Nope, I'd say you're doing pretty well to get that much. When I was starting out at the same age, I was getting minimum wage working for a certain nameless ISP - they didn't want to pay us as call centre workers (award was $18) so got us to do a few other minor tasks, so when business sa came in and audited the place, they classified the job as "Office Clerk" which the award was $13 at the time...
Needless to say, I shed no tears when leaving that place.
