Never been asked for flight details in Oz. Melbourne.
In fact they tell you not to book until the visa is issued.
$55 for a TR 60 days single.
Cannot see the value in metv if moving around LOS.
Have been asked by Thai Airways wrt visa at departure.
Never in all my years have i been asked regards funds at arrival, or outgoing flight.
(I always have an exit flight and just revise the date. Alternatively you can book and place on hold with Thai Airways, a flight, and it drops off the system if not paid by a set date).
