How Things Work in Indonesia

Indonesia does not have a strong tipping culture, but gratuities are genuinely welcomed in tourist areas where service workers earn modest wages. Upscale hotels and restaurants frequently add a 10% service charge plus 11% tax to bills — always check before adding more. At warungs (local food stalls) and local businesses, tipping is not expected at all. For private tour guides and drivers who spend a full day with you, 20,000–50,000 IDR per person is a reasonable and appreciated tip.

Indonesia's public transport varies dramatically by island. Java is the best-served: Jakarta has the TransJakarta BRT bus network, MRT, and commuter rail, while intercity trains connect Jakarta to Yogyakarta, Surabaya, and other cities efficiently. Bali has virtually no functional public transport — tourists rely on scooter rental, hired drivers, or ride-hailing apps. Gojek (Indonesian-founded) and Grab both offer motorbike (ojek) and car options and are the fastest way to navigate traffic in any major city. Blue Bird Group taxis are the most trusted metered taxi company nationwide.

Private hospital quality in Indonesia ranges from excellent in Bali and Jakarta to very basic on remote islands. In Bali, BIMC Hospital (Kuta and Nusa Dua) and SOS Medika are the go-to clinics for tourists, experienced with surf injuries, motorbike accidents, and tropical illnesses. The Siloam Hospitals chain provides consistent quality across major Indonesian cities. Pharmacies (apotek) are widespread and pharmacists dispense many medications without a prescription. Malaria is still present in some eastern islands including Papua and parts of Maluku — consult a travel doctor before visiting these areas.

Drug offences in Indonesia are treated with extreme severity — trafficking carries the death penalty and possession leads to lengthy imprisonment. Multiple foreigners are on death row in Indonesia for drug-related offences. Indonesia's 2023 Criminal Code introduced new provisions restricting sex outside marriage and cohabitation, though enforcement against tourists remains unclear. Aceh province in northern Sumatra operates under Sharia law with its own rules on dress, alcohol, and public behaviour that differ significantly from the rest of Indonesia. Disrespecting religion or religious figures is a criminal offence under blasphemy laws.

Indonesia has national emergency numbers, but response times can be slow outside major cities. The police line is 110, and the national ambulance line is 118 or 119. The Kemenparekraf tourist assistance hotline (1500-454) is specifically designed to help foreign visitors and has English-speaking operators. In Bali, BIMC Hospital (+62 361 761263) and SOS Medika (+62 361 720100) are faster and more reliable for medical emergencies than calling the national ambulance line. Always ask your hotel or accommodation for the most reliable local emergency contacts.

Indonesia's dress expectations vary widely by location. In Bali, beach attire is perfectly acceptable at beaches and resort areas, but shoulders and knees must be covered when entering any Hindu temple — sarongs and sashes are typically available to borrow at temple entrances. In Java, Lombok, Sumatra, and other predominantly Muslim islands, modest dress (covering shoulders and knees) is expected in towns and villages even outside religious sites. Aceh province enforces strict modest dress requirements. In major tourist areas of Bali such as Seminyak and Kuta, casual Western dress is the norm everywhere except at temples.

Indonesia's relationship with alcohol is shaped by its Muslim majority. Bali and major tourist hubs have normal alcohol availability at bars, restaurants, and licensed shops. In Java, many convenience stores (Alfamart, Indomaret) do not stock alcohol, and some areas restrict sales. Aceh province is completely alcohol-free by Sharia law. The minimum drinking age is 21 in some regions. Local drinks include brem (Balinese rice wine) and arak (palm spirit), but cheap or unlicensed arak has caused deaths from methanol poisoning — this is a genuine and recurring danger.

Indonesia has a lively bargaining culture at traditional markets (pasar), tourist craft markets, street stalls, and when negotiating with informal transport providers like becak (cycle rickshaw) and non-metered ojek. A useful starting point is offering 30–40% of the initial asking price, then negotiating upward. Fixed prices apply in malls, supermarkets, and chain restaurants. Bargaining should always be friendly and good-humored — walking away slowly after a counter-offer is a classic and often effective move. In Bali's tourist markets, vendors routinely open with prices 5–10 times higher than what they will accept.

Indonesia is generally very welcoming of tourist photography at landscapes, beaches, markets, and public cultural events. However, key restrictions apply: the inner sanctuaries (jeroan) of Balinese temples are usually off-limits to cameras, and photographing religious ceremonies requires asking first and being sensitive about when and how you shoot. Military installations, police stations, and government buildings should not be photographed. Photographing people — especially during Balinese Hindu ceremonies — without asking is considered invasive; a smile and gesture goes a long way toward getting a warm yes.

