PORT Adelaide coach Ken Hinkley says the Power's wish to wear its prison-bar jumper in every future Showdown is a cause worth fighting for.

The jumper, made famous in Port Adelaide's glory years in the SANFL, will return in next week's Showdown against the Crows but there are no guarantees in place for future seasons.

The issue has resulted in a spiteful back and forth this week between Power president David Koch and his Collingwood counterpart Eddie McGuire, who threatened legal action because of his own club's black and white colours.

The rivals had an agreement in place that Port Adelaide could don the jumper each Heritage round but that theme is no longer part of the AFL fixture.

Koch and co. are now keen for that arrangement to cross over to Showdowns.

"It's incredibly significant for our footy club, and at Port Adelaide it's something that we really believe in," Hinkley told ABC radio of the prison-bar strip.

"It's where we were founded. We're one of the unusual clubs in the AFL today – we come from this suburban team, this small suburb in Adelaide, Port Adelaide.

"We're known with the prison-bar jumper, so to wear that in a Showdown in Adelaide against the arch-rival is something we're really desperate to keep going, and something we think we should be able to keep going.

"I don't think you'll find too many Port people backing away from the fact they'd love to wear the prison-bar jumper against the Crows every year."

Hinkley preferred to stay out of the politics between Koch, McGuire and the AFL but warned the Power would not relent on the issue. 

"What I do know is Port Adelaide people, when they get strong on certain things, they like to make sure they win their fights as best they possibly can," he said.

"This is a fight, if you're picking one, we think this is one worth sticking up for and going hard for.

"Look, it's easy for me, because I'm at Port Adelaide, but I don't see any issue that a state game against the Crows in our state should cause any problems at all for us to wear a traditional jumper we've been known for.

"Everyone that barracks for Adelaide hates that jumper and we love the fact they hate that jumper, and we want to play them in that jumper and we want to get after them in that jumper."

Port faces the Crows at Adelaide Oval on Saturday night and will remain in South Australia until the following Friday, two days before taking on Fremantle at Gold Coast's Metricon Stadium. 

That will limit the time the Power spends in the Gold Coast quarantine hub, and Hinkley compared the expected duration to recent seasons when his team played a game in China.

"We've typically gone to China about this time of year for the last two or three years, and we've spent a week or 10 days away (on those occasions)," he said.

"We're actually going to be gone for about two weeks (in Queensland) at this stage, and it that's the case we have done that pretty well over the last few years and we've been successful at doing that.

"We think we're as well prepared to go and do it as any team, perhaps, in the competition but we're about to find out."
