton, so we feel very safe with what we've got in camp."

Tariq Sims was also named despite being under a suspension cloud, with the Dragons forward facing the tribunal for a potential three-match ban after deadline on Tuesday night, replacing enforcer David Klemmer - who missed Origin II with a broken wrist and was controversially overlooked.

Origin III is on July 10 from 8.10pm at ANZ Stadium in Sydney.
