The National Broadband Network (NBN) has been switched on in Townsville, the first location in Queensland to get the service.
"The NBN will significantly support growth and create business opportunities for Townsville with its diverse regional economy and strengths in mining and agriculture," Deputy Prime Minister and Treasurer, Wayne Swan, said.
Townsville is one of five mainland NBN first release sites where NBN Co is testing network design and construction techniques ahead of the national rollout.
The trial phase will run until October. Afterwards, users can sign up with their preferred retail service provider.
To date, Armidale, Kiama Downs/Minnamurra and Brunswick have been switched on. Willunga in South Australia is next on the agenda.
"These sites are showcasing the diversity of conditions NBN Co will encounter across Australia in the network rollout," Minister for Broadband, Communications and the Digital Economy, Senator Stephen Conroy, said.
In August, NBN Co announced that progressive construction would start on the rollout of the NBN in second release sites in NSW, Queensland and ACT.
The construction includes new sites in Queensland at Springfield Lakes, Toowoomba and Aspley in the metropolitan area of Brisbane, in NSW at Riverstone in western Sydney and Coffs Harbour, as well as Gungahlin in ACT.
It also includes extensions to existing works in Armidale and Kiama (NSW) and Townsville (QLD).
NBN Co is negotiating construction contracts for the second release sites in other states and the Northern Territory, and expects to finalise arrangements soon.
