Despite only 50 per cent of residents in the first three Tasmanian release sites taking up the NBN since its installation late last year, business and residential communities have continued to raise concerns that their areas may not receive fibre.

Those areas where fibre installation is not cost effective under current NBN Co plans will receive either fixed wireless or satellite connections with guaranteed speeds of 12 megabits per second (Mbps).

NBN Co is allowing those customers who do not receive fibre to upgrade to a fixed line connection at an extra cost.

Andrew Connor, a spokesperson for consumer lobby group Digital Tasmania, argued that not all of the communities raising issues had the right to do so.

"The issue of the Bell Bay business park is a little odd... those businesses already have access to fibre services if they're prepared to pay for it and the very large corporations there do," he said. "They also have ADSL available in that area already so it's a relatively level playing field there already.
