[quote=brit;259518]4k AUS budget all in is going to be damned tight unless you can get a dirt cheap airfare. It's a lot harder to live cheap on your first time, a lot of people make the mistake of budgeting accomodation then only at looking how cheap the street vendor food is and multiplying up. I assume you want to do stuff while there like go on the daytrips and you're already paying a lot for all this travelling around. QUOTE]
Eljay,
Hope you don't think we're raining on your parade but it's time to do the reality check on your budget, probably based (just to be safe) on assuming that you're travelling alone.
As Brit says, airfare is key. Starting with the $880AUD for the Sydney/BKK flight you will be up to about $1500AUD in airfare costs if you include the side trips to Singapore, KL & Chiang Mai. That leaves an average of 2000 Baht/day
($72AUD/day) and that just won't cut it. For example, a Phi Phi jetboat daytrip is about 3000 Baht per person.
Anyway I'll leave my math lesson right now and I'm sure you'll figure the rest out. If you keep your itinerary to Thailand, it should work for you because then the airfare is manageable. Phuket to Bangkok is only 1700 baht on Fly123 airlines & their other Thai routes are cheap too.
You can still have a fantastic trip but you don't want to get back to Oz and be paying off your credit card bills for years to come!
