NBN South Australia and Northern Territory construction contracts sign

14 November 2011

  • Design and preliminary works underway in Darwin and Adelaide suburbs of Modbury & Prospect
  • Design and construction work for 85,000 premises over next 12 months

NBN Co today announced that Syntheo, a joint venture between Lend Lease Group and telecommunications and utilities builder and manager Service Stream, has secured the contract to build the National Broadband Network in South Australia and the Northern Territory.

The agreement means NBN Co has now established a program of construction works to upgrade the telecommunication infrastructure in every state and territory of Australia.

The Syntheo contract covers the design and construction of the fibre optic network in the NT and SA over a period of two years, with an option to extend for a two further years.

The value of the initial agreement with Syntheo is approximately $141 million, with a potential value of up to $341 million if extended for a further two years. The terms of the agreement with Syntheo are consistent with those NBN Co negotiated for construction in other states and with NBN Co's Corporate Plan, ensuring value for money for the Australian taxpayer.

In September the company won a similar contract to construct the NBN in Western Australia.

NBN Co Head of Construction, Dan Flemming said:

“This contract completes the picture for the NBN as we are now in a position to start rolling out the National Broadband Network in every state and territory across Australia.

“In fact, work in South Australia and the NT is already underway. We engaged contractors on a temporary basis for on-site design and other preliminary site works so Syntheo can hit the ground running.”

NBN Co's 12-month national rollout schedule, released last month, includes nine sites in South Australia covering more than 63,000 premises and two sites in the NT covering 22,000 premises. Over the next year NBN Co and its construction partners will be operating in 60 communities across the country, rolling out fibre past half a million homes and businesses, not including greenfield sites.”

It is estimated that the average time from the start of works at a site to the activation of first services is around 12 months.

The National Broadband Network includes the rollout of fibre-based wholesale broadband services capable at launch of offering peak speeds of up to 100Mbps*. It is planned to roll out fibre to 93 per cent of Australian premises, with satellite and fixed wireless to serve the final seven per cent.
