Born into one of Gunnedah's preeminent sporting families, the daughter of Bulldogs founder Brian Lenton finally got the chance to play AFL this year.

Fisher, a 43-year-old mother of three, will forever be known as a member of the Bulldogs' first women's side.

And at Wolseley Oval on Saturday, Fisher and her teammates will attempt to turn a "dream" debut season into a fairy tale by beating the Swans in the grand final.

Lenton will be watching the historic clash, as will Fisher's sons, Chad and Jake.

The brothers, aged 13 and 10, play for the Bulldogs' under-14 side, who are also in their foundation year and will confront the Roosters in the first finale on Saturday.

It's a proud sporting dynasty that includes Fisher's brother, Nathan, named among the Bulldogs' best-ever 22 players when the club celebrated their 40th anniversary in 2017.

Brian Lenton, who coached Gunnedah to five of their seven premierships, was also named in that team and is considered the club's finest player of all time.

Fisher said the Bulldogs' men, women and juniors making the grand final was "extremely special" for her family, especially for her father.

"That's who I'm excited for," she said, adding that he was on "cloud nine".

Having three teams in finales is "unbelievable", she said, and grand final day will be "spectacular".

"We've gone from not even thinking that we can play any sport [because of COVID] to, 'Here we are, looks at us!' ... It sure is a dream year - and it's great for the town."

Fisher is "so excited" for her sons and their teammates, describing them as a "good bunch of kids".

As for herself taking a big step into the unknown this year, she said: "I don't know why, at 43, I thought I could do this. But I just thought, 'Why not?'

"It's been in my family for many years, so I thought, 'Let's have a crack at this."'

Fisher, who owns a hairdressers, said she would be playing for her father on Saturday.

"It's the club he started, and hopefully we become the first women's side to win a grand final for Gunnedah," she said. "I can brag with my father and brother then."

Fisher is part of the Bulldogs' leadership group and, according to the side's co-coach, Sam Proudfoot, she was a "natural choice" to be named captain for the opening match of the season.

"Not just for her lineage but for her individual qualities, which inspires and lifts those around her," he said.
