Adelaide has produced a final-quarter fightback to keep its NAB AFLW defence barely alive with a draw against Greater Western Sydney.

Both teams battled hard in teeming rain at Blacktown in Sydney's west, where the Crows trailed for most of the game which finished 2.7 (19) apiece.

The Crows are last of the eight teams on percentage behind GWS, with both clubs six points outside the top two with three rounds to go.

Conditions made it hard to produce flowing passages of play and handle the ball, and especially difficult to take marks.

Much of the march was conducted at ground level, where both teams scrabbled furiously for possession in front of 2,409 spectators.

Trailing by nine points at the last change, Adelaide scored the first ten points of the final quarter, before GWS notched a behind to square the contest.

Each team kicked one goal in the first quarter, with Rebecca Beeson hitting the target for GWS and returning vice-captain Courtney Cramey replying for Adelaide as the teams went to the break locked at 1.1 (7).

Lively GWS forward Cora Staunton kicked the only goal of the second quarter from a free kick, with the Giants leading by eight points at the long break.

Scoring became even tougher in a goalless third quarter in which the Giants added two behinds to the Crows' one.

Adelaide's Ruth Wallace slashed the gap to two points early in the last quarter with a goal from an opportunistic snap followed by a behind, as the Crows dominated the early minutes of the term.

Ebony Marinoff starred for Adelaide with a remarkable 21 tackles, the most ever in an AFLW game.

Alicia Eva was superb for GWS, notching 22 possessions (nine more than any other Giant) and laying six tackles.
