Money and Payment Tips for Southeast Asia
- ATMs vs currency exchange: ATMs in Thailand (Bangkok Bank, SCB) give good rates; avoid Superrich-style exchange at airports. In Bali, withdraw at major bank ATMs in the first few towns — don't exchange at the airport. In Vietnam, ATMs are the easiest option; cash is more commonly required than in Thailand.
- Card fees: Use a no-foreign-transaction-fee card (Wise, ING Orange Everyday, Bankwest Zero) to avoid 2–3% fees on every purchase. This saves AUD $60–150 on a 3-week trip.
- eSIM vs local SIM: An Airalo multi-country eSIM covering Thailand, Vietnam and Indonesia costs approximately AUD $25–35 for 30 days and is simpler than buying local SIMs in each country.
Travel Insurance for Southeast Asia
Medical costs in tourist areas of Southeast Asia are manageable for minor illness, but serious accidents or required evacuation to Australia can cost AUD $30,000–100,000+. Compare travel insurance options before you go. For Southeast Asia specifically, ensure your policy covers motorbike accidents (a common exclusion — and the most common cause of serious injury for Australian tourists in Thailand and Bali).
