Collingwood has gone down by 30 points in its practice match against Fremantle on Saturday.

Wild weather swept the Western Australia capital city on Saturday morning as the Pies were greeted with thunderstorms at Fremantle Oval in Perth, for their last hit out before Round One.

Despite the rain, small forward Grace Campbell's class shone through with a brilliant finish on the run to open Collingwood's account.

180cm tall Erica Fowler then gave the visitors their first lead of the day with a brilliant set shot from just inside fifty.

That gave the Pies a six-point lead at the first change, with the opening to the second term a scrappy affair as the rain pelted down.

The first flash of lightning half way through the term halted play as both sides headed into the sheds just before the scheduled half time. 

Played resumed with just over three minutes remaining in the half, with the ball thrown up from the exact position it was called off.

The Pies held a three-point lead at the main break after a bizarre first half of football, as midfielders Brittany Bonnici and Imogen Evans led the way with great contested play. 

Fremantle controlled the third term with the Pies unable to generate as many inside fifties as they had in the opening two quarter, with the visitors trailing by 11 points at three quarter time. 

The last quarter was much the same as the Dockers kicked away, with the final margin ending at of five goals.
