The 17-year-old is on the verge of making his under 19s National Championships debut for NSW/ACT after being called up as a late inclusion by head coach Kyle Piper.

An injury to a top-order batsman paved the way for the Orange City star and now, he's preparing for a three-day tilt at Blacktown against NSW Metro, set to kick-off on Wednesday.

This comes not long after Weymouth, along with City teammate Harry McGregor, represented Combined High Schools in the statewide carnival with Weymouth unsurprisingly earning selection into the merit team.

Weymouth touched down at Sydney airport on Monday morning and will join the likes of Western's Tom Coady, Ben Mitchell and Brock Larance at camp.

Although it's a significant call-up, Weymouth says his nerves are easing as the time passes.

"I was nervous but now I feel like I'm more excited," he said.

"It will be good to see how I go against those sort players. I'm just here to fill-in so there aren't many expectations on me."

With so much success at the local level, Weymouth doesn't plan on changing anything about his game and looks to slot into the opening role at West Sydney.

While a three-day hit-out at Blacktown is exciting, Weymouth's equally stoked about a looming trip to Brisbane on Monday where the squad will square off against Queensland in another three-day showdown.

Not only is traveling for representative duties, Weymouth will also need to dedicate time to the BOIDC grand final as his Warriors will shoot for back-to-back crowns on Saturday against minor premiers St Pat's Old Boys.
