The Member for Ballina, Don Page, today said he was concerned to hear the Federal Labor Government has indicated it wants to reduce the Federal Government's funding contribution for the Pacific Highway upgrade from 80 percent to 50 percent.

"In real dollar terms this means cutting the Federal Government contribution by approximately $2.3 billion," Mr Page said.

"The NSW Government has written an urgent letter to the Federal Minister for Infrastructure and Transport, Anthony Albanese, asking him to continue the funding arrangement that was agreed upon by the former State Government," he said.

Mr Page said the full duplication of the Pacific Highway had long been a priority for the NSW Liberals and Nationals and the State Government supported the Federal Government's objective of getting the project completed by the end of 2016.

"In last year's budget the NSW Government committed an additional $468million to accelerate the upgrade," Mr Page said.

"If we are to complete the Pacific Highway upgrades by the end of 2016 it will cost an extra $7.4 billion," he said.

"The current funding split for the Pacific Highway is 80:20 between the Federal and NSW Governments and it is unreasonable for Mr Albanese to try to reduce the Commonwealth's funding share to 50 percent," he said.

"The Pacific Highway is part of the national highway network and a road of national significance, and it should be given funding priority by the Federal Government so we can get on with the job of getting it duplicated.

"Upgrades of other roads in NSW identified as part of the National Land Transport Network have been at least 80 percent funded by the Commonwealth and to be arguing about funding shares for arguably the nation's most important transport and freight link is disappointing," Mr Page said.

The completion of a four lane, divided Pacific Highway between Hexham and the Queensland border is a priority for the NSW Government.
