There's a big, big sound from the west of Sydney after last year's wooden-spooner the GIANTS continued to stake an unlikely claim for a berth in the NAB AFL Women’s Grand Final on March 24.

This mean's Friday night's game at Blacktown International Sportspark is the biggest in the GIANTS' short AFLW history.

Incredibly, five teams remain in contention for the two Grand Final spots with just one round remaining.

Two big upsets in round six – Brisbane going down to Collingwood at home and the GIANTS defeating ladder-leaders the Western Bulldogs – means there are three "live" matches in the final round.

What each team needs to make the Grand Final

Western Bulldogs (1st, 16 points, 143.4%) – a win over Melbourne will guarantee a Grand Final spot, otherwise the Dogs will be sweating on both Adelaide and the GIANTS losing, and Brisbane winning by a small margin.

Melbourne (2nd, 16 points, 119.3%) – defeating the Bulldogs will sew up a Grand Final position. If not, the Demons will be relying on Adelaide and the GIANTS losing and Brisbane winning by a small margin.

GIANTS (3rd, 14 points, 112.4%) – a win against Brisbane (at home, in Blacktown), along with Adelaide losing, will see the GIANTS leap-frogging the loser of the Western Bulldogs-Melbourne into the Grand Final. A draw will see percentage come into play.

Adelaide (4th, 14 points, 101%) – beating a suddenly rejuvenated Collingwood (away, at Olympic Park Oval), plus the GIANTS losing, will be enough for Adelaide to take its spot in the Grand Final over the loser of the Western Bulldogs-Melbourne game. A draw will result into percentage determining spots.

Brisbane (5th, 12 points, 107%) – needs to beat the GIANTS (away at Blacktown), Adelaide to lose, and Western Bulldogs to defeat Melbourne by a fair margin to overtake the Demons on percentage and reach the Grand Final.

There remains the highly unlikely chance of Melbourne and Western Bulldogs drawing, and Adelaide and the GIANTS both winning, meaning the top four teams would all finish on 18 points. In that case, the Grand Final spots will come down to percentage.
