Adelaide International Airport

Official Languages: English

English is the national language and is spoken throughout the country. Visitors may also hear Aboriginal and Torres Strait Islander languages in some communities and regions.

Mobile Network: Mobile coverage is strong in major cities, suburbs, and most large towns. Coverage can become patchy or unavailable in remote inland areas, some national parks, and parts of the outback.

Roaming/SIM/eSIM: Roaming is convenient for short city trips but can be expensive and may have limited data. A local SIM commonly offers better value for longer stays and domestic calling. eSIM is a good option if your phone supports it, with the benefit of activating service quickly without visiting a shop. For remote travel, compare network coverage maps carefully, because provider performance varies significantly outside major population centers.

Card payment is widely accepted in cities, towns, hotels, restaurants, supermarkets, and public transport systems in many areas. Contactless payment is common. Carry some cash for small rural businesses, local markets, and backup in remote regions.

Tipping is not compulsory in Australia, and service staff are generally paid wages rather than relying on tips. In casual cafes, pubs, and everyday services, many people do not tip. In restaurants with table service, rounding up or leaving about 5 to 10 percent may be appreciated for notably good service, but it is not usually expected.

Plug Type: Type I

Voltage: 230V, 50Hz

Adapter: If your devices do not use Type I plugs, you will need an adapter. Check that your chargers support 230V input, although many modern phone and laptop chargers do.
