Custody matters are the hardest work we do, and the ones where the temptation to overreach is strongest. A parent who is genuinely worried about a child will consider things they would never otherwise consider. Part of our job is to be the person in the room who says which of those things would destroy their case.
We provide child custody investigations in Darwin and throughout the Northern Territory, for private clients, law firms, insurers and employers.
How we run child custody investigations in Darwin
We establish what is actually observable and relevant to a child’s welfare, which is a narrower category than most parents expect. Supervision arrangements, who is present during care time, the condition of a home, whether stated arrangements match actual ones. We work lawfully and from public vantage points, and we do not gather material about a former partner that has nothing to do with the child, because a court will notice and it will count against the parent who commissioned it.
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 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 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.
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 factual record suitable for a family lawyer to work with. Family law is federal, so the proceeding runs under the Family Law Act 1975 in the Federal Circuit and Family Court of Australia, but the conduct being investigated is governed by the surveillance law of the state or territory it happens in. Both have to be right.
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
Will evidence like this help my case?
Sometimes substantially, sometimes not at all. Courts in family matters are concerned with the child, not with proving a former partner is a bad person. Evidence that goes to a child’s welfare and safety carries weight. Evidence gathered to settle a score tends to reflect badly on the parent who gathered it.
Can I record my child’s other parent?
This is jurisdiction specific and it is the question we are asked most often. The rules on recording a conversation you are party to differ across Australia, and the rules on then using that recording differ again. Ask before you record, not after.
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.
