Your prep checklist
- Travel clinic 4–6 weeks out — Hep A and typhoid; discuss Japanese encephalitis and rabies.
- Malaria is present on Sumba: antimalarial tablets plus night-time bite protection.
- Pack reef-safe SPF 50, a rash guard, reef protection, and a first-aid kit.
- Get travel insurance with adventure cover and medical evacuation.
- Save emergency 112 and BMKG; plan how you’d reach care from remote spots.
Location
Precautions before you go out
Apply broad-spectrum SPF 30–50 before you head out; reapply every 2 hours and after swimming. Water and sand reflect UV, so you burn faster near the coast.
Big, powerful surf (Tarimbang, Occy’s Left) and strong currents. Never surf alone, know your limit, wear reef protection. Caught in a rip? Swim parallel to shore.
Jellyfish, sea urchins and stonefish can be present. Wear footwear on reef; if stung, don’t rub, rinse with seawater (vinegar for box jellyfish) and seek help.
Fierce sun on open savanna and beaches. SPF 30–50, rash guard and hat; reapply every 2 hours and after every surf.
Malaria mosquitoes bite at night — cover up and use repellent from dusk. Avoid street dogs; any bite needs prompt care.
Care is far away and days are hot. Travel with a buddy, carry water and a first-aid kit, and pace yourself.
This guidance is written for ages 12 and up. Younger children burn and dehydrate faster, react more severely to stings and bites, and need closer, hands-on supervision. General information, not a substitute for local warnings or medical care.
