Matthew Primus has put all careers on notice at Port Adelaide in a hardline approach to his audition for the AFL club's top job.

Caretaker coach Primus on Monday told Power players their futures would be decided in a seven-week stint he hopes leads to the full-time coaching gig next season.

"Everyone is on notice - the coaching staff, the playing staff and the medical staff, that is a pretty exciting thing," Primus said.

The popular former Port captain has replaced Mark Williams, who quit as coach after last Friday night's loss to Collingwood, the Power's eighth defeat in a row.

The ex-ruckman, an assistant of Williams since late 2005, said he would offer younger players greater chances for the rest of the season

"Definitely (for) the future of our club for the next few years, we want to have a look at some of those players," he said.

"We need to find some wins, the club has lost eight in a row so that is unacceptable.

"We are going to continue to give opportunities to our younger players ... and there will be some calls made on what is going to happen with the future of our list in the seven weeks also."

The youth edict spells trouble for 30-year-old duo Chad Cornes and Josh Carr.

"Those kinds of players I will be talking to in the next few days and we'll be discussing where they're at and where I think they're at," Primus said.

"We will make some decisions on those players shortly ... there will be some decisions made because the list has to go forward.

"We need to get games into our younger players and there are some players waiting there, and they won't be held back by players who aren't going to be here next year."

Primus said he would tinker with Port's plans and preparations but conceded seven weeks wasn't long enough to leave a huge imprint.

"You can't change a huge amount of things in seven weeks but certain things will play out," he said.

The 35-year-old said being appointed caretaker coach was "a stepping stone towards being a senior coach in the future".

"It's just too good an opportunity to knock back," Primus said on Monday.

"Whatever is going to happen in the future will happen, but obviously I can show what I'm about.

"Maybe it can go against you too, but you never know if you don't have a crack at it."

The Power travel to Darwin to meet the Western Bulldogs on Saturday night.
