The end-of-year celebration is a great way to thank your team for their hard work. But from a legal perspective, a work Christmas party is an extension of the workplace. The same obligations that apply in the office, on the shop floor or on site on a Tuesday morning still apply when the music is playing and the drinks are flowing. Here is what the law expects, a cautionary tale from the Fair Work Commission, and a practical checklist to keep this year’s celebration safe, respectful and compliant.
In short
- Your work Christmas party is legally an extension of the workplace — WHS, anti-discrimination and Fair Work obligations all still apply.
- Under the positive duty, employers must show what they did beforehand to prevent sexual harassment, not just how they responded afterwards.
- Unlimited, unsupervised alcohol is the single biggest risk factor — and it can make misconduct harder to act on.
- Use the before, on the night and after checklist below, and get advice early if something goes wrong.
The work Christmas party is still work
Every year, HR advisers and employment lawyers across Australia see the same fallout in January: complaints of sexual harassment, injuries, fights, inappropriate social media posts and unfair dismissal claims, all traced back to a single evening. Most of it is preventable with some planning.
What does the law expect of employers?
Several overlapping legal frameworks apply to work functions. Together, they mean employers must be proactive, not just reactive.
Work health and safety (WHS)
Under WHS laws, a person conducting a business or undertaking (PCBU) must ensure, so far as is reasonably practicable, the health and safety of workers. This covers physical risks such as intoxication, slips and falls, venue hazards and travel home. It also covers psychosocial hazards, which now expressly include sexual harassment, bullying, aggression and violence. A work party with free-flowing alcohol, blurred boundaries and reduced supervision is a known high-risk environment, so it needs to be assessed and controlled like any other hazard.
The positive duty under the Sex Discrimination Act
Since December 2022, employers have had a positive duty under the Sex Discrimination Act 1984 (Cth) to take reasonable and proportionate measures to eliminate sexual harassment, sex-based harassment, hostile work environments and victimisation, as far as possible. The Australian Human Rights Commission has had powers to enforce this duty since December 2023. This is a fundamental shift: it is no longer enough to respond well to a complaint after the event. Employers must be able to show what they did beforehand to prevent harm — and the Christmas party is one of the most obvious places to start.
The Fair Work Act
Since March 2023, the Fair Work Act 2009 (Cth) has expressly prohibited sexual harassment in connection with work (section 527D). Workers can bring claims through the Fair Work Commission, and both the harasser and the employer can be liable. The first concluded decision under this provision, Mejia v Capital City Café-Bar [2026] FedCFamC2G 468, resulted in around $90,000 being ordered against a business owner, including compensation and penalties — and because the company had been wound up, he was personally liable for the full amount.
Vicarious liability
Employers can be held liable for the unlawful conduct of their employees at work-related events, including discrimination, harassment and bullying. The main defence is showing that all reasonable steps were taken to prevent it. Without clear policies, training and active management on the night, that defence is very hard to make out.
Your own policies and codes of conduct
Your code of conduct, harassment and bullying policies, and alcohol and drug policies all apply at a work function. Make sure they clearly say so. If you ever need to take disciplinary action for party misconduct, your ability to do it fairly depends on staff having known the standards in advance.
A cautionary tale: when the employer contributes to the problem
The best-known Australian Christmas party case is Keenan v Leighton Boral Amey NSW Pty Ltd [2015] FWC 3156. The company held a party with unlimited alcohol and no manager supervising its service. An employee became heavily intoxicated, swore at a director and senior staff, and made offensive comments to female colleagues. He later went to an unofficial after-party at a public bar, where he kissed one colleague without consent and abused another.
He was dismissed, and the Fair Work Commission found the dismissal unfair. The Commission held that the after-party conduct happened outside the official function, so it fell outside his employment. It was also critical of the employer for allowing unlimited, unsupervised alcohol, and the employee’s level of intoxication was a factor in finding the dismissal harsh.
The lessons for employers are clear:
- If you supply unlimited alcohol, it is harder to hold employees fully accountable for intoxicated behaviour.
- A clear start and finish time matters, and so does making it plain that after-parties are not work-endorsed.
- Under today’s positive duty and the Fair Work Act’s broader “in connection with work” test, employers should not assume an after-party will always sit outside their responsibility. Courts look at all the circumstances, including who organised it and who paid.
