Understanding CTP Insurer Surveillance in NSW

In New South Wales, compulsory third party (CTP) insurers may use surveillance to assess the credibility of injury claims following a motor accident. This practice is not uncommon in Greater Sydney, where claims are frequent and insurers routinely review claimant activities to verify reported injuries. Surveillance may involve video or photographic monitoring of a claimant’s daily movements, physical abilities or social behaviour, particularly if there is a discrepancy between the claimed injury and observed activity.

Insurers do not use surveillance to determine fault in a motor accident. Liability for the accident itself is established through police reports, witness statements, and accident scene evidence. Surveillance is used instead to assess the nature, severity and ongoing impact of injuries claimed under the CTP scheme. The Motor Accident Injuries Act 2017 (MAIA) governs all CTP claims in NSW, including the use of surveillance as part of a claim assessment process.

How Insurers Use Surveillance to Assess Liability

Surveillance investigations are conducted to verify whether a claimant’s reported injuries are consistent with their observed physical capacity and daily activities. Insurers may engage private investigators or use digital monitoring tools to record claimants over a period of time, often in public spaces across Greater Sydney such as shopping centres, parks, or residential areas.

The insurer’s goal is not to prove fault but to assess whether the claimant’s functional limitations are genuine and ongoing. For example, if a claimant reports a back injury that limits lifting, but surveillance shows them carrying heavy shopping bags or lifting furniture, the insurer may question the severity or persistence of the injury. This information may be used to challenge the need for ongoing treatment and care benefits, weekly income payments, or to assess the validity of a damages claim.

Surveillance is not used to determine whether an accident occurred or who was at fault. That determination is made independently through accident documentation and, where necessary, a review by the Motor Accident Commission (MAC). Surveillance is a tool for assessing the credibility of injury claims, not the legal liability for the accident.

What Factors Insurers Consider During Surveillance

When reviewing surveillance footage, CTP insurers consider several factors to assess injury claims. These include:

  • The claimant’s physical movements and posture during observed activities
  • Whether the claimant performs tasks that contradict reported limitations (e.g., climbing stairs, lifting objects, driving)
  • The consistency of observed behaviour with medical reports and treatment progress
  • The timing and context of the surveillance (e.g., whether it occurred during a period of reported recovery or ongoing disability)

Insurers may compare surveillance findings with medical evidence, including reports from treating practitioners, imaging results, and assessments of whole person impairment (WPI). If surveillance shows a claimant engaging in activities that would normally be restricted by a reported injury, the insurer may seek to reduce or discontinue benefits, or challenge the claim for damages.

A claimant’s ability to perform certain movements in a video does not automatically invalidate a medical diagnosis. The insurer must still demonstrate that the injury claim is inconsistent with objective medical findings and that the observed activity exceeds reasonable functional capacity.

Legal Protections and Limitations on Surveillance

Surveillance in NSW is subject to legal and ethical boundaries. Insurers must not use surveillance to harass, intimidate, or invade privacy in a way that breaches the law. The use of surveillance must be proportionate, relevant to the claim, and conducted in a manner that respects privacy rights.

Under the MAIA, claimants have the right to be informed if surveillance is being conducted, and to request access to the footage. Insurers are not required to notify claimants in advance, but they must not use surveillance in a way that constitutes a breach of privacy, such as recording inside a private residence or in a private medical setting.

If a claimant believes surveillance was conducted improperly, such as in a private location, without reasonable justification, or in a way that causes distress, they may raise a complaint with the Motor Accident Commission or seek legal advice. The use of surveillance must not be used to undermine a claim without a reasonable basis.

How Claimants Can Respond to Surveillance Findings

If a claimant receives notice that surveillance has been conducted, they should not assume that the findings will automatically affect their claim. The first step is to review the surveillance material, if made available, and compare it with medical records and treatment notes.

Claimants may respond by:

  • Explaining any apparent inconsistencies (e.g., carrying a bag while using a back support, or walking with a limp but not using a walking aid)
  • Providing context for the observed activity (e.g., the activity occurred during a temporary pain relief period, or was performed with assistance)
  • Submitting a written statement or medical report clarifying functional capacity and limitations
  • Requesting a review of the surveillance findings by an independent medical assessor

It is not uncommon for claimants to perform tasks in a limited way during surveillance, such as walking short distances or standing briefly, without fully replicating their usual daily function. These observations should be interpreted in context, not in isolation.

If the insurer uses surveillance to reduce or deny benefits, the claimant may request a review under the CTP scheme. Dispute resolution options are available through SIRA, including mediation and, if necessary, an application to the NSW Civil and Administrative Tribunal (NCAT).

When to Seek Independent Legal Advice

Surveillance investigations can be stressful and may lead to disputes over claim entitlements. The legal and procedural aspects of responding to surveillance findings are complex and vary depending on the nature of the injury, the claimant’s medical history, and the timing of the accident.

A claimant should consider seeking independent legal advice if:

  • Surveillance footage is used to reduce or stop weekly income payments or treatment and care benefits
  • The insurer challenges the claim for damages based on surveillance
  • There is a dispute over the credibility of injury claims
  • The claimant believes surveillance was conducted in a way that breaches privacy or is otherwise improper

Legal advice can help clarify rights under the MAIA, assess the strength of evidence, and determine whether a formal dispute or review is warranted.

Practical Steps for Claimants in Greater Sydney

If you have been involved in a motor accident in Greater Sydney and believe you may be subject to surveillance, take the following steps:

  • Preserve all medical records, treatment notes, and correspondence with your insurer
  • Keep a record of your daily activities, including any limitations or pain episodes
  • Do not alter your behaviour in response to surveillance, act as you normally would
  • If you are informed of surveillance, request a copy of the footage and seek advice before responding
  • Contact SIRA or a legal adviser if you believe the surveillance was conducted improperly
