Killick Creek is an estuarine stream located near Crescent Head on the mid-north coast of New South Wales. It functions as a classic coastal creek system, transitioning from freshwater environments upstream to a tidal estuary that empties into the Pacific Ocean. The creek is characterized by a mix of aquatic habitats, including marine, estuarine, and freshwater zones, which support a diverse range of fish species popular with anglers. A concrete boat ramp provides access to the estuary and, during periods of low swell, can serve as a gateway to the ocean for smaller, trailered vessels.
