Oh yes, most insurance companies are terrible for us males under 25.
I'm with AAMI too and I have the basic $500 excess + another $500 because of my age. When my policy is up I'll be looking hard for one with a lower excess but similar annual fee.
Currently I pay $661 (or around there) with a 10% discount from the safe driving course and because I switched one of our cars to AAMI too

Though the stupid sportback is $50 more expensive a year compared to the sedan!
BTW, check the car properly when you get it back from the repairers. My gf's car still has the bumper sticking out a little from a dodgy AAMI repairer. When we first collected the car they didn't hook up the licence plate lights and something about the front grill wasn't on. Grrr....
