Money & costs
The official currency is the Brunei dollar (B$), but Singapore dollars are widely used and have the same value as the Brunei dollar, meaning they are accepted at face value. Don’t worry if you receive Singapore dollars as change from a Brunei dollar bill – you’ll have no trouble using them anywhere in Brunei.
Banks give around 10% less for cash than travellers cheques.
Brunei uses 1c, 5c, 20c and 50c coins, and notes in denominations of B$1, B$5, B$10, B$50, B$100, B$500, B$1000 and B$10, 000.
ATMs are common, and if the banks are closed you can usually find a moneychanger who can also change travellers cheques. Bargaining is reserved for taxis, water taxis and markets (not for food). Credit cards are widely accepted.
