Australia Quick Strike: Flex
I'm not a fan of the standard flex offense, but I do love incorporating the flex action into an offense - especially as a secondary. Here you can see Australia's version of it.
Australia Quick Strike: Double Back Screen
This one starts out with the same basic look. Two wings on a side -corner and wing. The post on the ball side and the trail filling the opposite slot. The trailer (4) screens down for the wing (3) who cuts up and gets the ball. Right as the point makes the pass the post (5) sets a back screen for him. The point then cuts out to the corner, getting an in screen from the corner player (2).
Australian Quick Strike: Elevator
I'm always a fan of elevator plays. They are simple, yet effective, and can be deadly to get your best shooter shots. Australia had a really great wrinkle to it out of their secondary/quick hitter look.
The entry starts in the traditional set of a trailing slot, wing, and corner on one side and the post and point on the other. The trailing four screens away for 3 on the wing. The wing (3) comes up and catches the reversal from 1. The 4 drifts to the elbow. As he passes, 1 cuts off the back screen from 5 to the rim. As he gets there the 2 screens in for the 1 to the corner, the 2 then comes out on the elevator screen from 4 and 5 for the shot.
