Australia Travel Health Advice
A yellow fever vaccination certificate is required by travellers over one year of age arriving within six days of having stayed overnight or longer in an infected country. No other special immunizations or medications are required for most trips to Australia; however, insect repellents are strongly advised because of the risk of mosquito-borne illnesses. Another health risk is sunburn, and visitors are advised to take precautions. Medical services are excellent, but can be expensive so travellers should ensure that they have adequate insurance. Australia has a reciprocal health agreement with the United Kingdom providing for free hospital emergency medical treatment; proof of UK residence is required.
