Servicing Adelaide and South Australia
Magnum Investigations operates across the greater Adelaide metropolitan area and regional South Australia. While we do not run a public walk-in office, our investigators work on the ground throughout SA, including the Adelaide CBD, Norwood, Unley, Burnside, Prospect, Salisbury, Port Adelaide, Morphett Vale, Mount Barker and Gawler, as well as the Barossa Valley and Fleurieu Peninsula corridors. Engagements are arranged remotely and conducted wherever the matter requires, so there is no need to attend an office to get started.
Licensed and Lawful Investigations in South Australia
Private investigation in South Australia is regulated. Under the Security and Investigation Agents Act 1995 (SA), administered by Consumer and Business Services, investigators must be licensed, and unlicensed investigation work is a criminal offence. Licensed investigators also operate within strict limits: they cannot intercept telecommunications, access private records unlawfully or trespass on private property. Engaging a licensed investigator protects you, because evidence gathered lawfully is the evidence that holds up if your matter reaches a court, tribunal or insurer.
Private Investigator Costs in Adelaide
The cost of a private investigator in Adelaide depends on the type of matter, the hours required and the complexity of the work. Surveillance is generally charged at an hourly rate, while services such as background checks, skip tracing and process serving are often quoted as a fixed fee per task. The main factors that affect cost are the number of investigators needed, travel and time on the ground, the level of reporting required, and how quickly you need results.
