The Competitive Carriers' Coalition has expressed concern that NBN Co is not subject to full ACCC oversight.

NBN Co chief executive Mike Quigley has told a senate committee the national broadband network roll-out would make use of locally-produced product to the "maximum extent," dismissing analysis that Australian firms and Australian staff were being by-passed.

The chairman of the joint parliamentary oversight committee on the NBN Rob Oakeshott says workforce-related issues arising from the $11 billion Telstra-NBN Company deal might add to the cost of the national broadband network roll-out.

The NBN Company expects to make its purchasing decision for two satellites for the national broadband network within the next "couple of months" before turning its attention to finding a supplier for its earth-based satellite services.

The NBN Company is likely to withdraw a request for a "price shock mechanism" - which would allow it to increase prices for its wholesale services by up to five per cent above inflation - as being of little value, NBN Co chief executive Mike Quigley has told a senate committee.

A submission to the ACCC from NBN Co seeks to increase prices for high end broadband services by inflation plus 5% over the next 30 years, which will result in massive charges without a competing service in coming years, according to former Optus senior executive turned Liberal MP Paul Fletcher.

Willunga High School, in the rural town of Willunga, about 47 kilometres south of Adelaide, is set to experience broadband through the National Broadband Network (NBN), as the first fibre-based site in South Australia is launched today.

A bunch of new sites for the national broadband network are due to begin construction in NSW, ACT and QLD between August and the end of the year, with two NSW locations to be first cabs off the rank.

The boss of NBN Co, Mike Quigley, has launched a broadside at news outlets who have published what he calls misleading stories about the recent hacking affair concerning NBN provider Platform Networks. NBN Co is concerned that reports have incorrectly portrayed the security breach as a vulnerability of the NBN itself.
