Hi there! I understand you're having trouble scanning your passport with the Australian ETA app. To help you better, can you tell me more about what happens when you try to scan it? For example, do you get any error messages, or does the scan just not register anything?

Meanwhile, here are some initial tips that often solve passport scanning issues:

1. Make sure your device’s camera lens is clean and that there’s good lighting when scanning the passport’s photo page. Avoid glare or shadows on the passport.

2. If the app uses NFC (a chip scan) rather than photo scanning, ensure your device supports NFC reading and that your phone’s NFC is turned on. Also, place the phone's NFC reader directly on the passport’s chip (usually embedded on the identity page).

3. Remove any phone case that might interfere with the scanning process.

4. Try to keep the passport steady and scan from an angle that the app suggests—sometimes moving the phone slowly up and down helps it read the details.

5. Check if your Australian ETA app is up to date and install any updates if available.

Could you also confirm if you are scanning the passport’s photo or trying to read the chip with NFC? This will help me guide you through the right steps.

If the problem persists after these checks, I can walk you through more advanced troubleshooting or alternative manual input options. Let me know!
