Gunnhildur Jonsdottir's goal was enough for Adelaide to get one over Brisbane in a 1-0 win.
Adelaide finished off their great season on a high and claimed bragging rights, as the loss for Brisbane means they cannot win the Premiership.
For the last time this season, Adelaide made one change to their starting line-up with Kahlia Hogg who made her first start for the Reds, replacing Georgia Campagnale.
Danielle Ward made her debut for the Roar to replace Jenna McCormick, in an experienced starting XI.
The two sides first met in Round 3, where United’s prolific striker, Veronica Latsko, was the difference in a 1-0 win at Lions Stadium.
It was an intense start to the match, with both team’s attacking but neither side could connect a final pass. Hayley Raso looked full of energy on the wing which caused all sorts of chaos for Adelaide’s defence.
Brisbane’s pressure allowed some space to open, and Yuki Nagasato fired a blistering shot to force a save out of Sarah Willacy, who stretched to pull out a fantastic save.
Both defences handled the pressure well until Fanndis Fridriksdottir crossed in for Gunnhildur Jonsdottir grabbed her first goal in Red and opened the account for the hosts in the 13th minute with a tenacious header.
The end to end football continued throughout the half with an endless attacking threat. A promising move for Adelaide ended in Hogg unleashing a forceful drive wide of the right post. Minutes after, Michelle Heyman pounced on the ball to fire her left-footed strike into the hands of Mackenzie Arnold.
Raso almost capitalised on a defensive shake-up to hit a powerful strike over the bar, connecting on Chioma Ubogagu’s cross in the middle of the box.
There was no denying the desperation as many cautions were shown due to the physicality of the game.
