They'll pay you the bare minimum. Keep in mind that unless you're 18 and above, you don't get the full minimum wage. Its a tiered system. Below 16 years of age its something like $9/hr, and between 16-18 its something like $12/hr. Once you hit 18 you get the full amount.
(Note all amounts are pre-tax. Don't get me started with Superannuation deductions)
Not that most people here are that young, but before I have someone screaming that they're being scammed by their employer because they're not getting the $15/hr.
Its a personal decision to work cash in hand and be underpaid, but don't come complaining that your Chinaman employer haven't paid you for months. If you want the protection of the law you need to comply with it.
For the record, McDonalds (and other fast food employers) have been caught in the past underpaying international students, probably with the assumption they can get away with it as international students usually are poorly aware of their rights (and obligations). Dob them in through, and Fair Work Australia will usually compel them to pay up.
alright! thanks man. I'm 20 years old this year so what amount should I be expecting? Approximately?
