Adelaide has moved back to top spot on the AFLW ladder after fending off Essendon with a 33-point win at Unley Oval on Sunday.

The Crows maintained their undefeated streak, with Brooke Tonon quick to secure Adelaide's first goal of the game - only one minute and 15 seconds in - on the way to the 9.8 (62) to 4.5 (29) win.

Courtesy of a Niamh Kelly (two goals and 15 disposals) buzzer-beating goal at the quarter-time siren, the Crows took the lead into the first break, after Essendon's Ellyse Gamble had responded to Tonon's speedy early goal.

Essendon fought hard to keep a hold of a fiery Adelaide early.

Bombers goalkicking star Daria Bannister levelled the scores in the second quarter with a beautiful banana from a set shot on the boundary following a chase-down tackle.

Just as it did last week, Essendon used heavy pressure and contested ball to slow down Adelaide's attacking game.

While it was reasonably effective, it also stymied their own ability to score.

Crows Co-Captain Ebony Marinoff (23 disposals and 12 tackles) and versatile tall Caitlin Gould landed back-to-back goals near the end of the second quarter, before a ripper of a mark by Gould inside 50 led to another goal on the siren leading into half-time.

After the main break, Danielle Ponter landed another running into goal, despite Bomber Ashleigh Van Loon being hot on her tail.

Chelsea Randall (16 disposals and eight tackles) got on the board after a breathtaking mark and long bomb that sailed over Bomber heads and rolled through the goal.

The Crows added another three goals to start the final term, putting game beyond doubt, before Essendon's Paige Scott scored the final goal of the match - and the Bombers' only major of the second half - late in the final quarter.
