The Power sit fourth in flag betting at $11, behind Fremantle, Geelong and premiership fancies Hawthorn. They face all three (and Greater Western Sydney) in the coming weeks.
Having triumphed on one of the hardest road trips in football last weekend, by defeating West Coast in Perth, Hartlett said the time had come to answer questions about his side's premiership legitimacy.
"Over the next month or four games those questions will be answered," he said.
"To be a football club that gets to the top you need to compete against these teams and you need to beat these teams so the guys are really looking forward to it.
"We’ve gained a lot of confidence over the last 12 months or so and we've still got areas of our game we need to work on – we're well aware of that.
"But what better way to test those areas and those deficiencies than against the great teams of the competition."
The Power will enter the first of its huge tests, Sunday's clash against Geelong at Adelaide Oval, with nearly a full list to choose from after Jay Schulz, Jackson Trengove and Chad Wingard were all cleared of serious injury after Saturday's win over the Eagles.
Even Angus Monfries, who booted seven goals against the Cats in round 20 last year, is shaping as a likely inclusion after training with the main group on Tuesday.
The important forward appeared certain to miss at least a month of football after tearing his hamstring in round three but, having missed just two games, could return to the side on Sunday.
Schulz didn't train on Tuesday as he recovered from a badly cut lip, but Hartlett said he'd be available.
"Schulz is probably the main one – his face is a little bit mangled at the moment," he said.
"He's got a couple of boxes of Panadeine Forte to get him over the line for the next few days so he'll be right and Chad and Jackson are just a bit sore but nothing of any major concern.
"[Monfries] would like to say he's very, very likely. He was pretty determined to come back for this game he obviously played pretty well against them last year…he'll do everything he possibly can to put his hand up."
With the game held on Anzac Day weekend, the player judged to have best displayed Anzac ideals on Sunday will be awarded the Peter Badcoe VC Medal.
Hartlett won the coveted medallion in last year's win over the Eagles, the 10th time the award had been presented.
Port CEO Keith Thomas said the club had a strong connection with Anzac Day and would lobby the AFL to play on it next year.
"We will lobby them again, every year it's the No.1 priority pick is Anzac Day, we see it as being that important," Thomas said.
"We will be going in again this year with a major presentation about its significance and why that continuity is so important."
