Cow bells and clappers ready as fans rally behind Capitals

"My father was involved with the club as a court announcer since the club’s inception until 2001. I am a die-hard fan. Love the club, game and league," she said.

So far this year Ms Corey has travelled to Townsville, Sydney, Bendigo, Dandenong and Adelaide to watch the Capitals play.

She will be one of thousands of Canberrans cheering their team on and hoping to right the wrongs of earlier in the week when a questionable refereeing decision in the dying seconds of the game sent the Capitals to a nail-biting third game WNBL title decider.

Support has been steadily growing for the Capitals since Wednesday's disappointment, following their one-point loss to the Adelaide Lightning.

Within 20 minutes of tickets going on sale on Thursday, more than 2000 Capitals fans jumped on the opportunity to watch the team play in a game expected to sell out.

The 31-year-old was courtside at Wednesday night's controversial game at Adelaide Arena, when the Capitals lost to the Lightning, 74-73, on the buzzer.

"The game started with much anticipation. During the game there were many ups and downs, but the end of the game was purely gut wrenching for the team," Ms Corey said.

"The Adelaide crowd were very loud."

Ms Corey and nine friends were among the first to secure their tickets early on Thursday morning.

Having watched the Capitals win three of their seven titles, she is hoping to witness the team claim an eighth at the weekend.

"The players, coaches and staff have worked very hard this season to get to where they have and [the eight title] would be the cherry on top," Ms Corey said.

"We will be at the game dressed in team shirts with Caps, hand clappers and cow bells, which we've held for the past few seasons."

The finals decider is set to have the biggest crowd in the league for the 2018-19 season.
