Poor communications reception should no longer cause headaches for towns and villages along the East and West Tamar as fixed wireless accessibility is extended.

Communications connections for the town were previously unreliable and could impact business, according to Greens Beach Store owner Neville Stewart.

Since its NBN launch, the store has  used its connection to secure a reliable EFTPOS connection, browse larger websites and process ordering information with more efficiency.

``Previously we were on a satellite, it was average, we'd drop out,'' Mr Stewart said.

``We had an issue with our landline dropping out _ it was down for about four or five days at one point.

``Now with our NBN we're connected continuously, it's much more professional with our accounts.''

NBNCo spokeswoman Lalla MacKenzie said about 2900 premises, from Greens Beach to White Hills, would fall within the new availability region.

Ms MacKenzie said reliable access to distance education, e-health services and more were significant benefits of fast regional broadband connections.

Telstra Country Wide Northern Tasmania manager Michael Patterson said people, such as Mr Stewart, were promoting NBN in towns across Australia with first-hand experience.

He said the connection speed and reliability would allow video calls to be made between NBN households.
