Yet to represent NSW, Trbojevic's call-up caps a stunning week for the 22-year-old who just signed a multi-million dollar four-year extension with the Sea Eagles.

The rookie Kangaroo will likely see game time in Mal Meniga’s side throughout the tournament.

He flies to Perth today before jetting to the UK with the Four Nations squad.   

“Jake will give us size and intimidation,” Meninga said.

“It is always disappointing to lose a player of Josh’s calibre but this will be a wonderful opportunity for Jake and I’m excited to see what he can do in the green and gold jersey.”

Trbojevic has played just two seasons in the NRL, and, along with brother Tom, is considered a future staple of the NSW team.
