AFTER losing to Greater Western Sydney in round 19 last year, Port Adelaide is making sure the embarrassment won't be repeated when the teams meet on Sunday.

That loss cost the coach, Matthew Primus, his job, so, unsurprisingly, Port's new coach Ken Hinkley is making sure his team brings its A-game to Skoda Stadium when it takes on the winless Giants.

Although the Giants have a 68-point average losing margin this year, they showed last week what they were capable of when they stunned ladder leaders Geelong in the opening term.

Hinkley said to treat the Giants like anything other than a top-class side could spell disaster.

"We saw last week what they were able to do first hand when they scored five goals to zip against Geelong in the first 10 minutes of the game," Hinkley said.

"They're a very capable young side that, given some space, they can hurt you.

"Whether it's against GWS or whether it's against Geelong, we need to make sure we display the same sorts of traits and actions that you want to see."

Although the memory of last year's loss is sure to burn in many of the players, Hinkley said it had not been  mentioned.

Before being appointed Port coach, Hinkley was an assistant at Gold Coast for three seasons from 2010-2012.

And he believes his involvement with the Suns offered him valuable insight into the workings of the young Giants.

"I've got great knowledge of a young side at the Suns and I look at what they've been able to do in the back half of last year and what they've been able to do this year," he said.

"If you look at the two sides, almost line them up together – they're very close in what they've been able to do I think.

"What I do know is [the Giants] play risk free, they don't get inhibited by anything because they're a young side willing to take the game on.

"We need to make sure that what we're doing is what keeps us in games and makes us competitive."

While ruckman Jarrad Redden has avoided surgery on his injured shoulder, Hinkley was pessimistic of his chance to face the Giants on Sunday.

Brent Renouf is also unlikely after managing just two handballs in his SANFL hit-out last weekend.

Hinkley said Matthew Lobbe would be the club's sole ruckman.

"I doubt that Redden will be ... available to play and Renouf probably needs another game [in the SANFL]," he said.

"That will almost force our decision a little bit with 'Lobbes' (ruckman Matthew Lobbe); I'm predicting that Lobbes is probably going to play in the ruck and be the sole ruckman."
