Home to more than a third of the population, New South Wales is the centre of Australia’s infrastructure boom, attracting the largest share of investment.

Here are all the current and prospective NSW projects determined by Infrastructure Australia to be of the highest priority for investment.

High priority projects

These projects address a significant challenge facing local residents now or in the future. They are:

  1. Sydney Metro: City & Southwest

The Sydney Metro is Australia’s largest public transport project and is already under construction. Stage 1 – Sydney Metro Northwest – is scheduled to complete next year, but it’s Stage 2 of the project that will have the biggest impact. Due to complete in 2024, the City & Southwest extension will ease urban congestion and reduce travel times in the city centre.

  1. M4 Smart Motorway

The NSW Government has committed $470 million to upgrading the motorway between Parramatta and Lapstone with smart technologies. These will collect and display real-time information to improve safety and convenience for motorists in Western Sydney.

  1. WestConnex

The 33-kilometre motorway between North Strathfield and Arncliffe will ease road congestion in the inner west as Sydney’s population continues to grow in the decades ahead. Construction costs were estimated at $16.8 billion, but when other expenses are included, the total may exceed $45 billion.

  1. Western Sydney Airport

Sydney’s second airport will begin construction later this year at Badgerys Creek. Western Sydney Airport is scheduled to open in 2026, with capacity for 10 million annual passengers and large aircraft. The airport is expected to cost $5.3 billion, with investment also needed for road and rail connections.

Priority projects

Less critical, but still beneficial for communities and the economy, these infrastructure solutions have also been positively assessed:

  1. The Northern Road upgrade

The most urgent part of the government’s 10-year Western Sydney Infrastructure Plan, upgrades to 35km of The Northern Road will add extra lanes to increase the road’s capacity and safety. It will also connect to the new Western Sydney Airport.

  1. Bringelly Road upgrade, stage 2

Also part of the $3.6 billion Western Sydney Infrastructure Plan, the Bringelly Road upgrade affects 4.3km of the road between King Street in Rossmore and The Northern Road at Bringelly. These upgrades include designated turning lanes at traffic lights, a pedestrian and cyclist path, bus bays and new intersections.

High priority initiatives

A number of promising projects are under consideration, but still require a full business case to be made. They include:

  • Sydney Gateway – connecting the WestConnex motorway to Sydney Airport and Port Botany.
  • Bus Rapid Transport – easing congestion in the Northern Beaches, Parramatta Road and Victoria Road.
  • Southern Sydney to CBD public transport enhancement – connecting the CBD to the inner south urban growth area.
  • Sydney Metro West – an extension of the Sydney Metro between the CBD and Parramatta, expected to cost up to $15 billion.
  • Port Botany freight rail duplication – increasing rail freight capacity as Port Botany becomes Australia’s largest container port in the next few decades.
