Two thirds of the households that could connect to the national broadband network have not done so, according to new weekly figures released by NBN Co.

Nationally, 380,044 premises have been covered by the government-owned company since the project started in 2009, with about 120,800 households or businesses actively using it. Fibre optic cable accounts for 60 per cent of the active connections, satellite 36 per cent and fixed wireless 4 per cent.

From 255,253 premises passed by fibre in brownfields, 78,028 were unable to get a connection.

The interim satellite broadband service offered by NBN Co since late 2011 has been so popular that it has reached capacity in Victoria and was nearing capacity in other states. Rural households that missed out have to wait until NBN Co launches its satellites in 2015.

The weekly distribution figures have been published only since the new government came to office and go back only to the start of this financial year. Statistics for each state were included for the first time this week.
