But Corey Allan admitted he could so easily still be camping in central Queensland with his mates oblivious of his historic selection.

Allan, 20, had to introduce himself to his high profile teammates when he arrived for PM's XIII training in Brisbane ahead of their clash with PNG in Port Moresby on Saturday.

The try-scoring speedster has been plucked from Queensland Cup side Souths Logan by coach Mal Meninga after graduating from the Brisbane Broncos under 20s.

Allan starts a three-year South Sydney deal in 2019.

"Yeah I have had to introduce myself to a few (players) but it was good to have (ex-Bronco) Ben Hunt here who knew me from last year, now I feel comfortable," said Allan, who was named at fullback.

"I am just going to ask a thousand questions and learn what I can."

After pinching - and introducing - himself at training, Allan admitted it was only dumb luck that ensured he had received the selectors' phone call.

Allan had no phone reception while on a camping trip at the fishing town of Seventeen Seventy and only got the selectors' call when a friend's Hotspot randomly turned on.

He then had to drive six hours to get to Brisbane.

"It was just lucky timing that I picked up the call, it's pretty crazy," Allan said.

"I didn't think it (selection) was real at first.

"I thought they would just let me train with them and learn off the big boys.

"But when I found out I was actually playing I was over the moon and rang my dad straight away."

The PM's XIII fly out to Port Moresby on Thursday.
