This paper continues previous ecological studies (Dakin, Bennett, and Pope 1948) of the intertidal zone of south-eastern Australia. The environmental factors and the zonation of the animals and plants on the exposed rocky coasts of Victoria are described. As a result of this survey a rearrangement of the biogeographical provinces of the Australian littoral is made, and a new Cool-temperate fauna and flora are recognized on the coast of Victoria.

The environmental factors and the zonation of the plants and animals on the exposed rocky coasts of Tasmania are described, and the findings of the present survey are compared with those of other workers both in Tasmania and in southeast Australia generally. A distinct biota, traces of which were first noticed in Victoria by the present authors (1963), is evident on Tasmanian shores, and the validity of the authors' cool temperate Maugean Province is reaffirmed. This paper concludes the series of ecological studies (Dakin, Bennett, and Pope 1948; Bennett and Pope 1953) on the intertidal zone of south-eastern Australia.
