Worldwide. Coastal areas of mainland Australia and Tasmania.
Observed along the shores of saltwater lakes, coastal bays, inlets and intertidal shorelines. The Ruddy Turnstone's diet includes invertebrates such as insects, crustaceans, molluscs and worms, as well as carrion, eggs and plant material.
This species can be observed flipping over stones and other objects to get at prey items hiding underneath; this behaviour is the origin of the name "turnstone". It usually forages in flocks.
