Yes, travel insurance for Norsup is worth having, and the honesty here starts with recognizing what this place actually is: a small airstrip serving Malekula island in Vanuatu, not a resort hub, reached mainly by travelers heading to remote villages, custom ceremonies, or onward island connections rather than a beach stay. Medical facilities on Malekula are basic, and the practical value of insurance is almost entirely about what happens if something goes wrong far from Vanuatu's main hospital.
Evacuation logistics are the honest core of the risk picture. Anyone with a serious injury or illness on Malekula is typically moved first to Port Vila, Vanuatu's capital on Efate island, where the country's main hospital and better-equipped clinics are located; cases requiring more advanced treatment than Port Vila can provide are often evacuated onward again, commonly toward Australia or New Zealand, given the region's closer air links and larger private hospital networks. That two-step evacuation path is why cover with a real, uncapped medical evacuation benefit matters more in Norsup than in a destination with a well-equipped hospital nearby.
Cyclone season is a genuine and checkable seasonal risk here, running roughly November through April across the South Pacific, and Vanuatu sits directly in that belt; storms during this window can disrupt inter-island flights and strand travelers on Malekula for longer than planned, so trip-delay and cancellation cover matter as much as medical cover if your dates fall inside that season.
There are no named adventure activities to insure against beyond general island travel, village visits, and small-boat transport between islands, so keep cover proportionate to what you are actually doing rather than paying for extras aimed at activities not on your itinerary. Keep any receipts and documentation of evacuation arrangements, and check whether your existing health cover extends abroad and to Vanuatu specifically before assuming it applies.
