The latest three-year rollout plan from government-owned NBN Co. Ltd to deliver on its mandate of building the country’s national broadband network has been assailed by the opposition as a “ramp Evel Knievel couldn't jump”.

The new NBN plan will deploy Hybrid Fibre Coaxial (HFC) cable technology to areas that will receive ultra-fast broadband service through existing cable TV networks. NBN currently focuses on deploying multiple access technologies and HFC is an important part of this mix.

The construction plan reveals areas where NBN will deploy HFC cable technology. This project is expected to complete in September 2018.

Most of these areas are in NSW and Victoria. NBN said the project will cover over two million homes in each state. Some 1.5 million homes in Queensland will benefit from the project.

NBN also reported construction will start on 802,540 homes in Western Australia; 617,300 in South Australia and 104,500 in Tasmania, said The Australian. About 81,200 homes in ACT and 11,300 in the Northern Territory will be made ready to receive the new service.

In total, some 7.5 million homes will be prepped to receive the ultra-fast broadband service within the next three years. NBN ultimately intends to reach about 9.5 million homes by September 2018. The timetable can be found here on the NBN website.

Critics, however, contend HFC networks aren’t robust enough to provide adequate services to households. NBN has denied this, saying the infrastructure will be improved to cope with demand.

Communications Minister Mitch Fifield has sided with NBN, saying NBN’s plan to attain full rollout by the 2020 deadline is "concrete, realistic, achievable". Shadow Communications Minister Jason Clare, however, belied Fifield’s claims.

"The NBN rollout plan (is) a ramp Evel Knievel couldn't jump," said Clare.

He earlier said Labor will speed-up the number of homes connected via fibre-optic cables should Labor win the next federal election. Labor has always insisted that Prime Minister Malcolm Turnbull’s Coalition erred when it chose to use a mix of cheaper but slower technologies that rely on copper phone lines to deliver broadband to Australian homes.
