Rodd's Harbour is a significant estuarine system located on the Queensland coast within the Gladstone Regional area. It forms part of the broader Baffle catchment's northern coastal drainages, which also include Collosseum Inlet. The harbour is characterized by a network of coastal creeks, including Worthington, Pine, and Hillard creeks, flowing into the tidal waters around Rodd's Peninsula. This area is recognized as a Fish Habitat Area, indicating its importance for aquatic life. The landscape features a mix of cleared grazing land and protected natural areas, with the estuarine environment supporting seagrass habitats and tidal wetlands. As a coastal drainage system, it experiences typical estuarine conditions influenced by tidal movements and freshwater inputs from the surrounding catchment.
