Surveillance is the service people picture when they think of a private investigator, and it is also the one most often done badly. Done properly it is patient, lawful observation that produces a record a court will accept. Done badly it produces a grainy phone video, an alerted subject and a matter that is now harder than it was before anyone got involved.
We provide surveillance in Perth and throughout Western Australia, for private clients, law firms, insurers and employers.
How we run surveillance in Perth
A surveillance job starts with a briefing about what you actually need established, because that determines everything else. We work from public vantage points, plan for the subject’s likely patterns rather than reacting to them, and keep continuity of the record from the first observation to the last. Operatives work in shifts on longer jobs so that the same vehicle and the same face are not sitting in the same street for three days running, which is how subjects notice they are being watched.
What Western Australia law means for this work
Western Australia requires two licences under the Security and Related Activities (Control) Act 1996, administered by WA Police Licensing Services. The business needs an inquiry agent’s licence under section 29 and the individual operative needs an investigator’s licence under section 30. Section 61 requires a licensed operator to carry an identity card and produce it on request to the person receiving the service, so you are entitled to ask on the spot.
Optical surveillance is governed by section 6 of the Surveillance Devices Act 1998, and it bites on recording or observing a private activity you are not a party to. Section 3 defines a private activity as one carried on in circumstances reasonably indicating a party wants it observed only by themselves. Activity in a public place that is not a private activity falls outside the prohibition, which is the practical foundation for surveillance work here.
Section 7 is the strictest tracking provision in the country. A tracking device may not be attached, installed, used or maintained without the express or implied consent of the person, or of the person in possession or control of the object. There is no lawful interests exception and no investigator exception. Covert vehicle tracking in Western Australia is not lawful, and anyone offering it is offering you contaminated evidence.
Section 9 makes it an offence to knowingly publish or communicate a private conversation or a record of a private activity obtained through a listening or optical device, subject to exceptions including consent, legal proceedings and reasonable protection of lawful interests.
None of that is a formality. The rules differ genuinely between Australian jurisdictions, and evidence gathered outside them is frequently inadmissible and can expose the person who gathered it. Working inside the WA framework is what makes the result usable.
The federal statutory tort of serious invasion of privacy, which commenced on 10 June 2025 under Schedule 2 of the Privacy Act 1988, applies on top of WA law and contains no exemption for private investigators.

What you receive
You receive time stamped video and photographic material, a written log of observations, and a report written to be read by a court or an insurer rather than by us. Where nothing of significance was observed, we say so plainly. A surveillance report that finds nothing is a legitimate result and often a useful one.
Where we work in Western Australia
The Perth metropolitan region covers thirty local government areas. Operationally that is the central corridor through Perth, Vincent, Subiaco and South Perth, the western suburbs through Nedlands, Claremont and Cottesloe, the coastal north through Stirling, Joondalup and Wanneroo, the eastern hills through Bayswater, Swan, Kalamunda and Mundaring, the south east through Canning, Gosnells and Armadale, and the south west through Melville, Fremantle, Cockburn, Kwinana and Rockingham, with Mandurah in the Peel region alongside. Beyond Perth we work the South West, Great Southern, Wheatbelt, Mid West, Goldfields and Esperance, Pilbara, Kimberley and Gascoyne regions.
Where the evidence ends up

Frequently asked questions
How long does surveillance take?
It depends entirely on the pattern you are trying to establish. Confirming a single suspected meeting might take one evening. Establishing a pattern of behaviour reliable enough for a court usually takes several sessions across different days. We will give you an honest estimate before you commit and tell you if we think the odds are poor.
Will the subject know?
Not if the job is run properly. The most common cause of a subject becoming aware is an under resourced job where the same operative and vehicle are used repeatedly. That is a budgeting decision as much as a tradecraft one, and we would rather tell you the real cost than run a job that burns itself.
Do you cover regional Western Australia as well as Perth?
Yes. Perth work can generally be mobilised faster and at lower cost. Regional work carries travel time and expense, and we will tell you honestly whether the likely result justifies it before you commit.
