The loss secured the fate of then-coach Matthew Primus, who was sacked, and it marked the culmination of a horror 24-months for the club.
The Power were the Giants' first 'established' victim in the AFL, having notched their first win against Gold Coast earlier in the season.
Coach Ken Hinkley said he hadn't mentioned the loss to his playing group in the lead up to Sunday's re-match.
His assistant Matthew Nicks declared any player entering Sunday's contest with revenge on his mind ought to re-evaluate his priorities.
"I don't think you use revenge in football … forget about the result whilst we're playing, it'll be all about our method [and] what we've worked on, even this last week," Nicks said.
"Then the result will look after itself."
Nicks said last year's failure could be talked about, but that to discuss it and learn from it was very different to getting caught up in the emotion of the defeat.
"It's not something we're hiding away from, I think the guys who did play in last year's game came away – it was a really hard period," Nicks said.
"We've got to make sure we learn from that more than anything.
"It's not so much about dwelling on it, it's about 'let's learn from the experience'.
"We're a very different side to what we were last year."
Nicks said the club had addressed its poor starts this season and made changes accordingly before its round 10 match against the Western Bulldogs.
The Power hadn't re-invented the wheel, but by allowing players greater freedom to warm up how they want to warm up they appeared to hit the ground running.
Port led the Bulldogs at quarter and half-time, before slumping to its fifth-straight loss before its bye.
"The last game we played against the Bulldogs we came out and changed a few things with the way we prepared pre-game and we thought that worked really well for the group," Nicks said.
"It was just a few small things within the last half an hour or an hour prior to the game.
"Some of the little warm up stuff … a lot of that's been structured throughout the season and probably in the last week or so we've tried to allow our players a little more freedom so that they can work on what they want to work on.
"It's not massive, but it seems to help our players.
"We know [GWS will] come out red hot, they have in every game they've played.
"They're a very good young side, we know when they're fresh and they're up and going the heat's going to be on."
