Tickets to the WNBL final are "absolutely flat out," according to a Bendigo Stadium spokesman.
The spokesman said there was a long line out the front of the stadium and he was confident tickets would sell out by the day's end.
He said the ticketing system crashed briefly earlier this morning, with staff having to give people paper receipts rather than actual tickets, but the problem has since been resolved.
This Sunday Bendigo Spirit will play Townsville Fire at the Bendigo Stadium, vying for the championship.
Long Gully resident Jeff Adcock bought two tickets to Sunday's game and said he was excited to support the team.
"I am keen to see the game and show my support," he said.
"I love sport and support most sports teams in Bendigo."
Mr Adcock said he went to the grand final last year and hoped the girls could make it back-to-back.
"I certainly think they can do it but I think it will be a tougher battle (than last year)," he said.
"I think it will be a lot harder."
Mr Adcock said Kristi Harrower was a great player and leader on the court.
"I don't know how the team will go when she retires," he said.
"I am sure the others will step up."
Eaglehawk resident Pauline Gordon purchased three tickets and said she knew the Spirit could win.
"They are fabulous," she said.
"They are a really good team who play well together and they want it."
Ms Gordon said she followed the team throughout the season.
Adult tickets are $49.50, concession tickets are $35 and tickets for children are $28.
