Their winning run ended in Round 14 when they lost to South Fremantle at their home ground, Bassendean Oval by 19 points.
However, South's centre half-back Joe McKay failed in his Supreme Court bid to be cleared to East Perth.
After a loss to East Perth in round 6, coach Mal Brown resigned due to his perception that his personality was affecting the umpiring and the "unreceptive attitude of the players to my advice".
The following week in the Second Semi Final, South Fremantle continued their unbeaten streak, beating Swans by 10 points.
However, in the second quarter, South Fremantle dominated, kicking eight goals to one, to lead by 54 points at half time.
