It was a selection which took a while to sink in for the year 12 student from St Francis College.

"I couldn't comprehend it to begin with," she said.

"Dad pulled me out of school when the squad was announced and told me. I couldn't get it through my head."

It continues what has been an outstanding season so far for the youngster who was a key component of the successful Riverina Bulls side which took out the first ever Country Rugby League Championship.

From there Tess was then selected as a member of the NSW women's country team who finished second at the National Championships early this month.

Tess said it was a great experience to be playing alongside Jillaroos Isabelle Kelly, Kezie Apps, Bec Young, Ruan Sims, Hannah Southwell, Keeley Davis and Vanessa Foliaki.

"It was just great to be around those girls," she said.

"The teams all stayed together, so I was having breakfast and walking around with some of the girls who I had watched on TV. It was a pretty surreal experience."

Tess has been putting in plenty of hard work ahead of the clash with Queensland in just over two weeks times with two trips up to Sydney for training runs before the squad goes into camp on Tuesday, June 18.

The squad has been predominantly chosen from the NSWRL's Harvey Norman Tarsha Gale Cup which showcases some of the rising stars in women's Rugby League.

In fact of the 25-player squad that has been selected for the Women's State of Origin curtain-raiser, Tess is the only player not to be playing in the Sydney based competition.

Tess is now focusing on putting the finishing touches on her game.

"Just have to work on my positioning and getting my head around some new ideas from the training sessions," she said.

"I'm just extremely excited to get out there."
