What are the visa options and requirements for staying in Thailand for 3 to 4 months as an Australian citizen?

Travelers from Australia can stay in Thailand for 3 to 4 months. Upon arrival, they receive a 60-day visa exemption stamp, which can be extended for an additional 30 days at a local immigration office. To extend their stay to up to 5 months, they can do a border run to a neighboring country and re-enter Thailand for another 60-day exemption. If further extensions are desired, an additional 30-day extension can be obtained, allowing for a total stay of up to 6 months. However, for those looking to open a bank account in Thailand, a long-term visa is required, as short-term visas do not qualify.