Indonesia is a multi-religious country and its holiday schedule reflects this — national holidays include Islamic, Christian, Hindu (Nyepi in Bali), and Buddhist observances. Commercial businesses generally operate 7 days a week. Eid al-Fitr (end of Ramadan) is the most disruptive period: transport is overwhelmed by mass domestic travel (mudik), and many businesses close for 3–7 days. Friday is the Muslim day of prayer and some businesses in Muslim-majority areas close briefly around midday prayer. Bali observes Nyepi (Balinese New Year, usually March) as a 24-hour day of complete silence — the airport closes, streets are empty, and tourists must stay in their hotel.

Gojek — founded in Indonesia — and Grab are both essential apps for getting around Indonesian cities. Both offer motorbike (fastest in traffic) and car options with prices shown upfront. Blue Bird Group is the only metered taxi company widely trusted nationwide — their taxis are light blue with a bird logo and use tamper-proof meters. Fake Blue Bird taxis exist, so check the ID card displayed inside and verify the meter clicks over normally. In Bali, local taxi cartels have historically resisted ride-hailing apps — some areas require passengers to walk a short distance from the pickup point and be discreet.

Tap water in Indonesia is not safe to drink anywhere in the country, including Bali, Jakarta, and major cities. Bottled water is inexpensive (2,000–5,000 IDR for 1.5 litres) and available everywhere. Aqua (owned by Danone) is the most trusted and widely counterfeited brand — always check that the seal is fully intact when you buy. Ice at tourist restaurants and hotels is generally produced from treated water and is safe; ice at roadside warungs is more of a risk. Brushing teeth with tap water is not recommended, especially for those with sensitive stomachs.

Cash remains king in Indonesia outside of major malls, chain hotels, and some Bali tourist restaurants. ATMs from BCA, Mandiri, BNI, and BRI work reliably with most international cards, though fees of 25,000–50,000 IDR per withdrawal are common. ATMs in popular tourist areas frequently run out of cash on public holidays — withdraw in advance. Currency exchange is widely available in Bali, but unauthorized money changers use trick counting techniques to shortchange tourists; only use authorized exchange counters at banks, airports, or official money changers with a clearly displayed rate board.

Indonesia's major carriers are Telkomsel (best coverage including remote areas), Indosat Ooredoo (IM3, good value data packages), XL Axiata, and Smartfren. SIM cards are cheap and data packages are very affordable — expect to pay around 50,000–100,000 IDR for a SIM with generous data. All purchases require passport registration, which is done at the point of sale. Buy at airports (more expensive but convenient), official carrier stores in malls, or convenience stores. eSIMs from providers like Airalo work well in Indonesia and avoid the registration process. Coverage can be patchy on outer islands and in highland areas.

Indonesia runs on 220V/50Hz using Type C (two round pins) and Type F (two round pins with grounding clips) sockets — identical to continental Europe. Travellers from the UK will need a Type G to Type C/F adapter. Visitors from the USA, Canada, and Japan need a plug adapter and should check that their devices support 220V (most modern electronics do). Power outages (PLN blackouts) occur in rural areas, on some outer islands, and occasionally in parts of Bali — a power bank is a useful backup. Some budget accommodations have only a few sockets per room.

Indonesia, particularly Bali, is one of Southeast Asia's more scam-prone tourist environments. The most frequent scams target newly arrived tourists at airports (overpriced unlicensed taxis), at money changers (trick counting with sleight-of-hand), and at temples (strangers informing you of a 'special ceremony today' that requires a large donation). Fake Blue Bird taxis — cars painted to resemble the trusted brand — operate in some areas. Tour operators sometimes double-book or fail to deliver services; always use established operators with reviews. Online rental and accommodation fraud is also increasing.

Indonesia is considered relatively safe for tourists by Southeast Asian standards. Violent crime against foreigners is rare. The main risks are opportunistic theft: bag snatching by motorbike riders (especially in Kuta, Denpasar, and Jakarta markets), pickpocketing in crowded markets and on public transport, and beach theft while you swim. Leaving valuables visible in a parked car or unattended on a beach is a common way tourists lose belongings. Bali's nightlife areas (Kuta, Legian) have issues with drink spiking and aggressive touts. Terrorism risk is present — Indonesia has a history of attacks, though large-scale incidents have been rare since the 2000s.

