Lake Cooroibah is a scenic lake nestled within the greater Noosa River estuary system in Queensland, Australia. Functioning as a key link in this expansive estuarine network, Cooroibah sits between Lake Doonella to the south and Lake Cootharaba to the north, connected by stretches of snag-laden river banks that are as productive as the lake itself. The lake is characterized by shallow sandbanks, a deep hole at its northern end, and an uneven rocky bottom at its southern end, making it a diverse and rewarding fishery for a wide range of species. The channel running through the lake adds further structural variety, and the entire system is influenced by tidal movement, which plays a significant role in fish behavior and feeding activity.
