CHRIS Ostwald is on the verge of his lifelong dream - set to wear the Maroons' jersey for the first time in front of a parochial Suncorp Stadium crowd.

The former Kingaroy Red Ants junior will run out for his state tomorrow night as part of the Queensland 18s squad set to face New South Wales in the curtain-raiser before Origin II.

Ostwald will come off the bench as a reserve hooker when he makes his debut for Queensland.

Wearing the jersey is something the 18-year-old, who grew up in Gayndah, has always aspired to.

"It's been my dream growing up like a lot of junior players in Queensland, and playing in front of the home crowd is even better," he said.

"Just being in camp has been an unreal experience and it's just going to get better on Wednesday night."

Otswald has been training with the Maroons senior squad, which gave him the chance to meet a fellow Red Ants junior.

"I had a chat with Chris McQueen and we just talked about Kingaroy, and he thinks it's just the biggest experience you can have," he said.

"He was so supportive and said to show them what we can do and to take your chance, and I just hope I can do that."

Ostwald said nerves had been playing on his mind as he prepared for the biggest game of his life.

"When I first got the phone call I had at training last Tuesday (my nerves) were pretty high, but throughout the camp they settled down but now they're getting pretty high again as we get closer to the game," he said.

Ostwald moved to Brisbane late last year to pursue his rugby league career after attending Kingaroy State High School for the past two years.

The former Wide Bay rep has been part of the Brisbane Broncos U20s Holden Cup training squad, as well as playing for the North's Devils in the FOGS junior competition.
