Queensland prop Fletcher Dyson wasn't lying when he labelled his meteoric rise to the Wallabies as unexpected.

Dyson was chosen to meet Argentina at Ballymore on Saturday week in the first Test of the Wallabies' international season. If Dyson is still on board for the last Test of the year, he'll have a problem.

The tighthead prop has set his wedding day for November 18 - the same day the Wallabies will play England at Twickenham. But Dyson isn't worrying yet, knowing plenty could happen between now and November.

Plenty has already happened to the 27-year-old since he arrived in Brisbane six months ago with modest goals. He just wanted to win a bench spot for the Reds and to let people know Fletcher was his christian name, not his surname.

Dyson moved north following an invitation from Reds coach John Connolly after he struggled for exposure with New South Wales. He quickly sprung into the Reds starting team and cashed in on the retirement of Andrew Blades and injury to Patricio Noriega to earn his first Test berth.

He was named in the Wallaby squad alongside Chris Latham and Sam Cordingley - former southern players who also found greener pastures in Queensland.

"It's fantastic just to think I'm going to pull on the jersey of the World Cup-winning Wallabies," Dyson said. "I know there's going to be a lot of pressure but I've just been pinching myself so far."

It's not bad for a prop who couldn't crack Northern Suburbs' first grade team in Sydney just a few years ago during the lowest point in his widely-travelled career. Raised in Victoria, Dyson spent his high school years in Brisbane and eventually played representative rugby for NSW Country.

He then made the Australian under-19 team and the NSW under-21s but he then spent some years in the wilderness before he moved to Randwick in 1998.

"They say a change is as good as a holiday and I really just went there to have fun and things started working out," Dyson said. "I toured with the Waratahs later that year and then had a contract (for 1999)."

But Dyson only received seven minutes' playing time in the 1999 Super 12 season and he was still disappointed NSW did not do more to keep him when the Reds showed interest.

He took special delight in beating the Waratahs last Saturday night, admitting "it doesn't get any better than that".

It did on Wednesday when he received the Wallaby call-up but Dyson knows he has a job on his hands anchoring the Australian scrum. Dyson has been playing in the specialist tighthead position since he bluffed his way into the spot when NSW Country was caught short almost 10 years ago.

"I've been bluffing ever since I suppose but, if you make a mistake at tighthead, you can be transported from one side of the field to the other which is very humiliating," Dyson said. "And this is going to be a real challenge. Argentina pride themselves on their forwards and it's not going to be easy."
