The long-awaited second stage of the Gold Coast light rail project will be completed in time for the 2018 Commonwealth Games, with Prime Minister Malcolm Turnbull set to commit $95 million in federal cash on Sunday.

In his first visit to Queensland since he toppled Tony Abbott as Australian prime minister, Mr Turnbull, an avid public transport user, will announce the funding for the second stage of the project, which will enable Games visitors and support staff to travel by rail from Brisbane to the main stadium.

The 7.3 kilometre route will link Helensvale train station with the northern terminus of the project's first stage at Gold Coast University Hospital in Southport.

"Construction of stage two of Gold Coast Light Rail will provide the missing link from the Gold Coast to Brisbane," Mr Turnbull said.
