Optus announced plans to launch commercial LTE service in April 2012. 
The rollout will begin with Newcastle, Port Stephens, the Hunter Valley and Lake Macquarie areas. A 4G capital city rollout will begin next month with Phase One to deliver LTE services in Sydney, Melbourne and Perth from mid-2012. Phase Two of the rollout will see an expansion of 4G LTE services to other capital cities and selected regional centres.
Optus also announced that it just became the first Australian carrier to be awarded a licence to trial LTE services in the 700 MHz spectrum band. A trial will take place in Bendigo, Victoria and will be the first time in Australia that the former analogue TV frequency will be used for 4G services and applications. Huawei has been selected for this trial.
