In their ninth straight grand final of the 12-year-old competition, the champion Wagga side added eighth crown with a 26-0 victory at Equex Centre on Sunday.

The Dragons were the only team to beat Brothers all season, downing them in both regular season clashes, but Brothers responded in the finals series to down them in the two biggest games of the year.

Coach Craig Stewart was blown away by the scoreline on the way to another triumph.

"It was unbelievable," Stewart said.

"I really enjoyed that last 10 minutes that's for sure but I think we really stuck to our game plan and they just played really well.

"They were just up for it."

With the strong rivalry between the two sides Stewart admitted Brothers had been practising field goals all week, but a play similar to the match winner in their 2017 crown wasn't required.

A fast start help take the game away from the minor premiers.

Three minutes in Brothers capitalised on a mistake from three-time league medal winner Emily Perrot as speedster Sophie Crouch crossed out wide.

Jess Absolum then made it a 10-0 game when she scored after 10 minutes.

Starting well was part of Stewart's plan to their make the most of their vast grand final experience.

"We thought we would try to get that fast start and if we could, as they are a pretty young team, we thought with our experience we could hold them," he said.

Sarah Carter then scored after kicking ahead for himself three minutes from the break to give Brothers a 14-0 buffer.

Her father thought it was a crucial play.

"I think that gave us a lot more confidence going to the second half," Stewart said.

Brothers didn't take their foot off the pedal with Brooke Wiggett crossing for a second half double on her way to being named Leo McCarthy Medal winner.

In her second season with the club after making the move from Tumbarumba, Wiggett never expected the individual accolade and was just pleased to play her part in the team's victory.

"It was pretty surprising," Wiggett said.

"It's tough out there but you just do what you can."

Her goal kicking was another highlight of the game, slotting three of her five attempts.

She's loved every minute of her time with the club, especially being part of two premierships.

"It is a totally different experience ," Wiggett said.

"Everyone in the background is amazing and they support you no matter what.

"Everyone is behind you."
