Take out comprehensive travel insurance before you depart to cover overseas medical costs, including medical evacuation.
Remember, regardless of how healthy and fit you are, if you can't afford travel insurance, you can't afford to travel. The Australian Government will not pay for your medical expenses overseas or medical evacuation costs. This can be very expensive and cost you many thousands of dollars upfront.

Physical and mental health

Keep your medicines in their original packaging. Always carry a copy of your prescription and a letter from your doctor stating what the medicine is, how much you'll take and that it's for personal use only.

Tropical storms and typhoons

Access to sea ports could also be affected. In some areas, adequate shelter from a severe cyclone may not be available for all those who stay.
Stay up-to-date on weather conditions and forecasts, typhoon watches and warnings throughout your stay. Monitor the
World Meteorological Organisation Severe Weather Information Centre, the
Joint Typhoon Warning Centre and the
Global Disaster Alert and Coordination System.
If a typhoon or severe storm is approaching, follow the advice for natural disasters above and:
