Don't know how good access you have to WiFi hotspots in Melbourne, but here in Sweden they are fairly prevalent. I have access to WiFi when riding the bus or train. Walking in any reasonably populated area you will at any time have access to between 3 and 10 APs. The problem is that you are moving so you go in and out all the time. Now, if you have a smartphone with tethering you can use WiFi on your reader and connect it to the phone and that way access the internet from your reader.
Does the name Pavlov ring a bell?
