It is essential that you take out travel insurance if you are planning a visit to one of the countries in Australasia or Oceania. The level of risk varies depending on where you go and a comprehensive policy will protect you against any mishaps. Australia and New Zealand are relatively safe countries; however, there are always additional dangers for first-time visitors. Over-exposure to the sun can lead to heat exhaustion and sunburn, while the waters around Australia are known for their deadly jellyfish. Many of the smaller countries and islands in the Oceania region present additional health risks and there are often limited medical facilities. Papua New Guinea is plagued by inter-tribal violence and crime is common in most urban areas.
