If re-elected, the Coalition will spend $14 million connecting towns on Tasmania's west coast to the National Broadband Network using fibre to the node, bowing to public backlash against original plans to use satellite.

The Coalition said it would abandon the current satellite roll out to more than 2,700 West Coast premises, and help fund fibre optic cable connections to Queenstown, Rosebery and Zeehan, while Strahan would get fixed wireless connection.

West Coast residents strongly oppose plans to connect the region to the NBN using satellite, claiming the connection would be too slow and devastate the local economy.

"The West Coast region is a strong economic performer," federal Liberal MP for Braddon, Brett Whiteley said.

"This plan will ensure it continues to attract new investment to help create jobs and growth for the region.

"The community spoke, I have listened."

In April, federal Labor promised $29 million to connect the region to the NBN using fibre to the node if it was elected.

The federal Communications Minister claimed that proposal was not costed and would take eight years longer to complete compared with the Coalition's plan.

The Tasmanian Government will contribute $4.5 million of in-kind support, by leasing an unused TasNetworks' fibre optic cable available to the NBN at no cost.

Construction would begin around the middle of 2017 if it goes ahead.
