Mandagery Creek is a stream flowing through the Cabonne region of New South Wales, Australia, within the broader Murray-Darling Basin system. This waterway holds genuine ecological significance, supporting a range of native fish species as well as several threatened and endangered aquatic animals. The creek is an unregulated river system, meaning its flows are largely natural and subject to seasonal variation, which directly influences fishing conditions throughout the year. The lower reaches of the creek are particularly notable for their high instream values and biodiversity, making it a rewarding destination for anglers seeking native Australian species in a relatively natural setting.
