Resumo: 	The relationship between hard substrate type, depth and ecology has not been widely investigated in Bass Strait, which separates mainland Australia from Tasmania. As this water body is important to the State, a study along the Victorian coastline using an inexpensive Along Track Video (ATV) system, along with equipment to record depths and locations, was implemented. A better understanding of the correlation between hard substrate, depth and ecology was thought to be valuable to enable researchers to determine to what extent the benthic biological communities depend on physical factors. This understanding should improve procedures to predict the seafloor ecology on the basis of geological and oceanographic data. The dominant species assemblages and geomorphology, among other characteristics, were observed and recorded for each transect. In the sites investigated, depth appears to have a greater influence on dominant assemblages than does the type of hard substrate. The study also served to show that inexpensive ATV systems can be successfully used to study macro-sessile marine resources.
