Port Adelaide continued to defy the Subiaco Oval hoodoo after hanging on for a thrilling three-point win over West Coast.

Perth has become a grave-yard for visiting teams in recent seasons with both the Eagles and Dockers enjoying outstanding home records, but Port Power have now won six of their past seven clashes in Western Australia.

Acting Port captain Warren Tredrea kicked five goals as the visitors won 18.10 (118) to 17.13 (115), withstanding a furious late charge by the home side to continue their unbeaten start to the year.

Despite finishing minor premier the last two seasons, it's just the second time Port has won its first two games following last week's thrashing of Essendon at AAMI Stadium.

Power led by as much as 29-points in the third quarter before West Coast made a late run, with the clock finally beating the Eagles after they had kicked the game's last four goals.

West Coast will rue hitting the post three times in the last term, two from point blank range as the Power hung on for the victory.

It took almost seven minutes for either team to make inroads on the scoreboard in an extremely tight opening, with both midfields showing promising signs.

But the two sides struggled to make an impression inside 50m until Port centre half-forward Tredrea finally got the visitors' first goal, beating Quinten Lynch and finding space in the left forward pocket to open the scoring.

West Coast quickly replied through Phil Matera and the game began to open up, with Dean Cox prominent in the ruck for the home side and Chad Fletcher and Chris Judd starting to find the football through the centre.

When Ashley Sampi kicked the first goal of the second term West Coast looked in control but Port showed its quality with three goals in five minutes to suddenly turn the game on its head.
