As the AFL takes control of the finals game-day experience, the Power were concerned that they may not have been able to play the INXS anthem which they have used during the home and away season to pump up the home crowd 60 seconds before the bounce.
But the League has softened its view and agreed to permit the Power to run with the countdown song.
Port CEO Keith Thomas said the club was delighted with what he described as "a terrific coup for supporters".
“This decision will be warmly welcomed by all of our members and supporters and, I’m sure, the wider football industry.
“Never Tear Us Apart has resonated so strongly with our people because it reflects the history and culture of our club, and we keenly await the AFL’s final decision on the matter.”
Final sign-off on the song may still rest with Port's greatest rivals, should the Power and Crows come up against each other in the first week of finals.
Thomas said he was hopeful that Adelaide would endorse Port playing its anthem before the game in the interests of sportsmanship and goodwill.
“I think Adelaide does understand the importance and significance of the song to our people, and I’m sure they’d endorse and support us playing it before the game."
