Subtropical rocky reefs are ectotonal habitats that support unique biodiversity and attract all levels of SCUBA divers. Compared to tropical corals reefs, there have been few studies evaluating the effects of SCUBA diving on these communities. Cape Byron and Solitary Islands marine parks in New South Wales include some of the most intensively dives sites in Australia, outside of the Great Barrier Reef.
This study tested variables that influence SCUBA-diver contacts, assessed risk to benthic communities, and tested levels of intervention and the use of low impact diver training, for reducing SCUBA-diver impacts.
