The Herald Sun’s Sam Edmund has revealed the true extent of West Coast’s free kick advantage in Perth.

St Kilda coach Alan Richardson has launched an attack on the officiating in Western Australia, telling Fox Footy he got “really frustrated” with the decisions last Saturday night.

The Saints lost the free kick count 25-12 in the 13-point loss to the Eagles, and Edmund has explained how numbers like that aren’t unusual for travelling sides.

“We have been writing this story for a while in the Herald Sun, so I went back and refreshed these stats,” he told SEN Breakfast.

“Since the start of 2011, in matches at home against interstate sides, the Eagles have lost the free kick count in 12 of 72 matches.

“They’ve won 60 of 72 free kick counts against any other side other than Fremantle at home.

“That is roughly 350 more than their next rival Port Adelaide at home.

“They’ve been a good side for most of that time, you need to acknowledge, but it’s out of whack.”

In St Kilda’s past four games against West Coast in Perth, including their most recent meeting last Saturday, the Eagles have won the free kick count 95-39.
