Both products of the Mackay region, Dunn and Cotter have come through the Cowboys Elite Pathways Program before progressing on to the NYC and finally the NRL.
Dunn has played 11 NRL games since making his debut in Round 13 last season.
The 22-year-old has emerged as a skillful back-rower for the Cowboys after playing the majority of his junior football in the halves.
Dunn was a regular in Paul Green’s side at the start of 2019, before a shoulder injury ended his season in Round 13.
Cotter’s journey to first grade has been nothing short of remarkable.
The 20-year-old dummy half missed the 2016, 2017 and 2018 seasons through consecutive ACL injuries.
He made his long-awaited return from injury in a Cowboys’ trial against the Titans in February and was called up for his NRL debut in Round 13 against Manly.
“We’re delighted to re-sign two young players from our region who have come through our pathways program and have shown promise in their opportunities in the NRL,’ Cowboys Director of Football Peter Parr said.
“We believe both players have big futures and we see no reason why these contracts aren’t the first of many at our club.”
