that's only 2 months max. When are you going to be here again?
1. I am planning to use my iphone.. from my knowledge I can only get data or voice plan for prepaid.. is that true? and which one would you recommend the best?
I don't know. Perhaps others can help you. You may have to buy a short-term phone here.
2. Should I bring cash to stay there for 3 months? or is there a way where I can withdraw money from my Australian Bank? Sorry for the novice question.
We can't answer that without knowing your bank. Ask them! I'd want to be safe with enough cash for a fast exit, so yes, bring
some.
3. How cold is the weather in February?
Have you checked Google?
Let me google that for you
