The ATO considers that most people who come to Australia on a temporary working visa or visit are generally not considered Australian tax residents.
This is because, consistent with their visa requirements, it is not the intention to stay in Australia, but only intend to have a holiday while working some of the time.
Should you travel to Australia as a working holiday maker either on a 417 (working holiday) or a 462 (work & holiday) visa, the first $45,000 of your income is taxed at 15% and the balance is taxed at ordinary rates. This is regardless of residency status.
As a foreign tax resident working in Australia you are still required to lodge an Australian Tax Return with the Australian Taxation Office (ATO) to report your Australian sourced income.
