Hey guys

I've been thinking about backpacking through asia and australia, so to have a chance to complete this, i need someone with experience in backpacking.
I got tons of questions, and i hope most of em' can be answered by you
I dont want to live luxurious or anything, and just live by the day.

1. Does someone got a route, or some ''must-see'' places in asia?

2. Where would you start your destination?

3. What is and realistic budget pr. day ?

4. What have you experienced was the must have items on your tours ?

5. Wich countries and / or should i avoid?

I'm looking forward to your answers !
