5 Prohibition on use of listening devices
(1) A person shall not use, or cause to be used, a listening device:
(a) to record or listen to a private conversation to which the person is not a party, or
(b) to record a private conversation to which the person is a party.
(2) Subsection (1) does not apply to:
(a) the use of a listening device pursuant to a warrant granted under Part 4,
(b) the use of a listening device pursuant to an authority granted by or under the Telecommunications (Interception) Act 1979 of the Commonwealth or any other law of the Commonwealth,
(c) the use of a listening device to obtain evidence or information in connection with:
(i) an imminent threat of serious violence to persons or of substantial damage to property, or
(ii) a serious narcotics offence,
if it is necessary to use the device immediately to obtain that evidence or information,
(d) the unintentional hearing of a private conversation by means of a listening device, or
(e) the use of a listening device to record a refusal to consent to the recording of an interview by a member of the police force in connection with the commission of an offence by a person suspected of having committed the offence.
(3) Subsection (1) (b) does not apply to the use of a listening device by a party to a private conversation if:
(a) all of the principal parties to the conversation consent, expressly or impliedly, to the listening device being so used, or
(b) a principal party to the conversation consents to the listening device being so used and:
(i) the recording of the conversation is reasonably necessary for the protection of the lawful interests of that principal party, or
(ii) the recording of the conversation is not made for the purpose of communicating or publishing the conversation, or a report of the conversation, to persons who are not parties to the conversation.
(4) Where a listening device is used in the circumstances referred to in subsection (2) (c) and its use would, but for subsection (2) (c), be contrary to this section, the person who used the device shall:
(a) forthwith cause to be served on the Attorney General or a prescribed officer notice of that fact, and
(b) within 7 days after its use, furnish a report, in writing, to the Attorney General:
(i) containing particulars of the circumstances in which the device was used, and
(ii) without affecting the generality of subparagraph (i), containing the same particulars, and specifying the same matters, as are required by section 19 (1) (b) in relation to the use of a listening device pursuant to a warrant granted under Part 4.
23 Part 4 (ss15-21) provides for the issue of warrants authorising the use of listening devices and related matters. The central provision is s16(1) which states:
16 Warrants authorising use of listening devices
(1) Upon application made by a person that the person suspects or believes:
(a) that a prescribed offence has been, is about to be or is likely to be committed, and
(b) that, for the purpose of an investigation into that offence or of enabling evidence to be obtained of the commission of the offence or the identity of the offender, the use of a listening device is necessary,
an eligible Judge may, if satisfied that there are reasonable grounds for that suspicion or belief, authorise, by warrant, the use of the listening device.
….
(4) A warrant granted by an eligible Judge under this section shall specify:
(a) the prescribed offence in respect of which the warrant is granted …
24 The provisions I have set out show that the use of a listening device pursuant to a warrant requires the applicant to suspect or believe particular information in relation to an identified "prescribed offence"; and to stipulate that offence in the proposed warrant (see also Haddad & Treglia at [59]-[60]).
25 But it does not follow that intercepted information relevant to other offences is rendered inadmissible by implication. In Haddad & Treglia, Spigelman CJ (with whom Newman J and Greg James J agreed) said (at [65]-[67]):
65 In the course of her reasons [in R v Karageorge (1998) 103 A Crim R 157] Simpson J referred to the structure of the legislative scheme of the Listening Devices Act and concluded that it did not prevent the use of evidence obtained for the purpose other than that which actuated the original application. Her Honour said at 181:
"What s13 does is to render inadmissible evidence obtained by the use of listening device in contravention of s5. It does not render inadmissible evidence obtained by the use of a listening device that is authorised by a warrant validly obtained and used under the Australian Federal Police Act , even if the information or evidence obtained is incidental to the purpose for which the warrant was issued and the listening device used. The question is not the nature of the information or evidence obtained, but the purpose for, and the circumstances in which, the listening device was used. That the valid use of a listening device produces evidence of an offence other than that in relation to which it was issued does not make that evidence inadmissible. If the listening device is used pursuant to the warrant authorising its use, then evidence of offences other than that which provided the foundation of the issue of the warrant will not be rendered inadmissible by s13. A simple and obvious example will serve to illustrate the point. If an AFP officer, exercising the rights conferred by a warrant validly issued under the Australian Federal Police Act , for the purpose of obtaining evidence in relation to, for example, a narcotics offence, and properly used for that purpose, incidentally hears an admission of murder, s13 does not preclude the use of that evidence in relation to the murder charge, notwithstanding that that was not the purpose for which, or the suspected offence in relation to which, the warrant was issued. The underlying question is directed to the propriety of the use of the listening device, and not to any collateral benefit or advantage that may accrue by reason of the use of the listening device."
66 I agree with her Honour's approach. …
67 In an analogous area, the common law has long accepted that a police officer executing a warrant may seize goods and evidence reasonably believed to relate to a criminal offence, even though the offence is not that for which the warrant was granted.
