FIBRE optic specialist i3 is to install its first Australian “Fibrecity” network in Brisbane, Queensland.

The Newton-le-Willows company, which uses existing sewerage networks to cut installation costs to provide broadband access to homes and businesses, said the project should take four years.

Elfed Thomas, i3 group chief executive, said: “The key to successful roll-out of fibre to the home is cost. As Fibrecity networks are a commercially funded project, costs are critical.

“Our suite of technologies allows the cost per home to be up to 60% less than traditional build. We have completed a survey of the assets in Brisbane and conclude that these savings are realistic.”

Because the i3 solution is open access, it means any service provider can deliver its product to potential customers.

And Mr Thomas said the group’s Fibrecity networks are complementary to the work of the National Broadband Network (NBN).

“Our work with Brisbane city council complements the NBN’s work by ensuring millions of Australian citizens have access to next generation internet services through a cost effective and commercially viable fibre optic network.”

By the end of 2013, the i3 Group will have connected almost 1m UK homes with broadband capable of supporting speeds of up to 1Gbps on an open access wholesale basis.

Speeds will be faster for business and commercial customers. The company has also completed trials in the USA.
