Smartraveller's four advice levels, explained

When international news mentions a change to Australia's travel advice, it is usually referring to Smartraveller, the Australian Government's official travel advice service. Its advice for each destination uses one of four levels.

Level 1: Exercise normal safety precautions (green)

Smartraveller says the security situation at level 1 is like that of a large Australian city. That does not mean the risks are identical. Laws and customs can be very different, and you could still face risks such as crime, civil unrest or unique health risks. Overall, the risks are not higher than in an Australian city.

Level 2: Exercise a high degree of caution (yellow)

At level 2, there are more or higher risks than in a large Australian city. Smartraveller is clear that this is not a warning against going. It is a prompt to research your destination and take extra precautions.

Level 3: Reconsider your need to travel (orange)

Level 3 asks travellers to think carefully about whether the trip is necessary.

Level 4: Do not travel (red)

Level 4 is the highest level of advice.

Using the advice well

• Check the advice for your destination before you book, and again before you leave. Levels can change.

• Read the detail, not just the colour. Advice can differ for regions within one country.

• Check entry rules and make sure you have the right documents.

• Get travel insurance. Smartraveller notes that medical care overseas can be costly even where the risks are similar to Australia.

Being away from your usual support can be challenging, even in a familiar-feeling place. A few minutes with the official advice is time well spent.
