How-to-vote cards

Part 6 of the Electoral Regulations.

How-to-vote cards must comply with authorisation requirements and must not mislead voters. They should clearly indicate the candidate or party issuing the card and follow the official ballot format.

Broadcast media authorisations

Section 112 of the Electoral Act and the 'Guidelines for the broadcast of political matter' (ACMA).

  • Radio advertisements must include a spoken authorisation at the end of the advertisement. This format requirement is governed by federal broadcasting regulations, including the Broadcasting Services Act 1992 and ACMA guidelines.
  • Television advertisements must include both a spoken and a text-based authorisation at the end of the advertisement. Also governed by federal broadcasting regulations.

While section 112 of the Electoral Act outlines the content of the authorisation (i.e., what must be included), the formatting requirements for broadcast media are set by federal law and apply nationally, including in South Australia.

Digital advertising

Online and social media advertising must comply with authorisation requirements. Paid digital ads may be subject to additional disclosure obligations under the Electoral Act.

Artificial intelligence in electoral advertising

Under sections 115B to 115D of the Electoral Act, it is prohibited to publish or distribute electoral advertising generated by artificial intelligence that falsely depicts a person performing acts they did not do.

Penalty: Up to $10,000 for breaches.

Consent exception: Allowed only if the person depicted has given written consent and the advertisement is clearly labelled as AI-generated.

The Electoral Commissioner may order removal of such ads and require corrective statements.
