What is the Tourist Refund Scheme (TRS)?
Tax for Travellers (PDF 1.1Mb) - Government publication explaining the Tourist Refund Scheme (TRS)
The TRS enables you to claim a refund of the goods and services tax (GST) that you pay on goods bought in Australia. The refund only applies to goods you take as hand luggage when you leave the country. However, unlike other tourist shopping schemes, you can use the goods before leaving Australia.
The GST refund is the amount of GST shown on the purchase invoice. Customs will calculate your refund for you. The TRS is open to all overseas visitors and Australian residents, except air and sea operating crew.
How does the scheme work?
The refund will be paid on goods costing $300 (GST inclusive) or more, bought from the same store, no more than 30 days before you leave. You may purchase several lower-priced items from the one store, either at the one time or over several occasions within the 30-day period, provide the total purchase amounts to $300 (GST inclusive) or more and the goods are covered by the one time tax invoice. If you are leaving Australia through an international airport, you may collect your refund in cash on departure (if the refund is $200 or less) or choose a non-cash option.
