Counter surveillance is the other side of the work. People come to us because something does not add up. A former partner who knows things they should not know. A competitor who seems to anticipate every move. A vehicle that turns up in the same mirror too often. Sometimes there is a device. Sometimes the explanation is simpler and no less serious.
We provide counter surveillance in Darwin and throughout the Northern Territory, for private clients, law firms, insurers and employers.
How we run counter surveillance in Darwin
A sweep covers radio frequency detection, physical inspection of the likely concealment points, and examination of vehicles for tracking devices. Physical inspection matters as much as the electronics, because a great many devices found in real premises are not transmitting when the sweep happens. We also look at the non technical explanations, since shared accounts, retained access and family locator apps account for more apparent surveillance than hidden cameras do.
What the Northern Territory law means for this work
The Territory licenses investigators through agent legislation, not security legislation. The relevant statute is the Commercial and Private Agents Licensing Act 1979, administered by NT Consumer Affairs, and the category is an inquiry agent licence. The separate Private Security Act 1995 covers security officers and crowd controllers and does not cover investigators, so a private security licence is the wrong authority for this work.
Section 11 is where the Territory differs sharply from most of the country. The offence applies to a person who is not a party to the private conversation. Unlike Tasmania and the ACT, the Territory does not criminalise a party recording their own conversation, which comes up constantly in Territory matters.
Section 12 of the Surveillance Devices Act 2007 prohibits monitoring, visually recording or observing a private activity you are not a party to where consent has not been given. The exceptions are confined largely to warrants, emergency authorisations and law enforcement duty use. There is no general protection of lawful interests exception for covert optical surveillance of a private activity in the Territory, which makes it stricter than several larger states.
Section 13 prohibits determining the location of a person or thing without the express or implied consent of the person, or of the owner or person in control. Covert vehicle tracking in the Northern Territory is an offence, and there is no investigator exception.
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 NT 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 NT law and contains no exemption for private investigators.

What you receive
You receive a written record of what was examined, what was found, and where. If a device is located we advise on preservation rather than removal, because the device itself is evidence and pulling it out of the wall tells whoever placed it that you know.
Where we work in the Northern Territory
Greater Darwin is a three council conurbation spread over roughly forty kilometres, and treating it as one compact city leads to bad planning. The City of Darwin covers the CBD, Larrakeyah, Stuart Park, Parap, Fannie Bay, Nightcliff, Rapid Creek, Alawa, Casuarina, Tiwi, Leanyer, Malak and Karama. Palmerston, twenty five kilometres south east, covers Gray, Moulden, Woodroffe, Driver, Durack, Farrar, Rosebery, Bakewell and Zuccoli. The Litchfield rural area covers Howard Springs, Humpty Doo, Virginia, Coolalinga, Berry Springs and Noonamah, where large rural blocks make access materially harder. Beyond Darwin we work Katherine, Tennant Creek, Alice Springs and Nhulunbuy. The wet season, roughly November to April, closes unsealed roads and floods crossings in the Top End, and access to Aboriginal land generally requires a permit from the relevant Land Council.
Where the evidence ends up
- Local Court of the Northern Territory. Civil claims from $25,000 to $250,000, domestic violence orders, summary offences and less serious indictable matters. The Local Court sits without juries.
- Supreme Court of the Northern Territory. Civil above $250,000 and serious indictable crime, with registries at Darwin and Alice Springs.
- Work Health Court. Workers compensation under the Return to Work Act, the primary destination for factual and surveillance evidence in Territory compensation claims.
- NTCAT. Civil claims under $25,000, tenancy, guardianship and review of licensing decisions.
- Federal Circuit and Family Court of Australia. Family law is federal, so a family matter runs under Commonwealth law even though the conduct investigated is governed by NT rules.
Frequently asked questions
What do I do if I think I am being monitored right now?
Do not discuss it in the space you are worried about, and do not start searching, because both alert whoever is responsible. Contact us from a different location. If you are in a family violence situation, please also speak to a specialist support service, as there are safety considerations beyond the technical question.
Can you tell me who placed a device?
Sometimes. Devices carry SIM cards, purchase trails and configuration details that can be traced. It is not guaranteed, and we would rather set that expectation before a sweep than after it.
Do you cover regional the Northern Territory as well as Darwin?
Yes. Darwin 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.
Talk to us about a NT matter
Every enquiry starts with a confidential conversation about what you actually need, and sometimes that conversation ends with us saying an investigation is not warranted. Call 1300 792 283 or get in touch for a free consultation and a written quote before any work begins.
