The Federal Government is standing by its election promise for a fibre-to-the-node rollout on Tasmania's west coast, the National Broadband Network (NBN) says.

The Government promised to spend $18.5 million connecting premises in Queenstown, Rosebery, Zeehan and Strahan to the NBN with fibre-to-the-node, instead of satellite.

The region is in the electorate of Braddon whose incumbent, Brett Whiteley, was one of three Lower House Liberals who lost their seats in this month's election.

Last year, the NBN said the west coast would be connected to the network using its Sky Muster satellite, not fibre-to-the-node as had been previously planned.

The rollout was halted until it had clarity on exactly what service it was being asked to roll out.

Local authorities and businesses had been concerned the service via the Sky Muster satellite would not provide adequate speeds.

NBN Tasmania corporate affairs manager Russell Kelly said the rollout would continue as planned under the Turnbull Government.

"They certainly will be getting fibre-to-the-node because the NBN rollout is done at the behest of the current Federal Government and the current Federal Government's policy is to move to fibre-to-the-node," he told 936 ABC Hobart.

West Coast Mayor Phil Vickers said he would hold the Government to account.

"Whilst fibre-to-the-premises would be a better fix for all those people that got to have fibre-to-the-node, it's still better technology than the satellite so even if we have to wait until 2018 to have that connected it's worth the while," he said.

There is no timeframe on when the funding would flow to enable work on connecting the towns to begin.

Councillor Vickers said he would be writing to federal Communications Minister Mitch Fifield for details about the timeline.

The Labor Party had promised to spend $30 million to deliver NBN to the region.
