Crucially, they maintained their five-point advantage over Melbourne Heart in fifth and need only another point from their final two games to guarantee a home semifinal.
"It wasn't a bad result, to be honest,'' Sigmund said. "It could have been worse. You take that point and run. At least we are still five points ahead of Melbourne Heart.
"That point helps because if we had lost it could have been a lot worse. Considering how poorly we played in the first half, we could have been two or three down. To be only one goal down at halftime and to come back, I think it shows the character in this side. We could have actually pinched it as well.''
Melbourne dominated the first half with some quick counter-attacking and fluid ball movement. They created a host of chances and were rewarded with a goal to Eli Babalj in the 32nd minute when he nodded home a free-kick.
It was a soft goal to concede in the context of the half but Wellington responded well in the second half. They pushed higher up the pitch, pressuring the ball, and had a more even share of possession.
They certainly refused to yield and that was no better illustrated than when a scuffle broke out involving every player on the pitch except both goalkeepers after Andrew Durante went in hard on Jonatan Germano just before the break. Sigmund was at the centre of the action and picked up a yellow card for his troubles.
"I will always look after all the boys,'' he said. "Dura was isolated so I thought I would get a few boys out the way. I think that's what you do as a team. We are a good bunch of boys and we look after each other. To be fair, it was good to see all the boys come in and help each other out. It was only handbags. It wasn't anything serious.''
Wellington remain in Melbourne, where they will meet the Victory on Friday night. A win in Victoria has eluded the Phoenix in 10 games in the state but they are confident after winning four and drawing another of their last six away games.
And they also have Paul Ifill.
