The occurrence and distribution of thoracican and acrothoracican barnacles in Australian waters are listed for the first time since Darwin (1854). The list comprises 204 species. Depth data and museum collection data (for Australian museums) are given for each species. Geographical occurrence is also listed by area and depth (littoral, neuston, sublittoral or deep). Australian contributions to the biology of Australian cimpedes are summarised in an appendix. All listings are indexed by genus and species.
