Her family's idyllic property is the perfect place to keep a clear head.

The 22-year-old, who is aiming for her first open grade premiership, said her team was keen to turn the tables after losing the 2018 decider to the Saints.

"I think we're coming into this grand final with a better mindset and with better game play," she said of the clash at Reid Oval.

The Blain family's Timboon-based block of land has first-time visitors astounded by its beauty as they approach.

There's strong Friesian heifers on the right and lush green grass on the left as they roll up the long driveway.

The big sandstone house is like gold on top of the hill.

Guests can park beside a rusted tractor ornament behind the house.

They soon find out there are plenty of characters roaming around the property.

There's the curious black cat Bundy, Labrador Bella and Scar and Scabs are among the heifers.

The family, which was previously based at Cooriemungle, built the property about six years ago.

It's been Blain's base during the Bombers' dominant season.

Cobden, which finished on top, progressed to the decider after beating Warrnambool by two goals in the second semi-final.

The wing attack and centre, whose younger sister Sophie also plays in the team, knows her side will need to bring its best against the reigning premier.

She said one focus would be stopping the ball getting to Koroit's prolific shooter Nell Mitchell.

"We've got to stop that ball in the centre court before it gets to her because you can't really stop her with the overhead ball," she said.

"She's so tall and strong."

Blain, who won a top-grade best and fairest with the club in 2015, said her Bombers played at their best when positive.

"It's just our positivity to keep everyone in the game," she said.

"If someone's got their head down, we just get them back up and go from there."

Blain, who has been part of division one and 17 and under premiership teams, said her group wanted to win an open flag for the club.

"We want to win it for the club, not just ourselves, but everyone at Cobden," she said.

First-year coach Mel Starr, formerly Hamilton Kangaroos, has been one change at the Bombers this season.

She took over the reigns from 2018 playing coach Nadine McNamara.

Blain said have a non-playing coach had been a good addition.

"It's a whole different ball game having a coach on the sidelines," she said.

"She (Starr) can see what needs to be changed from the sideline.

"It's a whole different view on the game."

Blain said McNamara still provided vital on-court leadership.

"Nadine is captain so she can see what needs to be changed on court as well so it's a good mixture," she said.

The midcourter, who has been with the Bombers since under 12s, added the open group had improved its game structures and set plays this year.

Blain works full-time on her family's Cooriemungle dairy farm and is a part-time nurse at Cobden District Health.

The former Timboon P-12 student said it was a juggle to manage her work and sport.

The Bombers beat the Saints twice this season with a one-goal win in round seven and a nine-goal victory in round 16.
