None of the forums seemed to fit, so asking here. 


I'm off to aussie soon, and I am call for work so might need to access the internet. I expect that I might use anywhere up to about 500mb (at the absolute worst case scenario). 


I am a vodafone on-account customer (thus posting here :) ) . 


What is the most cost effective method? Roaming on Vodafone NZ looks like they charge $30/MB. That is just ridiculous . 


I looked at wifi cafe's etc, but they seem inconvenient. 




So, I see the following options:


1. Buy prepaid mobile usb stick for $119 which includes 500mb data.

But, can I use this in NZ ? Not sure if these things have sims or not. 


2. SImilar to (1), but with telstra. 


3. Buy a prepaid sim in aussie. I can put this into my phone, but is it possible to connect the laptop  to the phone as a 'modem' ??  Should any bluetooth phone allow this? 


And, which operator gives the best deal? I find their websites annoyingly confusing.
