Travel insurance for Heron Island, on the southern Great Barrier Reef, should be built around two things: diving cover and medical evacuation. Heron Island is a small coral cay reached by boat or helicopter from the Queensland coast, prized for its reef diving and snorkelling. That remoteness, and the nature of diving, are exactly what make the right policy matter here.
Diving cover is essential
Heron Island is a diving destination, with reef sites in relatively shallow water, and diving is the main reason to read a policy carefully. Many standard travel policies exclude scuba diving, or cap the depth they cover, and most require you to hold a recognised diving certification to be covered at all. Confirm your policy explicitly includes recreational diving to your planned depth, and crucially, that it covers treatment for decompression illness in a hyperbaric chamber, which can cost tens of thousands of dollars and is not something to leave to chance.
Remote, so evacuation matters
As a small island, Heron has only basic medical facilities, so a serious injury or a diving emergency means evacuation to the mainland by boat, or by air when necessary, to a hospital that can treat it, including one with a decompression chamber. As a guide for this kind of trip, cover with at least US$100,000 for emergency medical treatment and US$250,000 for medical evacuation is a sensible level, given the cost of reaching a suitably equipped hospital. Reciprocal health agreements, where they apply, do not cover ambulance transport or private care, so travel insurance remains important even for eligible visitors.
Choosing a policy
Prioritise diving cover to your planned depth, decompression-chamber treatment, and a strong medical-evacuation limit. Read the exclusions, confirm Australia and remote-island travel are covered, and remember the standard diving rule not to fly too soon after your last dive. Subscription-style cover such as SafetyWing suits long trips, but confirm it covers diving specifically, as many plans do not. Buy the cover before you leave home, because most insurers will not cover a trip once it has already started.
