I am pressed for time to apply for a tourist visa, its my second visit to thailand. The first time i had a tourist visa. If i dont get a tourist visa before i go, do i just get 30 days on arrival?

Depends on your nationality. Have you looked at the immigration website to see if you are elgible for a 30 day visa exempt entry?

I think you are Australian, who get 30 days when traveling to Thailand by air.

Make sure you have a ticket out of Thailand within those 30 days, as otherwise the airline might not take you with them.

If you plan to travel around Asia after visiting Thailand you might be better of with a tourist visa, a with a tourist visa you don't need to show a ticket out of Thailand.
