Double the price for new green

I am 29 years old and had my licence for more than 10 years with no accidents. When I went to renew my greenslip the price was $627. This was nearly double what I pain last year!!!. I was living in christchurch several years before (under 25 at the time) and paid $650 for full comprehensive insurance. The system in NSW is a joke and why are the insurance companies allowed to get away with this ??