Indonesian culture — across both its Hindu-Balinese and Muslim-majority communities — places significant importance on courtesy and respect. The left hand is considered unclean and should not be used for passing food, money, or gifts. Pointing with the index finger is considered rude; use your thumb or an open hand instead. Touching someone's head — even children's — is deeply disrespectful. Greet elders and people of higher status with a slight bow or nod. Public displays of affection between couples are frowned upon throughout Indonesia, even in Bali. Remove your shoes before entering private homes and places of worship.

Bahasa Indonesia is the official national language, used across all of the country's 17,000 islands despite hundreds of regional languages (Javanese, Balinese, Sundanese and more) being spoken locally. It is phonetically regular with no tones, making basic phrases relatively easy for English speakers to learn. In Bali, Lombok, and tourist zones of Java, English is widely spoken in hotels, restaurants, and tour operations. Outside tourist areas, English knowledge drops significantly and a few phrases of Bahasa Indonesia are warmly appreciated and practically useful. Indonesian people are generally patient and delighted when visitors attempt their language.

Indonesia's 54,000 km of coastline includes some of the world's most spectacular beaches and marine environments. Bali's south coast (Seminyak, Kuta, Uluwatu) has powerful surf that is dangerous for swimmers without experience — respected breaks that claim lives every year. The Bukit peninsula and Nusa Dua have calmer conditions. Lombok, the Gili Islands, Komodo, and Raja Ampat offer extraordinary snorkelling and diving. Stonefish, sea urchins, and sharp coral present injury risks — reef shoes are recommended for non-sandy beaches. Jellyfish are seasonal, particularly around May and November. Strong currents in the straits between islands can be treacherous.

Indonesia drives on the left side of the road, following the British/Australian convention. Scooter rental is extremely popular with tourists in Bali and is often the most practical way to get around, but motorbike accidents are the single leading cause of tourist injuries and deaths in Indonesia. Indonesian traffic is chaotic, roads can be poorly maintained, and driving at night dramatically increases risk due to poor lighting and unmarked hazards. An international driving licence (IDP) is legally required to drive in Indonesia. Police checkpoints target tourists on motorbikes and fines for not having a licence can be issued, though informal payments are common.

Indonesia has one of Southeast Asia's most diverse and celebrated cuisines. Each island and region has its own specialities — Padang food (West Sumatra), Balinese suckling pig (babi guling), Javanese gudeg (jackfruit stew), and Manado's spicy seafood are just a few examples. Warungs are small family-run food stalls that serve fresh, authentic food at very low prices and are generally safe to eat at when busy. Street food at popular stalls is typically fine. Sambal (chili paste) accompanies almost every meal — ask for 'tidak pedas' (not spicy) if needed. Halal food is dominant across most of Indonesia; pork is available in Bali and Chinese restaurants elsewhere.

Indonesia is home to the world's largest Muslim population alongside significant Hindu (Bali), Christian (East Indonesia, Flores, parts of Sulawesi), and Buddhist communities. At mosques, non-Muslims are generally welcome outside prayer times — remove shoes, cover shoulders and legs, and women should cover their hair. At Balinese Hindu temples (there are over 700 in Bali alone), a sarong and sash are mandatory and are usually provided at the entrance for a small fee. The UNESCO sites of Borobudur (Buddhist) and Prambanan (Hindu) near Yogyakarta charge entry fees and require modest dress. Menstruating women are traditionally asked not to enter the inner sanctuaries of some Balinese temples.

Indonesia is tropical with year-round warmth (25–33°C), shaped by a dry season (April–October) and a wet season (November–March). The dry season is generally the best time to visit most destinations. Bali's peak season is July–August (dry, busy, expensive) with May–June offering an excellent balance of good weather and fewer crowds. The wet season brings heavy afternoon downpours but mornings are often clear and prices drop significantly. Different islands have slightly different peak periods: Komodo and Flores are best April–June (calmer seas for diving), while Raja Ampat diving peaks October–April. The highlands of Sumatra and Java are cooler year-round.

Indonesia is one of Southeast Asia's best-value destinations when you travel like a local. Warungs serve generous, delicious meals for 15,000–30,000 IDR (under $2 USD). Gojek food delivery (GoFood) brings restaurant meals to your door at local prices with no tourist markup. Angkot (local minibuses) are extremely cheap for short urban hops if you know the routes. Temple entry fees are usually 30,000–75,000 IDR. Free beaches are abundant — you only pay for sunbeds. Booking accommodation directly with smaller guesthouses, especially outside peak season, often yields significant discounts over booking platforms.
