Where Does the Australian Sea Lion Live?
The Australian Sea Lion is a rare endemic species found exclusively along the southern and western coasts of Australia. Their range spans from the Houtman Abrolhos islands in Western Australia to the Pages Islands east of Kangaroo Island in South Australia. They are typically restricted to the continental shelf, rarely venturing into deep oceanic waters or far from their established breeding colonies.

Behavior
The Australian Sea Lion is a charismatic and highly social pinniped, though it is notably more sedentary than other seal species. They are non-migratory, meaning they tend to stay close to their natal colonies throughout their lives. On land, they spend a significant amount of time resting on sandy beaches or tucked away in coastal scrub to regulate their body temperature. Despite their bulky appearance, they are surprisingly mobile on land, using their powerful front flippers to prop themselves up and 'walk' across the sand.
In the water, these sea lions are agile 'benthic' hunters, meaning they forage primarily along the sea floor. Their social structure is complex, particularly due to their unique aseasonal breeding cycle, which can last up to 18 months. This leads to high levels of territoriality among bulls (males) who will aggressively guard 'harems' of females. While they are often curious toward humans in the water, they are wild animals that require significant space on land to avoid stress or defensive behavior.

Camera Tips
For those lucky enough to live near a coastal haul-out site, camera placement is key. Position your camera on a stable, salt-resistant tripod or mount at a height of about 3 feet. Angle the lens toward the high-tide mark where sea lions often congregate to avoid the damp sand. Because salt spray can quickly cloud a lens, we recommend using a protective housing with a hydrophobic coating or checking the equipment frequently to wipe down the glass with a specialized lens cloth.
Set your camera to trigger on medium sensitivity; sea lions are large and easy for PIR sensors to detect, but wind-blown beach debris can cause false triggers. Using video mode is highly recommended over stills, as it captures the unique 'waddling' gait and social interactions like billing or pup-rearing that make this species so special. A 20-second clip is usually enough to capture a meaningful behavior without draining the battery too quickly.
Since these animals are Endangered and protected by law, never approach them to set up a camera. Use a telephoto lens or place cameras in areas where sea lions are known to pass through, ensuring you maintain the legal distance required by local wildlife authorities. The best lighting occurs during the 'golden hours' of early morning, which highlights the contrast between the males' dark fur and their distinctive yellow manes.
