The safety cage must be within the passenger compartment, and on late model vehicles, you are allowed to brace forward to the front strut towers. It just so happens that in hatchbacks, the rear towers are within the passenger compartment, so you can place your safety cage where ever you wish. If you have a boot, with the rear towers outside the passenger compartment, then you have a problem.

It has been passed by the WA Eligability Officer, as well as the visiting NSW and Vic EO's that were here for the Nationals.
