JUST when you thought John Farnham had done it all, the legendary Australian performer has bobbed up as the inspiration for Adelaide's NAB AFL Women's premiership on Saturday.

Or so Crows coach Bec Goddard beamed post-match.

Goddard's Crows were deserving six-point winners over the Brisbane Lions at Metricon Stadium in the first-ever AFLW decider after hanging on grimly in the final minutes.

Following the landmark win, Goddard said Farnham's famous song "You're the Voice" had been a Crows catchcry all season.

"Erin (Phillips) and I really love John Farnham and early in the piece we forced it (the song) on the young girls and they've grown to love it as much as we have," Goddard said.

"It's quite true, we are the voice of this competition and we had the chance to turn the pages over from a football history that's been missing with women playing it at the elite level.

"It was our chance to write the story.

"We've got that little part of history, that we've made the best and lasting first impression of season one."

Goddard admitted to being a nervous wreck in the final minutes as the Lions continuously surged into their forward 50.

She described the win as "amazing", paying tribute to the travelling Crows fans from South Australia and the Northern Territory, who played their part in a hefty crowd of 15,610.

"We knew it was going to be four long battles and we were really confident in how we attacked and how we defended," she said.

"The siren went at just the right time.

"There was a fair bit of sweating in the box with about five minutes to go, I can tell you.

"We were in the biggest fight of our lives with Brisbane, they're an amazing opponent and we knew that was going to happen and we just had to get that ball a little longer and stop kicking so shallow.

"Their defence was unbelievable."

Goddard said despite having the run of play for much of the game and not being able to fully capitalise, she remained confident in her team's ability to compartmentalise and attack each quarter with just as much vigour.
