There have also been suggestions to route Geelong line services via Newport into Southern Cross once again, given the crowding at Wyndham Vale and Tarneit, as well as the lack of capacity on the Regional Rail Link set of tracks between Sunshine and the city.

Announced as part of a $57.7 million package in the 2022/23 Victorian State Budget, Newport, along with other stations, will receive DDA-compliant accessibility upgrades.
