Perth Suburbs and Regional WA Coverage

Our investigators operate across the entire Perth metropolitan area, including the CBD, Fremantle, Joondalup, Rockingham, Mandurah, Midland, Armadale, Baldivis, and the northern and southern coastal corridors. We also take on assignments in regional WA — Bunbury, Geraldton, Kalgoorlie, Albany, and Broome — as well as fly-in fly-out (FIFO) workforce investigations at mine sites and remote industrial facilities.

If your matter is outside Perth metro, call us to discuss logistics. We have the network and the experience to cover WA's geography.

Licensed Investigators Under WA Law

Private investigators operating in Western Australia must hold a licence issued under the Security and Related Activities (Control) Act 1996 (WA). Licences are administered by WA Police Force Licensing Services (Security).

All Magnum investigators working in Perth hold current WA licences. When you engage us, you receive a licensed, insured professional — not a freelancer operating outside the regulatory framework. This matters particularly if evidence gathered during an investigation is to be used in legal proceedings.

Private Investigator Perth Cost — What to Expect

Private investigation costs in Perth vary depending on the type and complexity of the work. Surveillance operations are typically quoted by the hour and may involve multiple investigators for mobile surveillance. Background checks and person traces are usually quoted as a fixed fee per report.

Rather than publish rates that may not reflect your specific situation, we provide a free, no-obligation phone assessment. During that call we will give you an honest estimate based on the scope of your matter. We are transparent about costs upfront — you will know what you are committing to before any work begins.

Frequently Asked Questions — Private Investigators Perth

Do private investigators in Perth need a licence?

Yes. Under the Security and Related Activities (Control) Act 1996 (WA), anyone acting as a private investigator in Western Australia must hold a current investigator's licence issued by WA Police Force Licensing Services (Security). Engaging an unlicensed operator puts you at risk and may render any evidence inadmissible.

What areas does Magnum cover in Perth?

We cover the full Perth metropolitan area and regional WA. This includes suburbs from Two Rocks in the north to Mandurah in the south, as well as regional centres such as Bunbury, Geraldton, Kalgoorlie, and Albany. Remote and FIFO assignments can also be arranged.

How long does a surveillance operation in Perth take?

It depends on the nature of the matter. A straightforward activity check may be completed in one or two sessions. More complex matters — such as establishing a pattern of behaviour for court proceedings — typically require multiple days of surveillance. We will advise you on expected duration during your initial consultation.

Can Magnum help with matters going to the Family Court?

Yes. Our investigators are experienced in gathering evidence for Family Court proceedings, including child custody and parenting arrangement matters. Reports are prepared to a standard suitable for use as evidence.

Is everything kept confidential?

Confidentiality is fundamental to our operation. We do not discuss client matters with third parties and our investigators operate covertly. You are in control of how and when any findings are used.

How do I get started with a Perth investigation?

Call us on 1300 792 283 or submit an enquiry via our contact page. We will arrange a free, confidential consultation to assess your needs and provide a clear cost estimate before any work begins.
