THE 'GO home' factor has been costing clubs interstate players for years.

With 26 of Port Adelaide's 44 senior-listed players from outside South Australia, it had the potential to decimate the Power's playing list.

But newly re-signed 19-year-old Aaron Young believes the high percentage of outside talent at the Power can work in the club's favour, not against it.

The interstaters have formed a close bond, he said, especially under the trying circumstances Port's players have had to endure over the past few seasons.

All four of the club's re-signings it announced on Friday, Jasper Pittard, Cameron O'Shea, Jarrad Redden and Young are from interstate.

The quartet committed to the Power until the end of 2014, following in the footsteps of fellow out-of-towners Robbie Gray, Jackson Trengove and Alipate Carlile who all penned new deals at Alberton within the past 12 months.

Young, drafted to the Power from the Melbourne-based Eastern Ranges at the 2010 NAB AFL Draft, said Port's interstate contingent wanted to stay together rather than split up and go home.

"I think all of us are a pretty close-knit group and sticking together is something we want to do and especially given the tough time the club's been going through," he said.

"Adelaide's a great place to live, there's more sun than Melbourne and less traffic, but the main part is sticking together … and getting games together with the young group so that in the next few years we can be a really competitive side."

Fellow Eastern Ranges draftee O'Shea agreed.

"We are pretty tight off the field and spend a lot of time with each other, so it's definitely a big factor in all of us re-signing," the 20-year-old said.

Interim coach Garry Hocking wasn't afraid to remind everyone exactly who was a local and who wasn't at the Power's training on Tuesday.

Young said the South Australian players were pitted against a "rest of the world" team in a range of football-orientated mini games.

Neither side came out on top, with the final score a convenient 1-1.

"There was a bouncing ping pong balls into cups and blindfolds going through obstacle courses and things like that and then a swim relay race," Young said.

"It was just good to break it up and do something a little bit different in the last week and the boys got a lot out of it, there was some reaction time stuff in there, so it's all football-related and it keeps you on your toes."
