The Albanese and Minns 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.
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.
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.
Quotes attributable to Minister for the Illawarra and the South Coast Ryan Park:
"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.
"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."
Quotes attributable to Member for Wollongong Paul Scully:
"Mount Ousley and Picton Road play crucial roles in passenger and freight movements in and out of the Illawarra.
"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."
Quotes attributable to Member for Cunningham Alison Byrnes:
"We are working hard across all levels of government to ensure that our road corridors are safer and more reliable.
"As part of this, it is vital that the community's voice is heard so that the changes we make see the best outcome for community.
"We have been listening to that feedback already as part of the Mount Ousley Interchange project, and I am pleased that the Australian and NSW governments are actively listening to the community for the ongoing work that needs to be done throughout this corridor.
"Thank you to everyone who has contributed to our work so far, and I look forward to continuing to work constructively across government and community to modernise our roads and make them safer for the future."
