I come to Thailand each year. Next year I want to spend 3 months there in the Australian winter. This year I investigated extending my stay but changed my mind when the cost of changing the date of my return ticket was $AUD680, much more than half the total cost. Next visit I intend to stay 2 months visa free then extend a month. What are the best options for an outward/return ticket? It's obviously financially punitive to change the date and I assume that if I am asked to show an outward flight, a return ticket dated 3 months from arrival would not be accepted. There is always the option to buy a cheap throwaway ticket (if such now exists) to KL or a refundable one. Any thoughts on the best option?

I like to know from someone who left Australia what you need to leave like reason for our gov
