Tide times at Koonawarra Bay Jetty (Lake Illawarra)

Sunday 25 October 2026 · Australia/Sydney

Heights and times on this page are a model estimate. The model reads the open-sea tide outside the lake's entrance, not the lake's own, so inside the lake the change comes later, the range is a fraction of the ocean's (often only a few centimetres), and wind and rain move the water more than the tide does. Use the BoM tide tables for New South Wales for this area.

Best Tide State to Fish Koonawarra Bay Jetty (Lake Illawarra)

This is still lake water rather than an entrance channel, so the tide matters less than the wind and the light. A light westerly or a calm morning is ideal, while a fresh north-easter or southerly chops the bay up and makes bite detection hard on light gear. Dawn, dusk and the change of light are the prime windows, and the flathead bite improves as the water warms from spring. After heavy rain Brooks Creek and Mullet Creek push dirty water into this end of the lake, which tends to put the bream and whiting off for a few days.

What Anglers Target Here

Anglers fishing Koonawarra Bay Jetty (Lake Illawarra) typically time sessions around the tide for yellowfin bream, dusky flathead, sand whiting, and luderick.
