It was only announced less than an hour before kick-off that the match would be delayed one hour due to the intense heat-wave that has rocked much of the country.
2 hours before the scheduled kick-off time it was 40 degrees, the delay was welcomed by the players but as the match began it seemed only Perth was able to deal with the conditions.
If any moment was to sum up Adelaide's season, Iacopo La Rocca's inexplicable own-goal might be it.
Attempting to head the ball clear, he misjudged, possibly the flight of the ball, possibly the position of the goal, possibly his own position on the field, possibly all of the above. The one certainty was Perth won't get an easier lead as La Rocca headed the ball into his own goal with a shot that would have made any striker proud.
Diego Castro was in fine form all night and doubled the Glory's lead in the 37th minute with a trademark goal.
Almost identical to the week before, the Spanish playmaker picked the ball up inside the box to the left of goal, cutting inside with ease before burying the ball inside the far post.
Castro was at it again in the 46th minute, setting up the over-lapping Andy Keogh who finished easily to make it 3-0.
Reds fans might have hoped for a better performance in the second half, but those hopes were dashed in the first minute after the break as Adam Taggart scored Perth's fourth goal, capitalizing on poor defending from Adelaide.
Man of the match Castro wrapped up the win in the 88th minute to make it 5-0 and hand Adelaide their worst defeat of the season.
The defending champions remain bottom of the ladder with just two wins and 11 points, meanwhile Perth moves up to fourth with 27 points - overtaking Melbourne City on 26 points with a game in hand.
