Lachlan Stein is one of seven uncapped players named in the Scottishr World Cup squad.
Forward James Bell of NZ Warriors, Sydney Roosters’ Jarred Anderson, and Penrith Panthers’ centre or wing Lachlan Stein are included for the first time, as are Bradford Bulls’ youngster Brandan Wilkinson and Shane Toal - who scored 28 tries for Barrow in their promotion campaign - both of whom came through the Scotland Under-19 pathway.
“It’s just reward for those players,” said McCormack.
The Bravehearts fly to Brisbane on Sunday, play New South Wales Country on 20 October before heading to Cairns for their opening Pool B game against star-studded Tonga on 29 October.
