4G In Australia Right Now

There are only two networks offering 4G products in Australia at the moment (March 12) Telstra and Vividwireless.

Optus will be rolling out 4G services in the 1800MHz band from April 2012 to Newcastle, Port Stephens, the Hunter Valley and Lake Macquarie areas. Optus 4G services will also be delivered to Sydney, Melbourne and Perth from mid-2012 with further expansion expected shortly after.

Despite spending billions, Vodafone appears to have little interest in LTE, with CEO Nigel Dews stating that “We’re less inclined to do the aggressive talking about LTE”.

Optus announced in February that it had entered a conditional agreement to buy Vividwireless's customers and network assets in a deal involving a cash consideration of $230 million. (But it won't be the customer base they're after - Ed.)
