Have you checked recently? The vsb14 is being up dated, the guy I spoke with which was the head of western Australian department for mods said all other states are the having the same rules with the hp in pre adr cars. Old rules was cubic inch measure and a power to weight calculation. Till they finish updating the vehicle standards this 180hp per tonne is the rule for pre adr cars. However when i asked how long that will be (as I would wait until its updated just incase it changed for my build) he said they have been at it for 18 months so far an couple be a few more years yet. Also he mentioned the 180hp for pre adr cars will stay Australia wide. Be interesting to see if the other states are the same...
