There are various "wireless" technologies available in Australia today.
1. WiFi which most laptops have these days. This works over a short distance in suitably equipped homes, business and hot-spots. The range is generally under 100m.
2. 3G is what is sold by Telstra, Vodafone, Optus, 3, etc and is generally only available in or near major cities. You can access the 3G network from a cellphone/cable to laptop or USB modem. Outside the 3G coverage area, you can get GPRS everywhere else that you can get mobile coverage from that network. This is slow - like just a tad faster than dialup.
3. NextG is a nationwide network from Telstra which gives nationwide broadband over your cellphone/cable to laptop or USB modem. By nationwide, you get coverage which is similar to the CDMA network and broadband works everywhere your NextG cellphone works.
Does VOIP work over any of these. Yes, VOIP works on WiFi but 3G and NextG, I have not tried so don't know but should work. VOIP did not work too
well on the old GPRS network which is option2 above when you are away from 3G coverage
Hope that this helps
