How do I go about dealing with inbound flight/accomodation section of the application process (DTV) when you don't currently have my flights or accomodation sorted out?

I'm planning to apply tomorrow, I'm in the Phillipines but my flight booking will not be for two months and I'm not sure if I will be in Australia or America at the time, so figuring out flights now is not an easy situation..

Hello from Switzerland. Thanks for admiting me in the group. For me the best is to ask for an O non immigrant visa for people over 50 years old by internet on the website. It is little bit more expensive than 60 days exemption and 1900 bahts for extension visa 30 days and you win lot's of time not waiting and making queue at the Immigration Office and have to pay for taxi go and back.
