Queensland is through to their second consecutive Super W grand final after defeating the Brumbies 39-10.
It was a hard fought victory for the home side as the Brumbies dominated the first half exchanges.
Queensland had uncharacteristic errors that put them on the back foot and under pressure defensively.
However, the Brumbies lost two of their top players with forward Tayla Stanford stretchered off midway through the first half before captain Shellie Milward was taken from the ground following a shot from Ana Fotu that earned her a yellow card in the second half.
In the end, the difference would be in the depth of the Queensland side with teenager Alysia Lefau-Fakaosilea, Millie Boyle and Lori Cramer all having important contributions in the win and their second-half performance.
In the final 40 minutes, the team in maroon scored four tries and survived going down to 14 players in the same period.
The match finished in a flurry with Millie Boyle and Ash Turner both crossing to all but seal the win.
"We were a bit unhappy with the rest of our games, we had good games and wins but we hadn't been able to string 80 minutes together, I think we did that today," Queensland captain Kiri Lingman said.
"Obviously it's been in the back our minds [loss in 2018] since the beginning and that has been our end goal so to have another crack at it we're excited."
Super W fans will be set for the fourth instalment of the old-school rivalry between Queensland and NSW come Sunday 4:30pm AEDT at Leichhardt Oval.
The two rivals met at Leichhardt Oval earlier this month where NSW prevailed 15-12 and are yet to lose a game in two seasons.
The 2018 final saw the match go into double-overtime with the Waratahs taking the win.
The match will also be broadcast LIVE on FOX SPORTS, Kayo Sports, RUGBY.com.au and on radio through ABC Grandstand digital and RUGBY.com.au
