UPDATE: The streets of Fremantle are awash with purple as the Dockers faithful hope to cheer their team to victory.
They have come in their thousands, a purple army filling the streets of the Dockers' port city home today.
People have surrounded huge screens on South Terrace, shouting and screaming as their heroes give their all, still hopeful despite the Dockers' slow start in the first half.
A yellow beacon in a sea of purple, Melbourner Kim Thao said she had booked tickets to Perth before she knew the Dockers would make the finals.
"There are a few of us around. Everyone stares at me because I'm wearing a (Hawks) scarf, but I'm like, whatever," she said.
"Walking down the street we had a few people yelling but it's all in good fun."
People are queuing more than half an hour to get into nearby pubs.
The queue at the Sail and Anchor had blown out to about 45 minutes, one punter said.
Local businesses are bracing for a post-game onslaught of hungry fans with extra staff lining the counters at restaurants and bars.
At the Old Shanghai food court, one stall holder said she had ordered in more food in preparation for the post-match festivities.
"Because now I think business in Fremantle has not been so good, but because there's something special, I think all the businesses are expecting (a big day)," said the stall holder, who asked not to be named.
"If Freo win there will be a big celebration, and I expect a lot of people will come."
The Sail and Anchor has closed its upstairs balcony after unruly behaviour from fans.
Patrons were tipping beer and flicking cigarette butts into the heads of patrons, manager Peter Bottcher said.
The bar was still serving and should have enough beer to last through the weekend, Mr Bottcher said.
Some customers have been told to leave the bar.
"Liquor Enforcement officers responded to reports of people on the balcony pouring beer on people below," a WA Police spokesman said.
"As a result, only water may now be served upstairs. Normal service is continuing downstairs."