Your Christmas party compliance checklist
Before the event
- Complete a simple risk assessment covering the venue, alcohol, activities, transport and any known workplace tensions.
- Review your code of conduct, harassment, bullying, and alcohol and drug policies, and confirm they apply to work functions.
- Send a friendly reminder to all staff a week or two before the event outlining expected behaviour, consequences of misconduct and how to raise concerns.
- Brief managers and supervisors on their role on the night, including watching for warning signs and stepping in early.
- Set a clear start and finish time in the invitation, and state that any after-parties are not organised or endorsed by the business.
- Choose a venue with responsible service of alcohol (RSA) trained staff, and check accessibility, lighting and safe exits.
- Plan inclusive timing, food and activities, considering dietary, cultural, religious and family needs. Make attendance and drinking optional.
- Arrange safe transport options, such as taxi vouchers, rideshare credits or a shuttle bus.
On the night
- Limit alcohol through a set bar tab, drink cards or a time limit rather than an open, unlimited bar.
- Provide plenty of substantial food and non-alcoholic drinks.
- Nominate one or two senior people to stay sober, supervise, and act as contact points for any issues.
- Step in early if behaviour becomes inappropriate and remove anyone who is unsafe or breaching policy.
- Avoid games, themes, costumes or Secret Santa gifts that could be sexualised, demeaning or exclusionary.
- Close the function at the advertised time and help people get home safely.
After the event
- Remind staff about social media expectations, particularly around posting photos of colleagues without consent.
- Follow up promptly on any incidents, injuries or concerns raised.
- Note what worked and what didn’t, so next year’s risk assessment is better.
If something goes wrong
Even with good planning, incidents can still happen. How you respond is just as important as what you did to prevent them.
- Take every complaint seriously, even if it comes weeks later, involves a senior person or seems minor.
- Act promptly and confidentially. Ensure the person raising the concern is supported and protected from victimisation.
- Manage immediate risks, such as changing rosters or reporting lines while the matter is looked into.
- Follow a fair process. Put allegations to the respondent, give them a genuine opportunity to respond, and make findings based on the evidence.
- Be consistent. Outcomes should be proportionate and in line with how similar conduct has been treated in the past.
- Report notifiable incidents to your WHS regulator where required, and notify your workers’ compensation insurer of any injuries.
- Get advice early if the matter is serious or complex. An independent workplace investigation can protect both the people involved and the business.
Celebrate well, and celebrate safely
A Christmas party should be a highlight of the year, not the start of a complaint, claim or investigation. With the positive duty now firmly in place, employers need to show they have thought ahead and taken reasonable steps to keep everyone safe and respected.

Frequently asked questions
Is a work Christmas party covered by workplace laws?
Yes. A work Christmas party is treated as an extension of the workplace, so your work health and safety, anti-discrimination and Fair Work obligations all still apply, including the duty to manage psychosocial hazards.
Can an employer be held liable for an employee’s behaviour at a Christmas party?
Yes. Through vicarious liability, an employer can be responsible for unlawful conduct such as harassment or bullying at a work event. The key defence is showing you took all reasonable steps — clear policies, staff reminders, manager briefings and active supervision — to prevent it.
Is an after-party the employer’s responsibility?
Not automatically, but don’t assume it sits outside your responsibility. Courts look at all the circumstances, including who organised and paid for it. Set a clear finish time and make it plain that any after-party is not organised or endorsed by the business.
Can an employee be dismissed for their behaviour at a work Christmas party?
Yes, but the dismissal must be fair. As the Keenan case showed, supplying unlimited, unsupervised alcohol can make it harder to hold an employee fully accountable and can make a dismissal harsh. Fair process and consistency are essential.
What is the positive duty?
Since December 2022, the Sex Discrimination Act has required employers to take reasonable and proportionate steps to eliminate sexual harassment and related conduct before it happens. The Australian Human Rights Commission can enforce this duty.
How much alcohol should we provide at a work function?
Avoid an open, unlimited bar. Manage alcohol with a set bar tab, drink cards or a time limit, always serve substantial food and non-alcoholic options, and use a venue with RSA-trained staff.
