Sumba is the Lesser Sunda island east of Bali that feels two centuries removed, savanna, megalithic tombs, world-class surf, and almost no tourism infrastructure outside two luxury resorts.
editorial
The case & the friction.
ExpatWhy editorial
Mid-range bungalows near Waingapu, Waikabubak, or in the Nihiwatu coast region run IDR 5–12 million/mo ($320–760); the luxury enclaves price themselves out of any nomad bracket. A pork-and-cassava plate at a roadside warung is IDR 35,000 ($2.20). Wifi is genuinely poor, 5–25 Mbps in the few connected guesthouses, frequent outages. Telkomsel 4G is the only reliable plan B and only along main roads. This is not a place to work; it is a place to surf and decompress.
At sea level with a dry savanna interior the climate splits hard. The dry season (May–October) is hot (30–34°C) with reliable trade winds and the surf swell at Nihiwatu and Tarimbang. The wet season (November–April) brings daily storms and makes the inland clay roads impassable.
Walakiri Beach is the postcard, mangrove silhouettes at low tide against a wide sky, 20km east of Waingapu. Praijing and Ratenggaro are traditional Marapu-religion villages with thatched peaked-roof houses (the Sumbanese ata) and megalithic stone tombs in the central square, these are living villages, not open-air museums, and a small donation to the kepala desa is expected. The Pasola spear-fighting festival in February–March (lunar dates) is the major ritual event. Nihiwatu (now branded otherwise) put Sumba on the global luxury map but the local economy beyond it remains agricultural. Flights connect Waingapu and Tambolaka to Bali (Denpasar) in 70 minutes. Indonesia's E33G remote-worker visa handles long stays; the B211A is fine for visits under 6 months. English is minimal outside resort staff.

Country baseline, not anchored to schools in this specific city; the real figure for a given school varies with tier, location and grade. Preschool = full-day international preschool, annual. Secondary is an estimate, modelled as a published uplift over primary (low +20%, typical +30%, high +40%), since secondary tuition rises with grade; it is not a separately sourced figure.
Tuition only. Excludes one-off enrolment/capital levies, school bus, lunch, uniforms and exam fees, which add materially at most schools.
