One of the predators of the Australian sea lion is the great white shark (Carcharodon carcharias), especially near the Dangerous Reef region of the Port Lincoln area (Riedman, 1990). Fishermen also occasionally kill them accidentally by entangling them in their nets (World Conservation Monitoring Centre, 2000). Historically, the population was greatly reduced due to sealing (Jefferson, 1993).
