I'm just double checking that I don't need one if I'm only staying in Thailand for 5 days. From memory, I don't think I need one right?
With an Aussie passport you can enter thailand for 30 days if flying in (internationally) or 15 if crossing the border by land. I've done both myself but the Aus Govt. site confirms as well; https://smartraveller.gov.au/countries/thailand
