What WA Employers Need to Know About Sexual Offence Allegations in the Workplace

When a sexual offence allegation surfaces in a workplace, the consequences reach further than most business owners and managers anticipate. There are immediate HR obligations, potential impacts on the business’s reputation, and — if the person accused is an employee or senior figure — a legal process that can run for months or years and affect their ability to work in the role at all. Understanding how WA law treats sexual offending, what the process looks like, and where to direct people for proper legal help is increasingly relevant knowledge for anyone running a business or managing people in Western Australia.

What Counts as a Sexual Offence Under WA Law

Sexual offences in Western Australia are primarily governed by the Criminal Code Act Compilation Act 1913 (WA). The Code sets out a broad range of offences, and what constitutes a sexual offence depends on the specific conduct alleged.

The main categories include sexual assault (sometimes referred to as rape), indecent assault, acts of indecency, and a range of offences involving children. Offences involving children are treated particularly seriously and include sexual penetration of a child, indecent dealing, and grooming-related conduct — including online grooming and the production or distribution of child exploitation material.

Some offences hinge on the age of the other person. Others turn on the question of consent, the accused’s state of mind, or the relationship between the parties. Because the offences vary so significantly in their elements and their severity, what applies in one case may not apply in another.

How These Cases Are Prosecuted

In most sexual offence cases, prosecution begins after a complaint is made to police. Police investigate, and if they form the view that there is sufficient evidence, the matter is referred to the Director of Public Prosecutions (DPP). The DPP then decides whether to charge and how to proceed.

What the prosecution must prove depends on the specific offence. For sexual assault, the prosecution typically needs to establish that sexual penetration occurred and that it happened without consent, or in circumstances where consent could not legally be given — for example, where the complainant was asleep, intoxicated to a significant degree, or under the age of consent.

The standard of proof is beyond reasonable doubt. That burden sits with the prosecution throughout. The accused is not required to prove innocence.

In cases involving child victims, the law provides additional protections. Complainants may give evidence via closed circuit television, and certain types of cross-examination are restricted. Suppression orders are commonly sought to protect the identity of complainants.

Which Court Handles Sex Offence Cases

The court that deals with a sexual offence depends on the seriousness of the charge.

Less serious matters may be dealt with in the Magistrates Court, though this is relatively uncommon for sexual offences. The majority of sexual assault and serious indecency matters are heard in the District Court. The most serious offences — including aggravated sexual assault and certain child sexual abuse matters — may proceed to the Supreme Court of Western Australia.

Cases at the District and Supreme Court level are typically heard before a judge and jury, though an accused person can elect to be tried by judge alone in some circumstances. The election to go judge-alone is a significant strategic decision and one that requires careful advice from a criminal defence lawyer.

Common Defences in Sexual Offence Cases

The defences available in a sexual offence case depend entirely on the specific charge and the facts alleged. There is no single approach that applies across the board, and defence strategy is almost always shaped by the evidence.

Consent is the most commonly raised issue in adult sexual assault cases. Where the accused genuinely believed on reasonable grounds that the complainant consented, that may be a complete defence. The reasonableness of that belief is assessed objectively, and it is not enough for an accused to claim subjective belief if the circumstances did not support it.

Other defences that may arise include mistaken identity, alibi, and challenges to the sufficiency or reliability of the prosecution’s evidence. In some cases, the question is not whether sexual contact occurred but whether it was criminal in the circumstances alleged. Expert evidence, digital evidence, and the credibility of witnesses can all become central to how a matter is resolved.

It bears noting that a not guilty plea does not amount to an attack on the complainant, and the court process is designed to assess the evidence impartially. A skilled defence lawyer will ensure the accused’s rights are properly protected throughout.

Consequences of a Conviction

A conviction for a sexual offence in WA carries serious consequences, and the impact is felt well beyond the sentencing date.

Imprisonment is the most immediate consequence for serious offences. Sentences for sexual assault can range significantly depending on the circumstances, the offender’s history, and the presence of any aggravating factors. At the upper end of the scale, lengthy terms of imprisonment are not uncommon.

Beyond imprisonment, a conviction triggers registration on the Western Australian Sex Offender Register. Registration requirements vary in duration depending on the offence and the age of the offender at the time, but they can last for many years — in some cases, for life. Registered offenders must report their personal details to police at regular intervals and comply with restrictions on travel and contact with children.

A conviction also affects a person’s ability to work. Many professional licences and occupational registrations are affected by a finding of guilt, and a conviction effectively bars a person from working in child-related employment under the Working with Children (Criminal Record Checking) Act 2004.

Travel is another area of impact. Many countries will deny entry to a person with a sexual offence conviction, and an Australian passport application can be refused or cancelled where a person is subject to a child protection order or is registered as a sex offender.

Family law proceedings may also be affected. Where a parent has a sexual offence conviction, that can bear directly on custody and contact arrangements involving children.

Why Specialist Legal Representation Matters

Sexual offence cases are among the most legally and factually complex matters in the criminal justice system. The law is detailed, the evidence is often sensitive, and the stakes are too high to leave anything to chance.

A specialist criminal defence lawyer brings experience with how these cases are investigated, charged, and prosecuted. They know how to scrutinise the evidence, advise on the available options, and navigate the court process in a way that protects the client’s interests at every stage — from the initial police interview through to verdict and, if necessary, sentencing.

The right legal advice from the outset can shape the entire trajectory of a case. What you say to police, whether you elect jury or judge-alone trial, how evidence is challenged, and whether to contest a charge or negotiate with the DPP are all decisions that require careful, experienced guidance.

Sex Offence Lawyers in Perth

Finding a criminal defence lawyer who specialises in sexual offence matters is an important first step if you or someone you know has been charged. The following firms based in Perth handle these types of cases.

Podmore Legal

Podmore Legal stands out from most Perth criminal defence firms for a reason that matters more than people often realise until it is too late: in-house barristers. The firm acts as both solicitor and barrister, meaning the lawyer who advises you from the first call is the same person representing you in court. You are not paying for two separate legal professionals, and there is no risk of crucial context being lost when your file is handed to an external barrister the night before a hearing.

The firm is led by Justin Podmore, a former Victorian Bar barrister with over two decades of legal and business experience, and Rebekah Sleeth, who brings more than twenty years of criminal law experience including time as a prosecutor at the Department of Public Prosecutions. That prosecutorial background is a genuine strategic asset — understanding how the DPP builds a case from the inside is a different kind of knowledge to what most defence practitioners have. Justin Podmore has been recognised in the Doyle’s Guide Best Barrister Awards consecutively from 2020 through to 2024.

For those facing allegations that are false, exaggerated, or connected to a parallel family law dispute, Podmore Legal has specific experience in those dynamics and can work to protect parenting arrangements where children are involved.
