you'll probably have better chance (if you don't have much experience) as a receptionist, data entry, or administrative assistant. These sorts of roles earn about 25-40K a year. Later, you can be team administration or a PA, which earns about 30-60(ish?)K a year... full time roles. They also look very sexy on your resume if you want to be a secretary....
While you study, admin roles that I first suggested, as a casual you earn about $12 - 25 an hour..... It's what I'm doing while I study.
seriously, doing administration, I've developed a 65w/m typing speed. It's insane.
