Workers’ compensation investigations

An insurer, self-insurer, employer or legal adviser may need to understand a reported incident, the handling of a concern or a disputed sequence of workplace events. The brief identifies the decisions the evidence will inform and the questions requiring investigation. It also establishes the authorised instructing person, reporting audience and relevant jurisdiction.

A claim enquiry can be commissioned as a connected investigation or a contained task, such as a witness package, records review or chronology. The scope should explain what is already known, which matters remain disputed and what the required deliverable needs to address.

Physical injury enquiries may address the reported event, work activities, location, available incident records and reporting sequence. Psychological injury enquiries may examine workplace interactions, workload concerns, management actions and how issues were raised or handled. Both call for a careful distinction between the reported account and material that supports it.

The factual investigation does not assess a diagnosis, determine medical causation or decide entitlement. A concern about an account is an issue to examine. The instruction does not begin with a conclusion that a claim is fraudulent.

Interviews establish the witness’s role, opportunity to observe and source of knowledge. Personal observation, information received from others, assumptions and opinion remain distinct. A document may assist recollection without becoming the witness’s independent memory. Approximate dates remain approximate, and differences between accounts are recorded and tested.

Statements are returned for review and correction. Relevant records are identified and linked as annexures where appropriate, with review and signing status recorded. A draft account is not presented as an executed statement. The chronology then connects each material event with its supporting source.

The report addresses the commissioned questions and explains what the available evidence supports. It separates factual findings, allegations, competing accounts and investigator analysis. References allow the instructing team to follow the basis of a proposition, including where an incomplete screenshot or missing original limits what can be established.

The agreed handover may include an executive assessment, scope and methodology, material reviewed, chronology, statements and annexures, an evidence schedule, analysis and limitations. A briefing can address unresolved questions and proportionate further enquiries. Claims decisions remain with the authorised decision-maker.

A new account, missing record or material inconsistency can change the enquiry required. Additional statements, attendance or surveillance need a defined evidentiary purpose and agreed scope. Timing, availability, authority and commercial implications are considered before the assignment expands.

CTP and public liability matters are separate insurance instructions. Their incident, witness, scene and record enquiries can also be discussed through the insurance and claims pathway. They are not treated as workers’ compensation claims or silently absorbed into this practice.
