If you have any big trip or holiday coming up, you should always keep an eye out for anything happening in that country which is likely to affect your travel plans. This can be anything from natural disasters such as earthquakes to political unrest.
For example, if you had been planning to go to Australia in the last few months, you would have had to keep an eye on Australia travel information to make sure that your destination was not affected by the fires or floods which badly hit the country.
Too many people do not have a clue what is happening in the country which they are planning to visit, which is shown by the fact that people were still flying into Tunisia and Egypt for their annual holiday even when the unrest had started and it was not safe to be on the streets.
Many people consult the foreign office website which is the best source of information; although they are always on the ultra cautious side and after reading their advice you might decide to never travel again!
It is better to be safe than sorry, though, and you should always take the advice very seriously, otherwise it will not just be the enjoyment of your holiday that is at risk but your actual health and even life.
