For an advlt (above the age of 20) the minimum wage in Australia is $15.15, according to Fair Work Australia anyway.
Depending on the industry. I worked in a metal factory for 3 years (2008-2010) and i was getting paid between $11.15 (when i was 19) to $14.35 (22 when i left)
i knew some people my age that weren't even getting THOSE rates, like my mate who was 21 and getting $12.75.
And yes, i live in Australia, Adelaide in fact. Did you also know that Wages vary from State to State. Like in my Company, A Laborer from Melbourne will get just shy of $30/hour while i'm getting $25.75/hour.
Basic principle is, Avoid Award Rates (They can lower your hourly rate for things like Annual Leave) and IMPORT EVERYTHING FROM AMERICA, much cheaper in the long run.
