CLIFTON sisters Sarah and Eliza Flynn will put sibling rivalry to the test when they face off against each other in a trial match tomorrow ahead of the Australian Country Championships.

Sarah Flynn will be joined by Wheatvale all-rounder Carly Cooper in the Queensland Country Women's Open side to take on sister Eliza Flynn n the Queensland U18 Girls team for a trial match before the start of the tournament.

The match will be played in Brisbane tomorrow.

Cooper said she was more familiar with her upcoming opponent than her new team-mate.

"I have played with Sarah a few times in Darling Downs teams," she said.

"I played with Eliza a lot more when we were both in the U18 side together, I'm looking forward to hitting her around the park a bit.

"Both of the girls have had a lot of time out with injury and playing for the South West Thunder in football."

Copper said she is looking forward to playing the T20 format in the country tournament this week.

"I've really enjoyed watching the Women in the Big Bash League," she said.

"It's great to showcase the sport and get it out there.

"It is a shorter game which is probably more entertaining for spectators."

Cooper and Sarah Flynn will fly out on Wednesday to Mt Gambier to take part in the week-long competition which features teams from across Australia and the Pacific Islands.

Copper said the Queensland side would be ready for the test.

"Most of the team is around the age of 20 but we have a few more experienced players who will help guide us through," she said.

"It will be good to have some experience to guide us along, and to share their experiences with the younger players."

Western Australia will be the hot team to beat but the combination of players from Samoa, Japan and the PNG in the East Asia Pacific side will draw plenty of attention.

"It will be interesting to see how they play," Copper said.

"I've never seen them before so it will be exciting to see what they bring."

Cooper turns 19 in a couple of weeks and has risen through the ranks of junior cricket.

"This will be my first year in the open team," she said.

"I started off in U12's and played right through to U18's when I finished up my youth cricket."

Eliza Flynn will also travelling south as part of the Queensland U18 Girls team who will be playing in the last of the Cricket Australia U18 Girls Championships in Canberra from January 13-19.

The Australian Country Championships begins Thursday.
