Fremantle are the only AFLW team with maximum points after a third round which produced one of the competition's biggest ever boilovers and a draw in the first Queensland derby.
The Dockers had 93 less possessions and 13 fewer inside-50 entries in their three-point home win over another previously unbeaten side in Collingwood, who also had the six highest possession getters.
One plus for the Pies was the strong form in the ruck of former Diamonds' netball superstar Sharni Layton.
While Fremantle head conference B, Brisbane lead the other after a thrilling 28-28 draw with Gold Coast at Metricon Stadium.
The Suns overcame a 15-point halftime deficit and held the unbeaten Lions goalless in the second half.
Another first-season club, St Kilda, broke through for their first victory with a five-point win over premiership favourites Melbourne to cause one of the biggest upsets in the competition's history.
Rated a $101 shot to win the flag, Saints triumphed 3.1 (19) to 1.8 (14) against the wasteful and inaccurate Demons.
Melbourne's loss was compounded after Maddy Guerin appeared to dislocate her kneecap and Irish rookie Sinead Goldrick suffered a second quarter concussion.
Carlton are third in conference B behind Freo and Collingwood following a 21-point win over a Western Bulldogs side which finished the game three players down, with Angelica Gogos (knee), Deanna Berry (concussion) and Aisling McCarthy (cut lip) all unable to run out the match.
Adelaide's premiership defence gathered more momentum on Sunday as they made it back-to-back wins with an 11-point victory over Geelong at GMHBA Stadium.
Danielle Ponter kicked four goals for Adelaide, though they remain outside the top three in conference A.
The Kangaroos and Giants moved into the top three of that conference with emphatic wins on Sunday.
Forward Rebecca Privitelli kicked a club record-equalling three goals in the Giants' 28-point home victory over winless West Coast, who didn't score until the final quarter.
The Kangaroos bolstered their AFLW premiership credentials, with a 56-point win over Richmond at Ikon Park, with Emma Kearney kicking three goals for the Kangaroos.
The Tigers, Eagles and Geelong are still seeking their first win, though the Cats on Sunday kicked 6.2, their highest score.
