If you are going on holiday anywhere, be it in the UK or in Australia, you will need to have good travel insurance that is going to cover you in all eventualities. You should look at the different options on a price comparison website, so that you can see how much you should be paying for insurance. You can then choose the option that is right for your particular trip.
Some people prefer to have an annual travel insurance plan. This means that if anything happens at any time, you will be covered. So if you book a holiday and the flight is cancelled, and you weren’t going to get your insurance until a few days before you were due to go, you won’t be covered.
The main thing to do is to read the terms and conditions thoroughly. You must ensure you understand everything and your insurance is everything you think it should be.
