These enquiries almost always come from a family member, and they are rarely really about proof. Someone has watched money disappear, or watched a person change, and needs to know whether what they suspect is happening is actually happening before they act on it.
We provide addiction investigations in Adelaide and throughout South Australia, for private clients, law firms, insurers and employers.
How we run addiction investigations in Adelaide
The work is discreet observation of patterns rather than confrontation. Where money is going, where time is being spent, whether stated activity matches actual activity. We keep the scope to what is needed for the decision you are facing, whether that is a family conversation, a family law matter, a workplace safety issue or a financial protection step.
What South Australia law means for this work
South Australia licenses investigators under the Security and Investigation Industry Act 1995, administered by Consumer and Business Services rather than by police. Section 6 creates an investigation agent’s licence, and it comes in two categories: restricted to inquiry work, or restricted to collection work. Only the inquiry work category covers investigation. Licences are renewed every twelve months, and licensing appeals go to the Administrative and Disciplinary Division of the District Court rather than to the state tribunal.
South Australia is the only jurisdiction with an express exception for licensed investigators. Section 5(4)(a)(iv) of the Surveillance Devices Act 2016 disapplies the optical surveillance prohibition where the device is used by the holder of an investigation agent’s licence authorising inquiry work, in the course of their functions, and where the use is reasonably necessary for the protection of a person’s lawful interests. Every element of that matters. It does not help an unlicensed operator, a collection only licence, or a client acting on curiosity.
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 SA 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 SA law and contains no exemption for private investigators.

What you receive
You receive a factual record of what was observed, which is what allows a family to move from suspicion to a conversation grounded in something. Where the pattern does not support the concern, we report that with equal clarity, and that outcome is more common than people expect.
Where we work in South Australia
Metropolitan Adelaide breaks into the CBD and inner ring through Adelaide, North Adelaide, Norwood, Unley and Prospect, the north through Salisbury, Playford, Elizabeth and Gawler, the north east through Tea Tree Gully, Campbelltown and Modbury, the eastern foothills through Burnside, Mitcham and Stirling, the west through Charles Sturt, West Torrens, Port Adelaide and Semaphore, and the south through Marion, Holdfast Bay, Onkaparinga, Noarlunga and Aldinga. Beyond the city we cover the Adelaide Hills, the Barossa, the Fleurieu and Kangaroo Island, the Limestone Coast, the Murray and Mallee, Yorke and Mid North, Eyre and Western, and the Far North.
Where the evidence ends up
- Magistrates Court of South Australia. Summary crime and smaller civil claims, with country registries at Berri, Mount Gambier, Murray Bridge, Port Augusta, Port Lincoln, Port Pirie and Whyalla.
- District Court of South Australia. Mid tier criminal and civil work, including the Administrative and Disciplinary Division.
- Supreme Court of South Australia. The highest state court, including the Court of Appeal.
- SACAT. Tenancy, guardianship, mental health and review of government decisions.
- South Australian Employment Tribunal. Workers compensation under the Return to Work Act 2014, the main forum for insurer commissioned evidence here.
- 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 SA rules.
Frequently asked questions
What if I am wrong?
Then you will know that, and it is a good outcome. A meaningful share of these enquiries end with the concern not being borne out, and being able to set a suspicion down is worth as much as confirming it.
Is this an appropriate use of an investigator?
Where there is a real financial, safety or legal decision resting on it, yes. Where the underlying issue is a relationship or a health concern, an investigator is not the right first call, and we will say so rather than take the work.
Do you cover regional South Australia as well as Adelaide?
Yes. Adelaide 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 SA 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.
