Weilandt will represent the NSW Kangaroos and is one of 11 Riverina players to be selected across three state sides.

"I've never been to a national carnival at any level, so it's pretty exciting," Weilandt said.

"The good thing about cricket is that even at my age, you still have the ability to play at higher levels."

An Australian side will then be selected for the World Cup in South Africa in March next year.

While Weilandt admits competing at the World Cup would be a dream, he's just taking it one step at a time.

"Making the national championships was the main goal," Weilandt said.

"If I happen to have a great tournament and get picked then that would be great, but I'm not counting on it.

"It's quite a good standard with a lot of good players."

The championships kick off on Sunday and run until Thursday, November 21.
