Transport for NSW is seeking feedback from road users and the community on their experiences travelling along and accessing the M1 Princes Motorway between Picton Road and the base of Mount Ousley.
The NSW and Federal Governments have jointly committed $10 million towards planning for options to improve the safety and reliability of this five-kilometre section of the M1 Princes Motorway.
Site investigations will be carried out in coming months and will be used in conjunction with community feedback to inform planning and development of upgrade options.
“The Albanese and Minns governments are committed to improving the safety, reliability and resilience of the road corridor connecting the Illawarra region and Greater Metropolitan Sydney via the M1 Princes Motorway and Picton Road / Hume Motorway,”
said Minister for the Illawarra and South Coast, Ryan Park.
“With both the construction of the Mount Ousley interchange and planning for the Picton Road upgrade well underway, we are looking at what improvements can be made to the five-kilometre stretch of the M1 Princes Motorway in between.
“Community feedback will play a vital role in the development of options to improve this stretch of road and we encourage all road users and local residents to share their experiences.”
Early investigations may include Aboriginal heritage and cultural investigations, biodiversity and environmental studies, traffic studies, surveys, and utility and geotechnical investigations.
Transport for NSW will use data gathered from early investigations and feedback received from the community to develop a number of options.
Transport will continue to keep the community informed as updates on the project are available. Transport will collate and consider the feedback received during the have your say consultation period and prepare a summary outlining what we heard by early 2026.
“Mount Ousley and Picton Road play crucial roles in passenger and freight movements in and out of the Illawarra,” said Member for Wollongong, Paul Scully.
“Over the coming years freight movements will grow and so too will the number of people travelling from south-west Sydney to the Illawarra for jobs and recreation so it is important that we understand motorists experiences when planning future upgrades.
“Over the coming months site investigations will take place to understand the existing site conditions and this will be coupled with feedback from the community to better inform the development of upgrade options.”
Feedback can be provided up until 11.59pm on Monday 20 October 2025 by visiting www.transport.nsw.gov.au/mtousleysri.
Funding for delivery of improvements will be sought after the planning is complete, the Government said in a statement.
