In fact, it will be the first time the club has had two grades playing finals, as the reserve-grade side has never made finals in the Canberra competition until now.

The women's side will also play finals in their first season of competitive football.

Club president, Arlo Ireland, said he's noticed a culture change since the start of the women's side.

"Having the women's team has been great for our culture, but for them to make finals in their first year is a massive accomplishment," he said.

"It's also the first time our ressies will play finals since we moved to Canberra, and I think that's been fed by the new culture at the club.

"Our seniors are backing up for their fourth-straight finals series, which is a credit to the players and the coach."

Ireland said he wouldn't have drawn the season up any better at the start of the season.

"I was hoping we'd get two grades in the finals this season, and that would have been an achievement," he said. "If you'd told me that all three grades would be playing a home final together, I would have told you that was nearly impossible.

"You really couldn't start a finals campaign in a better situation, and it might give us a platform to surprise some sides this year."

Ireland said all three grades were a strong chance of playing in this year's grand final.

"I truly believe the women are a contender to win the grand final," he said. "The ressies haven't beaten ADFA yet, but we've gone close both times.

"Mick Kenny could lead any senior team to a premiership. He's strategic, smart, and he knows how to time his run.

"I think we've got a good chance at having all three grades in the grand final."

Ireland called on footy fans to build a fantastic atmosphere on the day.

The Seahawks will be on parade this weekend," he said. "You put all three grades in a final on a beautiful, South Coast day, the atmosphere should be spot on.

"Our plan is to have a family meal at the club on Sunday night to try and keep everyone around.

"We also have juniors playing finals in Vincentia, so we're trying to make sure their games are early enough to get back for the seniors."

The women will kick off proceedings at 10am against the ADFA Rams, followed by reserve grade at 12pm against ANU.

The seniors will wrap up the day at 2.15pm against the Woden Blues.
