If you intend to work in Australia, you may have to apply the TFN(Tax File Number) first. Anybody who works in AUS must have a TFN in order to pay taxes, and everybody who works has to pay taxes, otherwise it is illegal. To apply the TFN, you can apply it from online and there will be no charges for applying this. The number will be received within two weeks. If you have not received in two weeks, you have to contact the Tax Office. Here is the Australian Tax Office website link:
