Australian International School Bangkok’s Soi 31 campus is nestled at 319 Sukhumvit Soi 31 in Bangkok’s Watthana district. It resides in a quiet, leafy residential area of central Sukhumvit, offering a calm environment while remaining well connected—taxis, BTS/MRT stations, and main road access are convenient. The campus shares proximity with the AISB Sports Centre and Innovation Centre and is just minutes away from the Soi 20 campus, connected by a supervised shuttle service, making transitions and shared activities easy.
AISB operates a two-campus model: Soi 20 serves the Early Years (Nursery and Year 1), while the Soi 31 campus accommodates the full range from Foundation (Year 1) through to Year 12. This structure clearly distinguishes the youngest learners’ setting from older primary and secondary students, with most of the Foundation–Year 12 progression housed on Soi 31.
AISB operates as a day school.
Support services include a structured EAL program with small-group and intensive options, along with a Learning Support department that provides personalized plans, assessments, and teacher collaboration. The Access and Inclusion teacher coordinates extra help with internal staff and external specialists as needed.
While not formally affiliated with the Australian government, the school’s curriculum and identity are strongly influenced by Australian education.
The school has no religious affiliations.
At the Soi 31 campus, the school day begins at 07:30 for both Primary and Secondary students. Primary classes (Foundation to Year 6) finish at 14:00, while Secondary (Years 7–12) end at 14:50. Breaks and lunchtime are built into the timetable, with meals provided daily on campus. Early Years (Nursery to Pre-Kindergarten) are housed at the Soi 20 campus and follow shorter hours, but Foundation (from Year 1 onwards) transitions fully to Soi 31.
AISB provides optional transportation in partnership with Montri Transport, a well-established Bangkok school transport provider. The service is door-to-door and includes both a driver and an adult supervisor on every route. Terms and conditions for the service are available directly from Montri upon request. This option gives families flexibility and additional safety for young children.
