The Australian Labor Party has labelled valuation claims of the national broadband network made by NBN Co chairman Ziggy Switkowski as bizarre and said no evidence has been produced to back up the price tag he has put on the company.

The Australian Labor Party claims the rollout of the Coalition Government's multi-technology mix national broadband network has reached "new depths of confusion", with NBN Co chief executive Bill Morrow saying he is thinking of building a 5G wireless network to bypass parts of the copper NBN that are unreliable or corroding.

A new ACCC co-funded survey has been cited by the Australian Labor Party as showing that 30% of households could abandon the NBN and switch to wireless broadband. The number stands in in stark contrast to NBN Co projections.
