Make sure you have permission to work in Australia and you understand the working conditions of your student visa. For information contact the Department of Immigration and Citizenship (DIAC) on 13 18 81 or visit www.immi.gov.au

You’ll also need a Tax File Number (TFN). These are issued by the Australian Taxation Office (ATO) and are used to identify people for tax purposes. To avoid paying the highest rate of tax you should give your employer your TFN. For information phone the ATO on 13 28 61 or visit www.ato.gov.au .
