Four Penrith Panthers will line up for three different nations in the 2017 Rugby League World Cup.
Prop Reagan Campbell-Gillard will don the green and gold for Australia, while utility Sione Katoa has been named in the Tonga squad, according to statements from the club.
Outside backs Dean Whare and Dallin Watene-Zelezniak have been named in the Kiwi squad.
Campbell-Gillard took out the 2017 Merv Cartwright Medal at the club on Wednesday, October 5, and received the news from Kangaroos coach Mal Meninga the following morning.
The call-up came after Andrew Fifita withdrew 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."
Tonga head coach Kristian Woolf said Tonga had been drawn in a “very strong group”.
"Tonga needed to pick as strong a squad as possible and with the team we have been able to assemble, we think we have the ability to be very competitive," he said.
