How can I claim the tax back when leaving Australia?Updated 6 months ago

Provided that your piece is being taken out of Australia within 60 days of the purchase date (or final payment date) you may be eligible to claim a refund of the GST paid on your piece, through the Tourist Refund Scheme. This must be processed by the original purchaser at the airport upon departure from Australia.
