Recording Phone Calls in South Australia: What the Law Requires

Recording your own phone call in South Australia is governed by state law, not the federal wiretapping statute most people assume applies. Section 4 of the Surveillance Devices Act 2016 (SA) requires the consent of everyone on the call, a lawful-interests justification, or the state's public-interest exception, before you can lawfully record a conversation you are part of.

Can You Record Your Own Phone Call in South Australia?

Only with consent, a lawful interest, or the public interest, the same three routes that apply to any other private conversation in South Australia. Section 4(1)(b) of the Surveillance Devices Act 2016 (SA) prohibits recording a private conversation you are a party to, and a phone call ordinarily meets the Act's definition of a private conversation. Unless every principal party consents, the recording must be reasonably necessary to protect your own lawful interests under s.4(2)(a)(ii), or fall within the separate public-interest exception at s.6, to be lawful.

Jurisdiction scope: This article addresses phone call recording law in South Australia under the Surveillance Devices Act 2016 (SA) and the federal Telecommunications (Interception and Access) Act 1979 (Cth). It does not address the phone recording rules of other Australian states or territories; for a national comparison, see recording a phone call in Australia. For South Australia's general recording rules, see South Australia recording laws.

The Federal Layer: Why the TIA Act Usually Doesn't Apply to Your Own Call

The Telecommunications (Interception and Access) Act 1979 (Cth) makes it a serious federal offence to intercept a communication passing over a telecommunications system. Section 7 of that Act prohibits interception, and interception is defined around listening to or recording a communication in its passage over the system, without the knowledge of the person making it. A participant on a call has knowledge of their own communication, and recording at the handset happens at the point of receipt, not while the call is in transit across the network. That distinction matters: it is generally the state Act, not the federal TIA Act, that governs whether you can record your own phone call. The federal Act becomes the operative framework when someone other than a party to the call taps the line itself, for example intercepting a call in transit over the network, which is a different and more serious kind of conduct addressed elsewhere in the TIA Act.

The State Layer: Section 4 of the Surveillance Devices Act 2016 (SA)

Once the TIA Act is set aside, South Australia's own Act governs. Section 4(1) prohibits both listening to a conversation you are not part of and recording one you are part of. For your own call, the exceptions in s.4(2) apply: consent of every party, express or impliedly given, or the lawful-interests exception in s.4(2)(a)(ii), which excuses a recording that is reasonably necessary to protect your own lawful interests. Courts have accepted a lawful interest where a person had a genuine, objectively assessable safety concern, for example receiving calls in breach of an intervention order: Groom v Police [2015] SASC 101 (decided under the predecessor Act, on materially similar wording). Courts have rejected a lawful interest where the recording was made simply to gain an advantage in a dispute, or as a general precaution with no specific threat behind it.

South Australia's separate public-interest exception at s.6 is not limited to a participant protecting their own interest. It can excuse a recording, by a party to the call or a non-party, where the use of the device is genuinely in the public interest, though the Act does not define that term beyond the general concept of exposing serious wrongdoing or addressing a genuine threat to public safety.

Notifying the Other Person: What Counts as Consent

Consent under s.4(2)(a)(i) can be express or implied. Express consent means the other party clearly agrees, in words, to being recorded. Implied consent arises where a person was genuinely aware that recording was occurring and chose to continue the call regardless.

For personal calls: tell the other person plainly, at the start of the call, that you intend to record it, and get their agreement before you proceed. Continuing the call after being told is usually treated as implied consent, but a clear verbal confirmation is the safer practice given the criminal penalties involved.

For businesses recording customer calls: an automated message stating that the call is being recorded, played before the customer discusses their matter, is the standard approach. If the customer continues after hearing the notice, that generally establishes implied consent under s.4(2)(a)(i). If a customer objects, the recording should stop.

Sharing a Recorded Call Is a Separate Offence

Making a lawful recording of a phone call does not automatically mean you can share it. The Act treats publication as a distinct offence, and which section applies depends on which exception justified the original recording. Section 9 governs material obtained under the lawful-interests exception: it may be shared only to a party to the call, with everyone's consent, to an investigating agency, in specified proceedings, or to a media organisation, with a maximum penalty of $10,000 for an individual and $50,000 for a corporation, no imprisonment component. Section 10 governs material obtained under the public-interest exception and generally requires a judge's order before publication, unless disclosed to or by a media organisation, at the same maximum penalty. A person who lawfully records a threatening call under the lawful-interests exception and then forwards the audio to a friend or posts it online, without meeting one of the s.9 grounds, commits a fresh offence even though the original recording broke no law.

Publishing or Sharing Recorded Calls: The Doxxing Overlay

Since 11 December 2024, the Criminal Code (Cth) has included doxxing offences at sections 474.17C and 474.17D, targeting the use of a carriage service to publish someone's personal data in a way reasonable persons would regard as menacing or harassing. Where sharing a recorded call also involves publishing the other party's personal information in a menacing or harassing way, this federal offence can apply on top of South Australia's own publication restrictions under ss.9, 10 and 12.

Cross-Border and Interstate Calls

If you are calling someone interstate, your own conduct in South Australia is still governed by South Australian law, and the other party's conduct is governed by the law of wherever they are. A South Australian resident cannot rely on a more permissive rule that might apply to the other party in, for example, Victoria or Queensland. The safest approach for a call involving a South Australian participant is to assume South Australia's narrower rule applies to that end of the conversation.
