Understanding Surveillance Laws in Queensland & NSW

If you've ever thought about hiring a private investigator, or even just installing a hidden camera to find out what's really going on in your business or your relationship, there's a question that should come before anything else. Is what you're about to do actually legal?

It's a fair question, and honestly, most people don't know the answer. Surveillance laws in Australia are genuinely confusing, partly because they differ from state to state, and partly because the rules around things like cameras, listening devices and tracking are scattered across several different pieces of legislation rather than sitting in one neat place. Get it wrong, and you're not just risking a wasted investigation. You could be looking at criminal penalties, evidence that gets thrown out, or even a lawsuit from the person you were trying to investigate in the first place.

Complete Corporate Services has operated as a licensed investigation and surveillance provider across Queensland and New South Wales for close to four decades, so this is genuinely something we live and breathe. This guide breaks down what's actually legal, what isn't, and why working with a properly licensed investigator matters so much more than people realise.

Why This Matters More Than You'd Think

Surveillance touches a surprising number of everyday situations. Maybe you suspect a staff member is rorting a Workcover claim. Maybe you want to know whether your business partner is being honest with you. Maybe you're chasing evidence for an insurance claim, or you simply want to check on an ageing parent's carer. Whatever the reason, the moment you start watching, recording or tracking someone without their knowledge, you've stepped into territory that's regulated by law, and the rules genuinely matter.

Two separate issues are at play here. The first is whether you're even allowed to conduct the surveillance in the first place, which is governed by privacy and surveillance device legislation. The second is whether you're allowed to be the one doing it, which in both Queensland and NSW generally means holding the right licence if you're conducting investigations for reward.

Queensland: The Security Providers Act

In Queensland, the key piece of legislation is the Security Providers Act 1993. Under this Act, a private investigator is someone who, for reward, obtains and gives private information about another person without that person's express consent, or who carries out surveillance for obtaining private information about another person without their express consent. If that's what you're doing, and you're doing it for payment, you legally need to hold a private investigator licence to operate.

This matters enormously, because if an investigation is conducted by someone without the appropriate licence, the validity of the resulting investigation report can be affected. In other words, hire an unlicensed operator, and you might end up with a report that's worthless the moment it's challenged, whether that's by an insurer, in a tribunal, or in court. This is exactly why CCS operates under a proper Corporate Security Firm Class 1 licence and Master Licence in Queensland, ensuring that any evidence gathered actually holds up when it matters.

Beyond the licensing requirement itself, Queensland also has specific privacy protections under the Criminal Code, which makes it an offence to observe or visually record someone in circumstances where they'd reasonably expect privacy, such as in a private place or during a private act, without their consent. This is separate from the investigator licensing requirement and applies more broadly to anyone conducting surveillance, licensed or not.

New South Wales: A More Layered Approach

NSW takes a somewhat more complex approach, with two main pieces of legislation working together. The Surveillance Devices Act 2007 regulates listening devices, optical surveillance devices, tracking devices and data surveillance devices broadly across the state, while the Workplace Surveillance Act 2005 adds specific rules that apply when surveillance is being conducted in an employment context.

Under the Surveillance Devices Act, it's generally an offence to use a listening device to record or monitor a private conversation without the consent of the parties involved, with penalties that can include significant fines or imprisonment for individuals, and even steeper financial penalties for corporations. The Act defines a private conversation fairly broadly, essentially any conversation where the circumstances suggest the parties wanted it to remain between themselves.

Optical surveillance, meaning cameras and recording devices, is treated slightly differently. Installing or using a camera to observe or record an activity becomes an offence specifically when it involves entering premises or a vehicle without consent, or interfering with a vehicle or object without the consent of whoever has lawful control of it. This is why, in practice, a great deal of lawful surveillance work happens in public spaces, or on or from property the investigator has a legitimate right to be on or observe from.

Why the Workplace Adds Another Layer

If the surveillance in question relates to employees, NSW's Workplace Surveillance Act introduces additional requirements specifically because employees have a recognised expectation of privacy even while at work. Generally speaking, overt surveillance, the kind employees know is happening, such as CCTV or computer monitoring, requires proper notice be given in advance, along with clear signage and transparent policies explaining what's being monitored and why.

Covert surveillance of employees, watching them without their knowledge, is far more restricted. In most circumstances, it's prohibited unless authorisation has been obtained through proper legal channels, typically where there's a genuine, reasonable suspicion of unlawful activity by specific employees. This is a significant distinction from general surveillance law, and it's an area where businesses frequently get into trouble by assuming that because they own the workplace, they can monitor staff however they like. They can't, not without following the proper process.

What This Means If You're Considering Hiring an Investigator

The practical upshot of all this is fairly simple, even if the underlying law is complicated. If you're considering surveillance, whether that's for a personal matter, a Workcover concern, an insurance claim, or a workplace investigation, the right move is always to engage someone properly licensed who understands exactly where the legal lines sit in your state.

A properly licensed investigator knows how to gather evidence without crossing into unlawful territory, understands the difference between public and private spaces for the purposes of optical surveillance, knows when consent is genuinely required and when it isn't, and understands the additional layer of rules that apply specifically to workplace surveillance if that's the context you're dealing with. This isn't just about avoiding legal trouble for yourself. It's about making sure that whatever evidence is gathered can actually be used, whether that's before an insurer, in mediation, or in court.

What Happens If You Get It Wrong

The consequences of unlawful surveillance aren't hypothetical. In NSW specifically, breaching the Surveillance Devices Act can result in serious fines and even imprisonment for individuals, with even larger penalties available for corporations found to have breached the Act. Beyond the criminal exposure, there's the simple practical problem that unlawfully gathered evidence is generally inadmissible, meaning the entire exercise, whatever it cost in time and money, was ultimately pointless.

There's also a reputational dimension that businesses sometimes overlook. If a business is found to have engaged in unlawful surveillance of an employee, or even a competitor or business associate, the fallout can extend well beyond the immediate legal penalty, damaging trust with staff, clients and the broader public.

How CCS Operates Within These Rules

This is precisely why CCS places such importance on proper licensing and lawful methodology in everything we do. Operating under a Corporate Security Firm Class 1 licence and Master Licence means our investigators understand exactly where the legal boundaries sit in both Queensland and NSW, and conduct every piece of surveillance work, whether that's verifying a Workcover claim, supporting an insurance investigation, or gathering evidence for a commercial dispute, within those boundaries.

This matters just as much for our clients' protection as it does for the people being investigated. A client who engages CCS doesn't need to worry about whether the evidence gathered on their behalf will hold up, because it's been collected properly from the outset, by people who understand the law and have spent decades applying it correctly.

A Confidential Conversation Comes First

If you're considering engaging an investigator, whether for a personal, commercial, insurance or workplace matter, the smartest first step is simply having a confidential conversation about what you're trying to achieve and what's actually lawful and effective in your situation. CCS assesses every enquiry without obligation, which means you can talk through your circumstances and understand exactly what's possible before committing to anything.
