Sri Lanka is fast becoming a place on most people’s must see list (https://www.bloomberg.com/news/features/2017-01-04/where-to-...)
Here is a cheap way to get there with Thai over the travel period February to November 2017 (with blackout periods that do apply).
Sydney to Colombo – $803 (via Bangkok with a 7 hr layover on the outbound leg and a 11 hr layover on the return leg home)
Melbourne to Colombo – $845 (via Bangkok with a 1 hr layover on the outbound leg and a 1 hr layover on the leg home)
For those departing from Sydney with long layovers. Australian passport holders can receive a free visa on arrival and that be used to jump on the airport rail link and head into Siam square in downtown Bangkok for a meal, shopping at MBK, Paragon etc.
