VENUE Gold Coast Stadium.
Port Adelaide gate-crashed Gold Coast Suns' home ground birthday party with a 48-point AFL win.
Barely 12 months after becoming the Suns' first scalp, Port ensured history did not repeat by thumping in seven unanswered goals in a stunning third quarter.
The 17.16 (118) to 10.10 (70) win in front of 12,416 fans dashed the Suns' hopes of marking the one-year milestone of their Carrara venue with a first home victory.
They looked on track by juggling the lead before a slow starting Power grabbed a one-point halftime advantage.
Then all hell broke loose.
Seven third-term goals in 14 minutes - including five majors in just six - ensured Port had doubled their halftime score by the final interval.
Remarkably Port racked up 22 inside 50s to the Gold Coast's 11 in the third term alone to help them grab a match-winning 14.14 (98) to 7.8 (50) lead.
Gold Coast had hoped to break an 11-game losing run at home.
Instead Port marked only their second away win in 14 games since 2011.
Port's initially inaccurate kicking ensured Gold Coast booted the opening two goals - including one in the opening seconds to an impressive Sam Day.
The Power finally woke up in the 15th minute when they kicked their opening major and the floodgates opened as the visitors snatched a 4.4 (28) to 2.5 (17) lead at the first break.
Day opened the second term with two straight goals as both sides juggled the lead before Port held onto a 7.7 (49) to 7.6 (48) advantage at the main break.
Port's pressure and unforgivable Suns turnovers led to the third-quarter mauling that turned the match on its ear.
Gold Coast gave the true believers a glimmer of hope by kicking the first three majors of the fourth term but normal service resumed as Port notched back-to-back victories for the first time since round 22 2010.
For Port, Travis Boak was inspirational with three goals and 28 touches.
For Gold Coast, Day finished with three majors while Harley Bennell, Sam Iles and Danny Stanley all had 25 disposals.
