thumb|The spotted wobbegong is the largest wobbegong shark, reaching a length of around 3 mKuiter, p. 12. Sharks inhabit all the coastal waters and estuarine habitats of Australia's coast. There are 166 species, including 30 species of requiem shark, 32 of catshark, six of wobbegong shark, and 40 of dogfish shark. There are three species from the family Heterodontidae: the Port Jackson shark, the zebra bullhead shark and the crested bullhead shark.Kuiter, p. 8. In 2004, there were 12 unprovoked shark attacks in Australia, of which two were fatal.International Shark Attack File. 2005. SAF Statistics for the Worldwide Locations with the Highest Shark Attack Activity Since 1990 , Florida Museum of Natural History Only 3 species of shark pose a significant threat to humans: the bull shark, the tiger shark and the great white shark. Some popular beaches in Queensland and New South Wales are protected by shark netting, a method that has reduced the population of both dangerous and harmless shark species through accidental entanglement. The overfishing of sharks has also significantly reduced shark numbers in Australian waters, and several species are now endangered. A megamouth shark was found on a Perth beach in 1988;Egerton, p. 397. very little is known about this species, but this discovery may indicate the presence of the species in Australian coastal waters.
