The Federal Government says more than 700 new or improved mobile base stations are now on air and providing what it says is better mobile coverage in regional areas, while boosting Australia’s regional economy with more Australians than ever before accessing mobile networks.

The Coalition Government made the right choice back in 2013 to adopt a multi-technology mix for rolling out the national broadband network, ditching a Labor plan to have fibre to 93% of homes and service the rest through fixed wireless and satellite, Communications Minister Paul Fletcher says.

Doubts have been cast on the NBN Co's financial projections and its ability to repay the $19.5 billion that it has been loaned by the Federal Government, with a report from the Australian National Audit Office putting the chances of its financial statements being incorrect as "high".
