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

Tasmanian incumbent utility, Aurora Energy, has also remained as primary agent for construction of the site and will conduct "make-ready" procedures at the seven towns.

The utility was initially slated to form a joint venture with NBN Co to form NBN Tasmania. This was scrapped in favour of the Tasmanian wholesaler becoming a wholly-owned subsidiary of NBN Co.

The wholesaler expects to connect services to end-users by the second half of 2012.
