Quick Answer
To support a sexual harassment claim, you need evidence that the conduct happened and that it was unwelcome and sexual in nature. The most useful evidence is usually notes written at the time, messages, emails and photos, statements from witnesses or people you told, and records of any complaint you made. Claims are decided on the balance of probabilities, not beyond reasonable doubt, but serious allegations need clear evidence. In Australia, complaints to the Australian Human Rights Commission or the Fair Work Commission should generally be made within 24 months.

Sexual harassment is a serious issue that can have a profound impact on the lives of those who experience it. If you have been the victim of sexual harassment, it helps to understand the type of evidence you will need to support your claim. In this blog, we will discuss the different kinds of evidence that may be relevant to a sexual harassment claim and how to gather and preserve this evidence effectively.
Documenting the Incident: Your Most Important Evidence
The first step in gathering evidence for a sexual harassment claim is to document the incident or incidents as they occur. This includes keeping a journal or diary that details each incident’s date, time, and specific details. Be sure to include the names of any witnesses who were present. It’s also a good idea to save any evidence of harassment that you may have received, such as text messages, emails, or voicemails.
Write each entry as soon as you can after the incident, including what was said or done, where it happened, who was there and how you responded. Notes made at the time usually carry more weight than an account written months later. Keep copies somewhere you control, such as a personal email account, in case you lose access to work systems.
If you are thinking about recording a conversation, get advice first. Recording laws differ between states, and secretly recording a private conversation is an offence in several states, including Victoria and Western Australia.
It is important to note that if you believe you are in immediate danger or have recently been physically assaulted, you should contact the police and seek medical attention.
Physical Evidence
Another important type of evidence that may be relevant to a sexual harassment claim is physical evidence. This might include clothing or other items worn or used during an incident of harassment, as well as photographs of any physical injuries sustained as a result of the harassment. Physical evidence can be useful in demonstrating that an incident of harassment took place and can also be used to establish the extent of any bodily harm that may have been suffered.
Statements from Witnesses and People You Told
Seeking support from others is also an important part of gathering evidence for a sexual harassment claim. Talk to friends, family, or a therapist about what you’ve experienced, and ask them to provide written statements about what you’ve told them. Witness statements can be a powerful form of evidence in a sexual harassment case, as they can help to establish the credibility of the victim and provide insight into the impact of the harassment on the victim’s well-being.
Expert Opinion and Professional Advice
Working with an experienced lawyer or a therapist specialising in sexual harassment cases can also be extremely helpful in gathering evidence for a claim. They can guide you through filing a claim and advise you on the type of evidence you will need to support your case. Additionally, they can provide expert opinions that can be useful in proving the harassment claim.
Patterns of Behaviour
Lastly, it’s important to consider the facts of the situation and whether it is an isolated incident or a pattern of behaviour. A pattern of behaviour can be established through various pieces of evidence such as emails, text messages or written testimonials that demonstrate a pattern of behaviour over time.
In any case, it is important to act quickly when gathering evidence. The sooner you start the process, the more likely the evidence will be available and relevant to your claim. Remember that every sexual harassment case is different, and the type of evidence that is necessary to support a claim will depend on the specific circumstances.
It’s important to remember that you are not alone, and there are resources available to help you through the process of reporting and addressing sexual harassment.
It’s always important to seek professional advice and support, understand the legal process, and gather the necessary evidence to make a strong claim.
How Much Evidence Do You Need to Prove Sexual Harassment?
Sexual harassment claims are civil matters, so they are decided on the balance of probabilities: is it more likely than not that the harassment happened? You do not need to prove it beyond reasonable doubt, as in a criminal case. However, because sexual harassment is a serious allegation, decision makers expect clear and convincing evidence. This is often called the Briginshaw principle.
Your own account is evidence. Many cases have no eyewitnesses, so consistent, detailed notes, messages and the people you told at the time can be enough to support your version of events.
Sexual Harassment Evidence Checklist
| Type of evidence | Examples | Tip |
|---|---|---|
| Your own notes | A diary or notes of each incident with date, time, place and what was said or done | Write them as soon as possible and keep them consistent |
| Messages and digital records | Texts, emails, chat messages, social media posts, voicemails, call logs | Screenshot with the date, time and sender visible, and keep the originals |
| Physical evidence | Photos of injuries, clothing or items involved, notes left for you | Store items safely and photograph them |
| Witnesses | Colleagues who saw or heard the conduct | Note their names and what they saw, and ask early while memories are fresh |
| People you told | Friends, family, colleagues, a doctor or counsellor you spoke to at the time | Their accounts can show you raised it when it happened |
| Complaint records | Emails or forms to your manager or HR, and their responses | Keep copies of everything you send and receive |
| Medical and counselling records | GP, psychologist or counsellor notes about the impact on you | These can show the effect of the harassment and support a claim for compensation |
Where Your Evidence Will Be Used
The evidence you gather can support several different paths, and you can get advice on which suits your situation:
- An internal complaint: most employers have a sexual harassment complaint procedure to investigate and resolve complaints.
- The Australian Human Rights Commission: making a complaint is free, you do not need a lawyer, and complaints must be in writing. The Commission may decline complaints made more than 24 months after the conduct.
- The Fair Work Commission: it can deal with sexual harassment disputes and make orders to stop sexual harassment at work. Applications about past harassment should generally be made within 24 months of the last incident.
- State or territory bodies: anti-discrimination bodies in each state and territory can also take complaints.
- The police: if the conduct involved assault, threats, stalking or image-based abuse, it may also be a crime.

Frequently Asked Questions About Sexual Harassment Evidence
1. How much evidence is needed to prove sexual harassment?
Enough to show it is more likely than not that the harassment happened, which is the balance of probabilities. Because the allegation is serious, decision makers look for clear and convincing evidence, such as detailed notes, messages and accounts from people who saw it or were told at the time.
2. Is it hard to prove a sexual harassment case?
It can be, because harassment often happens without witnesses. Cases are much stronger when the person keeps detailed notes, saves messages, tells someone at the time and reports it through a formal process. A consistent account backed by records can be enough.
3. Can I make a sexual harassment claim without witnesses?
Yes. Your own account is evidence, and many claims are made without eyewitnesses. Notes written at the time, messages, and the people you told soon afterwards can all support your version of events.
4. Can I secretly record the person harassing me at work?
It depends on where you live. Recording laws differ between states, and secretly recording a private conversation is an offence in several states, including Victoria and Western Australia. Get legal advice before recording, and focus on written notes and saved messages instead.
5. How long do I have to make a sexual harassment claim?
Complaints to the Australian Human Rights Commission and sexual harassment dispute applications to the Fair Work Commission should generally be made within 24 months of the last incident. State bodies can have different time limits, so get advice early.
