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.
Shots were fired at either end up until the half-time whistle, but Jonsdottir’s opener remained the only goal and Adelaide had the advantage leading into the second half.
There was zero hesitancy from both sides to take on players and work their way into the box. Some beautiful link-up play between Allira Toby and Raso saw the latter intelligently move in behind defenders and stretch out for a chance at goal.
In the 50th minute, Dylan Holmes whipped in a cross at the back post for Jonsdottir, but she was not able to keep her header down.
Raso was clawing for the equaliser as she slid in to try and latch onto a back-pass to Willacy and almost getting there.
Four at the back for the Reds seemed to be working in their favour as the half progressed, making crucial clearances as Brisbane tried to sneak their way in.
Heyman’s goal in the 64th minute was ruled offside in a close call, after some persistent play.
A determined Raso took on and beat two Adelaide defenders to dink a pass to Toby who skied her effort over the bar.
Willacy pulled out a fabulous diving save to knock Toby’s strike over the crossbar and then saved Nagasato’s penalty kick in spectacular fashion on the 86th minute mark to be Adelaide’s saving grace.
It just wasn’t Brisbane’s night in front of goal as Willacy and United’s defence remained headstrong to hold out for the three points.
