GEELONG has fallen to an impressive West Coast by 39-points on Sunday in Perth.
A magical three-goal second quarter from Eagle Imahra Cameron set up the 8.5 (53) to 2.2 (14) win at Mineral Resources Park on Monday.
The result left Geelong winless after seven games, while West Coast now have two victories to their name.
Cameron finished with three goals from six disposals, while Irish sisters Grace Kelly and Niamh Kelly kicked two goals apiece and created numerous other attacking forays.
Grace Kelly limped off with what looked like a groin injury after booting her second goal of the match in the final quarter.
Geelong were best served by Amy McDonald, with the star midfielder tallying 24 possessions, nine clearances and a goal.
But it was slim pickings after that, with the Cats outclassed all over the field.
"We thought we'd be able to put up a bit more fight today," Geelong coach Paul Hood said.
"We really struggled to play with the energy we'd like for long periods, and that's the disappointing part.
"It was a step backwards, but we'll work on them and try to fix them."
Eagles skipper Emma Swanson faces a nervous wait for her heavy shepherd in the dying minutes that sent Georgie Rankin crashing to the turf.
Rankin lay dazed on the ground for more than a minute before being helped off.
West Coast dominated the opening term, but their wayward kicking meant they came away with just four behinds to their name.
Two of those were touched just before the line, while they had another two shots that didn't even register a score.
Cameron turned the match on its head in the second quarter with a series of dazzling moments.
She booted her first goal courtesy of a mark at the top of the goalsquare, while her second came when she ran on to a loose ball and snapped truly from 35m out.
The destruction was complete when she took a big pack mark and duly converted from 30m out, with West Coast heading to half-time with a dominant 28-1 buffer.
Geelong's first goal of the match didn't come until the dying seconds of the third quarter, when McDonald twisted and turned out of trouble to kick a spectacular goal.
But the scoreline was already 40-1 when she kicked that goal, with the match out of reach.
