What happens in a workplace investigation (Australia)

In My Corner · Learn — 7 min read · Updated July 2026

Being told your complaint is going to an investigation can be as nerve-wracking as the original problem. The unknown is a big part of the fear, so let's take the mystery out of it. Here's roughly how a workplace investigation works in Australia, and what you're entitled to.

What the investigation is for

The point is a fair look at what happened and a decision on next steps — not a court case, but a process that should follow procedural fairness: you and the respondent both get to be heard, and the respondent gets to know the allegations and respond. It may be run internally or by an external investigator, especially for serious complaints.

The rough shape

Complaint and response. Your report is put to the respondent, who gets a chance to reply.
Interviews and evidence. The investigator interviews you, the respondent, and witnesses, and gathers documents (your dated log and messages matter here).
Findings. The investigator decides, on the balance of probabilities, what happened.
Outcome. The employer decides on any action. You should be told the outcome, at least in general terms.

Your rights and how to prepare

Procedural fairness. A fair process, a chance to put your case, and an unbiased decision-maker.
Protection from adverse action. Being punished for complaining or taking part can breach the general protections.
A support person. You can usually bring a support person to interviews — take up the offer.
Bring your evidence, organised. A dated timeline, messages, emails and witnesses — clear and chronological beats a shoebox of screenshots.
Get support. You can take advice from your union or an employment lawyer, and lean on people outside work. If it's affecting your health, keep a crisis line within reach.

If you feel the process wasn't fair, or the bullying continues, there are further routes — the stop-bullying application (if still employed), a WHS complaint, general protections, or legal advice. An investigation is a process that owes you fairness, not a verdict waiting to happen.

This article is general information, not legal advice. In Australia the Fair Work Commission can make stop-bullying orders (for people still at work), and strict deadlines apply — an unfair dismissal or general-protections dismissal claim must be lodged within 21 days. For decisions that matter, contact the Fair Work Commission, the Fair Work Ombudsman, your union, or an employment lawyer.
