No if it's fresh into the country, it needs to be stock standard, not just roadworthy.
Diamondwood, PM DRIFTT for help, and be prepared to spend a lot of money to pull everything off, replace with stock parts, and put the aftermarket gear on. WA Dept of Transport are giving you a hard time because that's the rules, and your car is nowhere near meeting them!
If you bought this car through a broker or import dealer, ring them up and abuse them for being so stupid, then ring the compliance workshop and warn them that they're probably going to be getting a call from DoTaRS.
