Responding to a workplace discrimination complaint

Discrimination complaints may be brought under multiple regimes. Employers must investigate promptly, preserve evidence, and respond substantively to any external complaint while managing the internal relationship and psychological risk.

In short

This is an 8-step workflow for advising an Australian employer on responding to a workplace discrimination complaint under the Fair Work Act 2009 (Cth), Australian Human Rights Commission Act 1986 (Cth), and state anti-discrimination legislation.

Time: 15-30 hours depending on the forum and complexity of the allegations.
Audience: AU employment lawyers advising an employer on an internal discrimination complaint or an external complaint filed with the AHRC, a state tribunal, or the FWC.

Prerequisites

  • Insurer notified where required
8 steps

The workflow

1

Identify the legal pathways

Identify which regimes may be engaged — Fair Work Act s 351 general protections, AHRC Act, state anti-discrimination acts — and any applicable time limits.

Tools: Quillio
Fair Work Act 2009 (Cth) s 351
2

Preserve evidence

Issue a litigation hold over relevant documents, emails, and chat messages. Capture manager notes and any HR system records.

3

Conduct a confidential investigation

Engage an internal or external investigator to interview witnesses, gather evidence, and apply the Briginshaw standard. Maintain legal privilege where possible.

Tools: Quillio
Briginshaw v Briginshaw (1938) 60 CLR 336
4

Manage parallel proceedings

Manage any parallel proceedings — AHRC conciliation, state tribunal, FWC, or workers compensation — and coordinate responses to avoid inconsistency.

Tools: Quillio
5

Assess liability and defences

Assess the employer's direct and vicarious liability and whether any statutory defence (e.g. reasonable management action, all reasonable steps) is available.

Tools: Quillio
Sex Discrimination Act 1984 (Cth) s 106
6

Consider conciliation and settlement

Consider early conciliation under the AHRC Act or at the FWC. Prepare a settlement framework including deed terms and confidentiality.

Tools: Quillio
Australian Human Rights Commission Act 1986 (Cth) Part IIB
7

Respond formally to the complaint

Draft a formal response to the complaint addressing each allegation, tendering supporting material, and advancing any positive defence.

Tools: Quillio
8

Remediate and prevent recurrence

Implement remediation steps — updated training, policy changes, and targeted action — to address any systemic issues identified during the investigation.

Outcome

What you will have at the end

A documented investigation and response that protects legal privilege where possible, satisfies WHS and anti-discrimination obligations, and positions the employer for conciliation or hearing.

Common issues

  • Not preserving chat and email evidence early enough
  • Privilege breaks because HR rather than legal led the investigation
  • Failing to address vicarious liability and all-reasonable-steps defence
  • Inconsistent responses across parallel forums
  • Missing AHRC or state tribunal response deadlines
