TecDiveTools lists 24 dive centres teaching technical diving in Indonesia. 9 of them publish course prices, in the currency the shop advertises and with the date each was checked — not converted, and not estimated.
Listings are ordered by how much evidence exists about their technical diving, not by a star rating, with any paid Featured listing shown first and marked as such (how rankings work). 15 of these 24 carry reviews we have read and classified as being about technical or overhead training. The count excludes recreational certifications by name, so a busy resort does not outrank a one-instructor cave operation on the volume of its reef trips. Separately, 11 have at least one instructor whose reviews we have read and summarised — a dive centre carries no synthesis of its own. How we read and count reviews.

TecDiveTools lists 24 dive centres teaching technical diving in Indonesia: Gili Trawangan (6), Jakarta (6), Bali (5), Sulawesi (5), Alor (1) and Lombok (1). The directory is not a census — it lists the centres we have been able to verify, and grows as more are added.
Indonesia sits in the heart of the Coral Triangle, the region with the greatest marine biodiversity on the planet, so the dives you train on are exceptional in their own right — Raja Ampat, Komodo, Bunaken and Lembeh in North Sulawesi, and the walls and currents of Alor. It also has cave diving: the karst of southeast Sulawesi holds hundreds of flooded caves, most still unexplored, with clear water, little flow and warm temperatures all year — conditions closer to Mexico than to most of Asia.
TDI (23), IANTD (5), RAID (4), SSI XR (3), PADI TecRec (3) and UTD (1), counted by how many of the 24 dive centres listed in Indonesia teach each. 9 teach more than one agency. The agency sets the standards and issues the card; the centre sets the price and schedule.
Published whole-course prices at dive centres in Indonesia, by training tier — Extended Range: IDR 10,000,000–20,700,000 (7 centres); Advanced Nitrox: IDR 7,250,000–15,000,000 (6 centres); CCR Air Diluent / MOD 1: roughly US$1,250 to US$1,800 (5 centres, converted from local prices); Intro to Tech / Essentials: IDR 5,050,000–7,500,000 (5 centres); CCR Normoxic / Mixed Gas / MOD 2: roughly US$1,250 to US$1,800 (5 centres, converted from local prices). Each figure is a centre's own published price; they differ mainly in what they include (gas, equipment, dives), so compare inclusions before numbers. Every course page lists the individual prices.
Yes — 9 of the 24 dive centres listed in Indonesia teach cave or cavern courses. Most often: TDI Cavern (8), TDI Intro to Cave (8), TDI Full Cave (6) and IANTD Cavern Diver (3).
Yes — 15 of the 24 dive centres listed in Indonesia teach rebreather courses. Most often: TDI Air Diluent CCR (13), TDI Air Diluent CCR Decompression Procedures (12), TDI Helitrox CCR (7) and TDI Helitrox CCR Decompression Procedures (6). 5 list the rebreather units they support, which matters because CCR training is unit-specific.
Seasons vary by island. Broadly, Bali and the Gili Islands dive best in the dry season (roughly April to November), Raja Ampat's calmer months are roughly October to April, and North Sulawesi dives well most of the year — check the region you are travelling to.
Mostly 27–30°C, but upwellings around Nusa Penida and Alor can drop the temperature into the low 20s °C or below without warning, so carry more insulation than the surface temperature suggests.
