Newcastle Jets ran riot against Brisbane Roar at Suncorp Stadium, handing the home side a 6-1 hammering.
Roy O'Donovan and Joey Champness both scored twice in the penultimate round clash between two sides who have failed to make the A-League Finals Series.
It was Brisbane's record home defeat and confirmed that the Roar will finish next to bottom in the table.
The Jets, who made it five consecutive wins over Brisbane, took control with two goals in a four-minute period midway through the first half.
Winger Champness sliced open the right side of the Roar's defence before cutting inside firing a shot that was deflected into the corner of the net.
The youngster then went around the outside of Daniel Leck to tee up O'Donovan's instinctive finish.
Jamie Young made a good save from Angus Thurgate to keep Newcastle from adding to their tally before the interval.
Darren Davies' team pulled a goal back four minutes into the second half when 18-year-old Jack Duncan followed up to net after keeper Lewis Italiano had failed to hold a fierce Dylan Wenzel-Halls strike.
Six minutes later O'Donovan had his second of the night when he headed home Ivan Vujica's cross, and the visitors scored twice more in a three-minute spell.
Kaine Sheppard's left-footed strike deflected in off the head of Dimitri Petratos to make it 4-1 and Champness tapped in to complete his double.
Substitute Kwabena Appiah-Kubi rounded off the scoring in added time, tucking away a one-on-one.
It was a particularly disappointing night for the Roar given that they hoped to send captain Matt McKay off into retirement on a positive note.
McKay will make his final appearance in the final round clash at home to Adelaide United.
Meanwhile, minor premiers Perth Glory are 13/10 to win the Grand Final. Sydney FC are priced at 2/1 with Melbourne Victory 5/1.
