The Power stunned the Sydney Swans at AAMI Stadium, matching the reigning premiers at their own game to race home 30-point winners, 15.12 (102) to 10.12 (72).
After winning last year's flag and establishing itself as the AFLs toughest side, the Swans were pushed and ultimately defeated by a new-look Power outfit that last year wouldn't have kept up with such opposition.
While it was an ugly game, the stats were telling; the Power led the Swans in contested possessions 145-138 and inside 50s 54-43, while tackles were almost even at 77-78.
Swans coach John Longmire was hesitant to praise his opposition too much, claiming it was too early in the year to really offer any judgment.
"I thought they were pretty sharp … it's really hard to measure, it's not until you get well into the season that you actually get a feel for it," Longmire said.
The reigning premiers looked sharper and more dangerous when in possession early, but missed a host of opportunities to go ahead, booting 3.5 in the opening term.
Port Adelaide on the other hand made the most of any chance it got, kicking four goals straight to take a narrow lead into the first change.
Adam Goodes was held to just one handball by Tom Jonas in the first quarter but exploded in the second, to finish the half with 13 disposals.
He ended the match with 19 disposals and two goals.
Josh Kennedy registered a triple-double with 34 disposals, 10 tackles and 11 clearances but each time the Swans looked like kicking away the Power responded, moving the ball quickly and with far greater confidence than it has for the past 24 months.
Power captain Travis Boak was outstanding for the home side with 29 disposals and three goals, as was Brad Ebert (25 touches and a goal).
Longmire said the Swans needed to fine-tune a few things in order to hit round one running.
"We need another couple of strong weeks of training to make sure we're competitive in that first couple weeks because we know we need to be," he said.
In his comeback game, injury again struck Power forward John Butcher, who could have a cracked bone in his hand.
It's another setback in a long line of injury problems for the 21-year-old, but Hinkley didn't think the latest issue would keep him from round one.
