North Melbourne's preliminary final scare against Melbourne was "ideal preparation" for Saturday night's AFLW Grand Final against Brisbane, coach Darren Crocker says.

The Kangaroos trailed Melbourne by 19 points before storming home to keep their flag dream alive.

The winning margin of 10 points marked what was by far the Roos' closest contest in more than a year.

"We felt like it was the ideal preparation for us, being challenged in that way," Crocker said.

"We looked at a few things this week where we probably got a little bit sloppy in a couple of areas of our game, just because we hadn't been challenged to that extent.

"We've been able to look at that closely this week and hopefully address that and tidy up a couple of things."

On a remarkable 26-game winning streak, the Kangaroos will attempt to become the first team in the history of the women's competition to win back-to-back flags.

North has just about put together the perfect season, claiming most of the major individual awards on its march to the Grand Final.

AFLW Best and Fairest Ash Riddell and AFL Players' Association MVP Jasmine Garner will lead their premiership charge alongside fellow All-Australians Tahlia Randall and Blaithin Bogue.

Brisbane pair Courtney Hodder and Jennifer Dunne also won All-Australian blazers, while the Lions are superbly led by Ally Anderson and Isabel Dawes in the midfield, with Dakota Davidson a possible matchwinner in attack.

Both sides named unchanged line-ups from their preliminary finals, with North midfielder Mia King the hard-luck story.

A mainstay in the Kangaroos' side when fit, King recovered from a knee injury to put herself in the frame for a Grand Final recall, but was not selected.

Crocker said picking King after seven weeks on the sidelines would have been too big a risk and forced too many structural changes to his side.
