Walyalup equalled a club record with a ninth straight win on Sunday, a 43-point thumping of Essendon at the MCG.
Patrick Voss kicked four of the Dockers' five goals in the second quarter to spur the visitors to a 52-point lead at half time.
The Bombers fought hard after the break, but the damage had already been done as the Dockers won 16.8 (104) to 8.13 (61).
Essendon had only managed 1.8 to half-time in dreary, wet conditions, but rallied with two goals in the third quarter and they won the second half by nine points.
It is the ninth win in a row for Justin Longmuir's side, a club record they will break if they can beat St Kilda on Friday night, and draws the Dockers level with Sydney at the top of the ladder after 10 rounds.
Bombers coach Brad Scott was animated at quarter-time after the Dockers kicked the first three goals of the game and closed out the term with a 25-point lead.
Justin Longmuir's side continued to waltz through the second quarter, kicking another five goals to five behinds and taking a 52-point lead at the long break.
Clearances were 14 apiece at half-time, but the Dockers had kicked 5.3 from that source to nothing from the Bombers.
Archie May finally kicked Essendon's second goal 14 minutes into the third quarter, and a booming 50m shot from Nate Caddy followed for the Bombers two minutes later.
Essendon avoided the humiliation of a huge margin that loomed halfway through the game, but it was small consolation.
Shai Bolton continued his excellent form this season, amassing 24 possessions and kicking two goals, while fellow on-ballers Caleb Serong and Andrew Brayshaw also shone in the gloom.
Murphy Reid had a team-high 29 possessions for the Dockers and seven inside-50s, also kicking a goal.
Bombers newcomer Sullivan Robey kicked two goals and had five clearances.
Small forward Isaiah Dudley, who snapped a great goal in the first quarter, was able to return to the field after he was crunched in a tackle and limped off in the second quarter.
