It's not quite winner-takes-all but plenty hinges on the deferred Sydney FC-Melbourne Victory W-League clash to be played on Wednesday night.
While finals teams have been decided, with Brisbane, Sydney, Victory and Canberra filling the four spots - there's still some shuffling to be done among the top three.
A win or draw for Sydney (25 points) on Wednesday will see them declared premiers while the hot Victory (23) can also move top with a win.
The only certainty is that the Roar (25) won't be in top spot after that match.
The Queenslanders finished the regular season in style with a 3-0 win on Sunday over Newcastle thanks to goals from Kaitlyn Torpey, Emily Gielnik and Mariel Hecher, but they can only come second.
A loss for Sydney will see them slip to third on goal difference, forgoing a home final in the process, while Victory are in the same position with defeat or a draw.
All this of course assumes there are no COVID-19 impacts on hosting rights.
It could have been so much simpler for Sydney had they beaten Canberra (22) on Friday to move to 27 points where the premiership would have been a lock.
The 0-0 result meant Canberra knocked the desperately unlucky Adelaide (22) out of finals contention on goal difference and took fourth.
That stalemate pushed the focus to Wednesday night at Sydney's Cromer Park where the Sky Blues will face a rampant Victory.
The Melbourne side are the form team of the competition with four wins and a draw from their last five matches, punctuated by a 6-0 demolition of Perth Glory on Sunday.
While that came as little surprise given last-placed Glory managed just a solitary draw for the entire season, it was still a highly disciplined showing from Victory with Melina Ayres and Kyra Cooney-Cross both scoring doubles.
On Thursday, defending premiers and champions Melbourne City wrapped up a disappointing season with a 2-1 win over the Glory.
They'll finish the competition in seventh place.
