YES!!! But i think you will find that you do not get a payslip that outlines the above mentioned deduction (or one at all)
A detailed pay slip outlining all deductions is a legal requirement in Australia. If what you have said is true, I would report them to the Australian Taxation Office as there is a very hefty fine and they don’t treat offenders lightly especially if they are dodging paying workers income tax to the ATO by doing this.
