This is the Department of Immigration and Border Protection's Tourist Refund Scheme (TRS) Mobile application (the app).

The app will allow you to enter the information that is required to lodge a TRS claim. The app will save the information to your mobile device, allowing you to edit the claim over multiple sessions.
When you have finished entering your information it will be stored in a QR code on your device. This QR code is your TRS claim code. You must present your TRS claim code to an officer at the TRS counter on your departure from Australia.

If you successfully enter your claim details using this app, processing your claim at the TRS counter when you depart should be faster and you may be able to use a dedicated queue to lodge your TRS claim.
