These are Proof of Record Ownership (PORO) questions. They’re based on non-public data from the ABR to verify that you’re authorised to register the business.
To prepare:
Log into the ABR and review your organisation’s registration details.
Make sure you know things like:
The date your ABN was registered
Past business names or addresses
GST registration status and dates
If you answer the PORO questions incorrectly too many times, your access may be locked and you’ll need to call PRODA support.
