The Guarantor Requirement
A uniquely Australian rule — one photo must be endorsed by a guarantor.
Unlike most countries, Australia requires one of your two identical printed photos to be signed on the back by an eligible guarantor — someone who has known you for at least a year and belongs to an approved occupation category (this isn't required for the photo itself, but it's an essential part of a complete application).
This tool handles the photo cropping and compliance — the guarantor endorsement is a separate step you'll complete after printing.
