when i renewed my greenslip this year, I noticed the asking prices right across the board had doubled for me! I hadn't had an accidents, hadn't lost my licence and I'm pretty sure I didn't fall below the age of 25 (granted that would be freaking awesome!).... but it went from 309 to 619!!!!!
I called everyone and everyone was quoting around the 600 dollar mark, except shannons who were about 200 cheaper.. but still! No idea why it was doubling for me.
