The Tourist Refund Scheme (TRS) enables you to claim a tax refund on goods purchased in Australia. The Tourist Refund Scheme office is operated by the Australian Customs and Border Protection Service and is located on the Departures Level just after Customs within the main SYD Airport Tax & Duty Free store.
To claim a refund you must:
Spend $300 or more (including GST) in a single store
Buy goods no more than 60 days before departure
Wear or carry the goods on board and present them along with your tax invoice, passport and boarding pass to a TRS facility
Claims are only available up to 30 minutes prior to the scheduled departure of your flight
