Fishing in Ku-ring-gai Chase National Park

Ku-ring-gai Chase National Park sits on Sydney's northern fringe, about 40 minutes from the CBD, where a network of tidal creeks and drowned river valleys push deep into sandstone bushland before opening out toward Broken Bay and the Hawkesbury.

The water here is estuarine — mangrove-lined, tidal, and connected to the ocean — which shapes both the species available and how you fish for them. Cowan Creek is the park's main waterway and the one most anglers orient around.

It runs for a considerable distance through the park, with Bobbin Head sitting at its upper reach and providing the most accessible entry point — sealed roads, parking, and a marina at Appletree Bay nearby.

Coal and Candle Creek feeds into the system further north, and McCarrs Creek enters from the west, reached via McCarrs Creek Road through Terrey Hills.

These are tidal arms, not freshwater streams, and they fish accordingly: bream, flathead, and luderick are the species most commonly associated with this kind of country in the Sydney basin.

Akuna Bay, accessible via Liberator General San Martin Drive off McCarrs Creek Road, gives another launch point into the broader creek system.

The Basin, on Pittwater, is only reachable by ferry or on foot — no road access — which keeps pressure lower on the water around it. Fishing is permitted in the park, and the standard NSW recreational fishing rules apply.

Check current conditions and any specific park requirements with NSW National Parks before you go, as rules in protected areas can change.

What makes fishing here different from the open estuary is the setting itself — the creeks are narrow, heavily vegetated, and the tidal movement concentrates fish in predictable ways around structure and mangrove edges.

You're fishing inside a heritage-listed park, and that comes with responsibility. Take what the rules allow, handle fish carefully, and leave the water the way you found it.
