UPDATE @ 12.30PM - Josh Mansour joins Reagan Campbell-Gillard in the Kangaroos squad!

Panthers prop Reagan Campbell-Gillard has been added to the Australian squad to contest the 2017 Rugby League World Cup.

Campbell-Gillard, who on Wednesday night was awarded the 2017 Merv Cartwright Medal, received the surprise news from Kangaroos coach Mal Meninga on Thursday morning.

His call-up comes following the decision of Andrew Fifita to withdraw from the Kangaroos squad in order to play for Tonga.

"Andrew called me and said he was passionate about playing for Tonga and I respect and support that decision," Meninga said.

"It is obviously a significant boost for Tonga as well as the World Cup – and international Rugby League in general.

"At the same time it is also a great opportunity for someone like Reagan, who has been outstanding for the Panthers.

"I'm extremely excited about seeing Reagan in a Kangaroos jersey."
