Methanol poisoning can feel like an ordinary hangover at first, and Smartraveller, the Australian Government’s travel advice service, says symptoms can take 12 to 24 hours to appear. A hangover that is worse than it should be, or gets worse over time, is the warning sign. If that happens after drinking overseas, get medical help straight away and tell the staff methanol is a possibility.
Key facts
- Methanol symptoms can take 12 to 24 hours to show, per Smartraveller

Why methanol is the risk to know about
Methanol is a toxic alcohol that can end up in spirits and cocktails made with counterfeit or badly made drinks. You cannot see, smell or taste it in a mixed drink. The case that changed how Australia talks about this was Vang Vieng in Laos, where six people, most of them young and on a once-in-a-lifetime trip, died in a mass methanol poisoning. Best friends Bianca Jones and Holly Bowles were among them.
After that, Smartraveller began publishing the signs of methanol poisoning, how to guard against drink spiking and broader alcohol safety advice for young travellers.
What to watch for and what to do
Treat a hangover that keeps getting worse as an emergency, not a rough morning. Other travel-health sources add blurred vision, tunnel vision, breathlessness, confusion and severe vomiting to the red flags, and say that several people who shared drinks becoming ill at once should raise concern.
| Sign | What it means | What to do |
|---|---|---|
| Hangover worse than it should be | Smartraveller’s key warning | Do not wait it out. Seek medical help |
| Headache, dizziness, vertigo, fatigue | Early symptoms, usually stronger than a normal hangover | Stop drinking, do not share the drink |
| Vision changes or breathlessness | Serious signs reported by travel-health services | Go to emergency care immediately |
| Friends who drank the same thing are sick | Raises the concern | Get everyone assessed |
Tell medical staff plainly that you suspect methanol, because treatment depends on early diagnosis. Use the local emergency number, or call Smartraveller’s emergency line if you cannot get help easily.
What the Australian Government has put in place
On 18 November 2025 the government launched a campaign with DrinkWise called Drinking? Drink Mindfully, aimed at helping school leavers travel safely and look after their friends. It covers moderating alcohol, the risks of methanol poisoning and what to do when things go wrong. It also added destination cheat sheets for Bali, Fiji, Thailand and Vanuatu on the Smartraveller Partying Safely Hub, plus in-flight videos on Jetstar international flights. Check the hub for the current edition before you fly, because the cheat sheets we found were labelled 2025.
The limit nobody tells school leavers about
Smartraveller is blunt that when you leave Australia you leave behind the emergency and medical services you take for granted at home, and DFAT has repeatedly warned there are limits to the consular help it can give. It cannot pay hospital bills or fly you home. That is why parents should read the policy wording on alcohol-related claims before buying travel insurance, and why leavers should agree a plan with friends: nobody drinks alone, nobody leaves a friend who is unwell, and everyone has the emergency numbers saved offline.
What this means for you
If you are heading to Bali, Fiji, Thailand or Vanuatu, save the Smartraveller number, read the destination cheat sheet, and treat a worsening hangover as a medical problem. Parents: ask your teenager to show you the plan, not just the booking.

Insurance is the other half of the schoolies checklist: what Smartraveller says going uninsured can cost, and what parents should check in a policy.
