Melbourne Victory got off to the perfect start with Archie Thompson scoring the opening goal just seconds from the kick-off, after James Troisi and Gui Finkler linked up well, Troisi found Thompson who smashed it home easily.
29 minutes in and it was 2-0 as Troisi received the ball and ran in on goal, before chipping over the keeper to give Melbourne Victory the goal that they richly deserved.
Wellington tried to get in to the match, and had some chances, but they were mainly half chances as they struggled to come to grips with the strength of the Victory defense.
Right at the death of half-time, Wellington Phoenix made it three as an incredible sequence of passes allowed Adama Traore to find Kosta Barbarouses, who released Finkler, who was left on-side by the Wellington defense, allowing him to sneak the ball under Jacob Spoonley for a 3-0 half-time lead.
Wellington started the second half much better, holding possession well, but they still could not find any goals as they created chances but failed to put them away.
Right before the hour mark, Wellington were punished for missing their chances again as Troisi lofted a ball in for Barbarouses who was chopped down by Shaun Timms, which saw Timms shown a straight red and allowed Mark Milligan to step up and send the penalty home.
In stoppage time, Wellington Phoenix, did manage to pull a goal back as a corner found Jeremy Brockie, who ended the season with a fantastic volley to make it 4-1 at full time.
The win guarantees Melbourne Victory a home elimination final, while Wellington were in danger of last place, pending the other results.
