Electronic Signatures under ETA 1999 in Australian Healthcare

Are Electronic Signatures Legally Binding for Medicare?

Yes. Services Australia accepts electronic signatures for Medicare Assignment of Benefit (AoB) consent, provided they comply with the Electronic Transactions Act 1999 (ETA 1999). This legislation sets out clear conditions that must be met for an electronic signature to carry the same legal weight as a physical ink signature on paper.

The Three Pillars of a Valid E-Signature

For an electronic signature to be compliant under ETA 1999 in a healthcare context, it must meet three core requirements:

• Identity: The method used must identify the person signing and indicate their approval of the information contained in the document. GPConsent captures the signor's name, email, IP address, and their relationship to the patient if they are a representative.
• Reliability: The method must be as reliable as appropriate for the purpose for which the electronic communication was generated. This means using secure, tamper-evident logs and timestamping the signature transaction.
• Consent: The person to whom the signature is given must consent to the method. In this case, the patient or representative must agree to complete the form electronically, which is handled via a simple checkbox consent flow in the app.

Why SMS Verification Adds Extra Compliance

When sending a consent form to a remote representative (such as a relative of a resident who lacks capacity), validating their identity is crucial. GPConsent uses secure SMS links to deliver forms to the representative's mobile number. When they sign, the transaction log records the mobile number, network details, and timestamp, establishing a robust, audit-proof chain of custody.
