Private Investigator Surveillance Services Australia
Discreet. Documented. Decisive. When you need answers, our licensed investigators deliver irrefutable evidence - professionally and confidentially.
When suspicion alone isn't enough, surveillance provides the factual evidence you need to move forward with confidence. Stirling Investigations conducts covert surveillance operations for individuals, families, and businesses across New South Wales, using military-grade techniques refined over years of active service.
Our licensed investigators use high-resolution cameras, real-time tracking, and advanced observation methods to document the movements and activities of your subject - whether that's a suspected unfaithful partner, an employee making fraudulent claims, or an individual whose behaviour has placed others at risk. Every surveillance operation is conducted lawfully and ethically within Australian privacy legislation.
You receive a comprehensive evidence report with timestamped photo and video documentation - clear, organised, and ready for use in whatever decisions lie ahead. We provide daily updates throughout, so you're never left wondering what's happening.

Book Your Free ConsultationYes. Licensed private investigators in Australia can legally conduct surveillance of individuals in public places. We operate strictly within the Surveillance Devices Act and relevant state privacy legislation. We will advise you upfront if any aspect of your request falls outside legal boundaries.
This varies significantly by objective. A straightforward activity check may take 4--8 hours. An infidelity investigation or workers comp case may require multiple days across different locations. We'll advise the most efficient approach during your consultation.
No. All surveillance is conducted covertly by experienced investigators trained in counter-surveillance. We use unmarked vehicles, plain-clothes operatives, and position changes to avoid detection.
Depending on your selected package, you'll receive timestamped photographs, written narrative report, and/or video footage. All evidence is professionally documented with time, date, and location metadata.
Evidence gathered during lawful surveillance can be used in civil, family, and employment tribunal proceedings. We document everything to meet evidentiary standards. Note: infidelity evidence alone cannot be used in Australian divorce proceedings - but it can inform custody, financial settlements, and personal decisions.
We can only observe and document. If the subject does not engage in the activity you're concerned about during our deployment, we report that accurately. We'll advise whether continued surveillance is likely to yield results.

A Sydney law firm called us after a senior executive who'd resigned three months earlier, citing a "career break", was spotted having lunch with executives from a direct competitor. Under her employment contract, a 12-month non-compete restraint was in place prohibiting her from working for a competitor or approaching the firm's clients. The firm needed proof before their commercial lawyers could act.
Over five working days we deployed agents across three locations: the competitor's Sydney CBD office, a co-working space she was rumoured to be using, and a series of client meetings we had independent knowledge of. Plain clothes, unmarked vehicles, careful distance. By day three we had documented her entering the competitor's building at 8:15 each morning and leaving at close of business. We photographed her in two separate café meetings near the CBD, meetings the firm subsequently confirmed were with their two largest clients. On day four, we observed her being escorted through the competitor's office by one of their senior partners. On day five, we captured her walking out of the building carrying branded materials, a detail that later proved crucial.
Our evidence package including a photographic timeline, written investigator report, and secure video footage, was delivered to the instructing lawyers within 48 hours of the final deployment. They used it to obtain an urgent interlocutory injunction. A settlement was reached within two months, including the return of confidential materials and a costs order in the client's favour. She never knew she'd been observed.
