How to verify the identity of a signer using Australia Post Digital iD?

Australia Post Digital iD is a government-backed digital identity verification service in Australia that enables secure authentication of individuals. In eSignature workflows, it verifies the signer's identity by linking their personal details to trusted government records, such as passports or driver's licenses, ensuring compliance with electronic transaction laws like the Electronic Transactions Act 1999 (Cth).
