The Australian Department of Health updated its travel health guidelines on June 3 2026 recommending hepatitis A vaccination for all visitors to Indonesia, Thailand and Vietnam. Recent outbreaks in Bali and Phuket recorded over 1200 cases since March. The vaccine provides lifelong protection after two doses.
Free vaccination is available at travel clinics for Australian residents with proof of upcoming travel. The change aligns with similar advisories from the US CDC and UK Health Security Agency. Routine childhood vaccination does not cover the adult traveller population.
Hepatitis A spreads through contaminated food and water common in street markets and beach areas. Previous guidance only targeted high-risk groups such as backpackers staying in budget accommodation. Hospitalisation rates in the current outbreaks reached 15 percent among unvaccinated adults.
Background shows seasonal spikes during rainy periods when sanitation infrastructure is stressed. Tourism recovery after pandemic restrictions increased exposure risks. Airlines have begun including vaccine reminders in booking confirmations for affected routes.
What this means for you
Schedule the first hepatitis A dose at least two weeks before departure at a travel clinic. Carry your vaccination record when entering countries with active advisories. Avoid raw salads and ice in drinks at non-certified restaurants.
Combine the shot with a typhoid vaccine for broader protection on the same visit. Families with children under 12 should verify prior immunisation status. Rebook any trips if symptoms appear within 28 days of travel.
Vaccination removes most risk and allows focus on enjoying local cuisine safely. Health authorities will reassess the guidance after the current outbreak wave subsides.
