Travel insurance may cover overseas medical expenses, cancellation or amendment costs, lost luggage, travel delays and some personal liability, depending on the policy. Common exclusions can include undeclared pre-existing medical conditions, certain high-risk activities, alcohol-related incidents and destinations subject to government travel warnings. Before buying, check the policy’s limits, excesses, exclusions and medical assistance arrangements in the Product Disclosure Statement. If you have a medical condition or plan adventure activities, ask the insurer how these circumstances may affect cover.
