Aerial of Shallow Estuary and Navigation Channel, Mandurah, Western Australia

A sweeping aerial view of a calm estuary where pale green sand flats transition into deeper blue water. A dark, straight navigation channel leads from a small boat ramp and twin jetties into the bay, marked by posts along the way. Patchy seagrass beds and sandbanks pattern the foreground, while a curved suburban shoreline and tree-lined reserves frame the scene under a clear sky.
