Lake Illawarra

Lake Illawarra is one of the most picturesque spots on the coast. The lake has something for everyone, from parks and jetties along the foreshore to water-based activities like boating, fishing and snorkelling.

The lake provides a natural boundary between Wollongong and Shellharbour.

Care of Lake Illawarra is guided by a Coastal Management Program, or CMP. The CMP includes physical works, monitoring and investigation, and planning and education activities.

See our Lake Illawarra CMP Snapshot PDF, 1261.48 KB for an overview of the lake and what's planned for coming years.

You can also read the full CMP in the 'Planning for Lake Illawarra' section below.

We manage Lake Illawarra in partnership with Shellharbour City Council and the NSW Government.

Wollongong City Council looks after several open spaces, pathways and stormwater outlets around the lake. Shellharbour City Council looks after similar items on the southern side of the lake.

Other structures like jetties, wharves, boat ramps and the bridge are managed by the NSW Government.

Report a problem at Lake Illawarra

If you need to report a problem at Lake Illawarra, contact the relevant agency.

If you’re not sure who to contact, email or call us on (02) 4227 7111. We’ll help if we can, or point you in the right direction.

Water quality is monitored regularly at 15 sites across Lake Illawarra.

Keeping an eye on water quality gives us a picture of the overall health of the lake. It can help us identify problems and track how our efforts to look after the lake are working.

These reports also help us in planning how to manage the lake.

The most recent water quality reports can be found below.

We have developed a Coastal Management Program (CMP) PDF, 11709.17 KB for the lake in partnership with Shellharbour City Council. The CMP is a strategic program that will guide us in taking care of the lake over the next 5 to 10 years.

The CMP is supported by a number of studies and reports including:

In 2019 the draft CMP went on public exhibition and the document has been updated to address concerns and make appropriate changes. The final draft CMP was endorsed for submission to the Minister for certification by both councils in April 2020.

The draft CMP was certified by the Minister for Local Government, Shelly Hancock, on 9 November 2020. It will now go to both Wollongong City Council and Shellharbour City Council for endorsement before it is published in the NSW Gazette. We expect this to happen before the end of 2020.

Once the Plan is gazetted, we’ll start putting it into practice.

If you’d like to know more about opportunities for the community to be involved in planning for the lake, email or call us on (02) 4227 7111.

NSW Government Community Consultation on Lake Illawarra Jetties

The NSW Department of Planning, Industry and Environment (DPIE) has reviewed feedback from the community on priority upgrade work to Lake Illawarra’s public jetties.

They have announced that five jetties will undergo repair work to ensure they can be safely enjoyed by the local community. Major repairs will be made at Tuggerah Bay Jetty, Purry Burry Point Jetty, Koonawarra Bay Jetty, King Street Jetty and Old Merinda Wharf.
