Mooney Mooney Creek is a tidal stream located on the Central Coast of New South Wales, Australia, flowing into the Hawkesbury River system. It is characterized by shallow, brackish waters with extensive oyster beds and a network of small inlets and side creeks, creating a diverse estuarine environment. The area around the creek includes the small waterfront village of Mooney Mooney and features two islands, Peat Island and another unnamed island. The creek's lower section is influenced by a dam structure, and the surrounding landscape offers a mix of accessible banks and more remote areas ideal for exploration by small craft.
