Australian going to Bangkok.
Should I be applying for a tourist visa, or can I do the 45 day visa on arrival and extend while I'm there?
TLDR : Answer Summary
An Australian traveling to Bangkok can choose between applying for a tourist visa, which allows for a 60-day stay, or utilizing the visa on arrival for 45 days. Both options permit a one-time extension of 30 days at a local immigration office for a fee of 1,900 THB.
