You know wrong then

I live there
I pay $501 per year car rego (per car), of which $264 is a TAC (Transport Accident Commission) which pays for compulsory Third Party Insurance. Any insurance above and beyond that I have to get elsewhere.
Ive got comprehensive insurance on my X1/9 which costs me another $800 a year (cheap for my age, but I'm insured through an enthusiasts company) but any licenced driver is covered driving my car. The only difference is that if you're young, you pay a higher premium if you crash.
The good thing about CTP is that if the car has rego, then you know that you are covered in a crash
WRT the high powered cars MEP, when i got my licence, the rule was nothing over 125kW per tonne, now its no V8s, no turbos, no hi-po 6-cyls until you're off your probationary licence.
