Big W Whitfords has a couple of the following;

1) Fortress Maximus - head to party supplies in the back corner, turn and face toys, top shelf, can't miss it.

2) Victorian - down in the front, near the main aisle (where confectionery was). About two aisles in from the main aisle (if memory serves). Lowest shelf, stacked.

3) Devastator - two in the clearance section near the front checkouts.
