Love this:

3 launched Australia's first 3G mobile network in April 2003. Today, over 2 million customers know first hand just how good it is to be 3.

Our customers enjoy live Mobile TV, full length audio and video music tracks, multiplayer games, Mobile Broadband, face to face Videocalling and much more in 3's Broadband Zones. 

3's Broadband Zones are available in most parts of Sydney, Melbourne, Brisbane, Adelaide, Perth, Canberra and the Gold Coast. Outside of 3’s Broadband Zones we’ve introduced 3G Roaming Zones, so customers with a capable device can now access 3G services in more areas than ever before. And, thanks to our great Caps and plans, they get great value.
