I came here mid-April on a 60 day tourist visa and have just gotten a 30 day extension, which will expire mid-July.
My plan is to go to Vietnam for two weeks at that time and then follow the same pattern again, 60 day tourist plus 30 day extension, before returning to Australia mid-October.
My main question was if it was possible to get a 60 day tourist visa before going to Vietnam. Apparently not.
