Its important if you are going backpacking to get specific backpacker travel insurance rather than an annual standard insurance so that your policy is tailored around a backpacking holiday. One of the main things to look out for is the duration of the policy, with backpacker insurance you may be given the option to extend your policy if your travelling lasts longer than a year giving you the flexibility to enjoy your experience for as long as you can.
A major factor of backpacker travel insurance is the cover you get for going to multiple countries so you don't have to organise insurance cover for each individual country that you decide to visit. Some policies available may cover you to work whilst you are on your travels so you can earn some extra money whilst you are travelling but be sure to check the policy before you start working just in case. SoSmart Money offer you a wide range of backpacker insurances from some of the top providers many of whom will have 24 hour helplines you can call if you run into any trouble whilst abroad.
