Leaders Sydney FC and second-placed Perth Glory have already secured passage to the finals, while third-placed Canberra United have one hand on a ticket.
Melbourne City’s run of outs, which now stretches to five matches, has kept the door open for both Brisbane Roar and Newcastle Jets, but the match at McDonald Jones Stadium is surely a must-win in the third-last round of the regular season.
Both teams revived their fortunes last round after a mid-season bump, with the Roar now just a point off fourth.
The Roar will arguably start as favourites after a morale-boosting 3-0 win over Western Sydney Wanderers.
The Jets have earned just three wins over the Roar in 12 attempts, though they remain undefeated over the past three meetings.
Tune in for the start of the TV broadcast at 2pm on Sunday on Fox Sports 505 and ABCTV.
