The NSW Government has laid out the state's infrastructure strategy for the next 20 years.

Every five years, the State Government outlines key infrastructure.

This time round, the Western Harbour Tunnel, Beaches Link, F6 extension, Sydney Metro West and North-South rail link in western Sydney top the list.

The strategy includes plans to trial demand-based ferry services in Sydney Harbour and upgrade public transport on Parramatta and Victoria Roads.

The NSW Government has also pledged to improve rail services along the Richmond line, explore setting up a link between Hurstville and Macquarie Park via Rhodes and connecting greater Parramatta with Epping and Kogarah.

The Premier says the government will deliver.

“Of the more than 700 projects linked to the 2012 plan, over 430 are complete, 200 are under construction and the rest are in the planning stage,” she said.
