It depends on what kind of job it is. If you're about 18-19 years old and get a job in a Supermarket, the minimum wage is about $14-15 an hour I think. A newly trained hairdresser would get about $ 16-17.

My friend's son just got a job at the football stadium, selling beers, chips etc. he gets $19 an hour. He's 18 years old.

Well, those are the lowest paid jobs I can think of.
