My question is to the Prime Minister. Last night in Senate estimates it was revealed that the government has already ordered 1,800 kilometres worth of copper to make its second-rate nbn work. That is almost enough copper to run between here and Alice Springs! Prime Minister, how much more copper will you need to make your second-rate version of the nbn work? And why is the government investing in 20th century copper when Australia really needs a 21st century national broadband network?
