i live in AUSTRALIA and have been told that i do not need to apply for a visa for Thailand because i will be there for less then 30 days. Is this true if not where can i get a visa application form

In SE Asia , the only Visa that you need to obtain prior would be a visa for Vietnam and Laos. Thailand,Malaysia, Singapore, Brunei,its all visa upon entry, Cambodia you can buy one upon entry.

thanks for that
