Cosh, 19, played three games for NSW Country running on as five eighth.
The tournament was conducted during the three days of the long weekend with teams from the Northern Territory, NSW Country, QLD Country, Qld Invitation XV, South Australia and Victoria participating.
The tournament was played at the Palm Beach and Currumbin Rugby Club grounds.
Cosh said his first game against the QLD Invitational XV was a tough match, but the NSW attack was too good, taking down the invitational side 37-10.
“It was tough playing in wet conditions but we handled the ball well and came out on top,” Cosh said.
He went on to say last month’s match against the ACT really opened the eyes of the players, but as for the standard of rugby, he said they needed to pick up their game to be successful at the next step in the representative level.
His second match against Victoria was the toughest of the day with NSW Country failing to secure a victory losing 31-12.
“They were a strong team and we couldn’t keep up with them. “They ended up running away with a few quick tries in the second half.”
Their third and final match against the Northern Territory was a close one.
Cosh scored a 40-metre runaway try to secure the 12-8 victory against the Territory.
“I took an offload off the inside centre and made a clean break to the try line,” Cosh said.
The tournament will wrap-up representative football for Cosh this season.
He will now be focusing his attention on making this year’s semi-finals for the Weebolla Bulls.
