Maroons Coach Kevin Walters made the announcement on Monday, December 17th.
Martin (25), who grew up in Queensland, has been a strong performer for the Kumuls, especially during the 2017 World Cup.
This season he achieved his goal of playing in the NRL, with a memorable debut against the Brisbane Broncos in Round Nine, where he scored a try with his very first touch of the ball.
Macdonald debuted with the Roosters as a 20-year-old in 2014 and has emerged as one of competition’s top wingers during his stints with the Titans and Dragons.
He secured a release from the Dragons to sign a long-term deal with the Cowboys in order to be closer to family.
The 24-year-old has also made nine appearances for PNG since debuting at the 2013 World Cup and appeared for the NRL All Stars in 2016.
Emerging Queensland Origin squad: Joe Ofahengaue, Christian Welch, David Fifita, Jaydn Su’A, Rhyse Martin, Ash Taylor, Brodie Croft, Jake Clifford, Corey Norman, AJ Brimson, Phillip Sami, Tautau Moga, Nene Macdonald, Kyle Feldt, Brenko Lee.
