The influx meant the Ticketmaster website and phone lines had people on hold for tickets for up to 20 minutes, with fans hoping to snap up thousands of seats to see their team try to make its way through to its inaugural grand final.
At Subiaco Oval, the line to the ticket booth was up to 100 deep, with many camping out to try to secure the best seats.
Saturday’s match holds much importance for the Fremantle Dockers.
Up against reigning premiers Sydney, the Dockers should go in favourites with a fit and firing team that has just had a week off, while Sydney has a mounting injury toll and is bruised and battered after last week’s semi final against Carlton.
In what is expected to be a full Subiaco Oval, should the Dockers win, they will be into the first grand final in the club’s history, playing either Haw-thorn or Geelong.
The Dockers are expected to field one of their best teams of the season as players are fit at the right time of the year.
The only players who could be in doubt are Nick Suban, who injured an ankle in the game against Geelong, Michael Johnson, who missed the Geelong game with a calf injury and Garrick Ibbotson, who continues to try to get over an Achilles injury.
The game starts at 5.45pm.
