Sea lions have been hunted for blubber and hide and have also been killed in large numbers because fishermen blamed them for robbing their nets.

Another possibility, says Shaughnessy, is that sea lions may be facing stronger competition for food from their cousin, the New Zealand fur seal, whose numbers are increasing on Kangaroo Island at an annual rate of around 10 percent.
Shaughnessy, recognized as an international authority on sea lions and fur seals, suggests the Australian sea lion population in 1998 may be no greater than it was before European settlement of Australia.
A female sea lion will give birth to a pup after an 18-month cycle, meaning that her pupping season occurs in alternate summers and winters, or in alternate springs and autumns.

Australian sea lions can be differentiated from these and all other southern fur seals based on coloration, lack of dense underfur, generally shorter pelage (exclusive of the mane on adult males) and vibrissae, head and muzzle shape, size of the ear pinnae, and size and shape of toes on the hindflippers.
Australian sea lions are known to prey on a wide variety of fishes (including rays and small sharks), squid, cuttlefish, and penguins.

Australian sea lions take a different approach, diving up to 100 meters down to the ocean floor to feed on a more predictable supply of bottom-dwelling organisms.
One possible explanation is that Australian sea lion pups may have a lower survival rate than fur seal pups, since they cannot handle the deep dives until they are older.
Costa equips the sea lions he studies with dive recorders that provide data on the depth and duration of each dive.

Sea lions are large, ranging from around 150 kg to over 1,500 kg, and males tend to be much larger than females (called sexual dimorphism).
Sea lions are known to battle such diseases as pneumonia, caused by a parasitic lungworm, and a bacterial infection called leptospirosis, which affects their livers and kidneys.
California sea lions are very social animals, and groups often rest closely packed together at favored haul-out sites on land, or float together on the ocean's surface in "rafts." They are sometimes seen porpoising too, or jumping out of the water, presumably to speed up their swimming.

The Southern sea lion often interferes with long line and gill net fisheries, although the extend of this interaction is unknown.
Robinson and Dennis (1988) concluded that it is very difficult to obtain an accurate estimate of the Australian sea lion population, because the colonies are scattered over remote islands.
While at sea, 2.8% of the time the seals are resting, 24% of the time is spent diving (probably feeding) and 73.2% is spent swimming.

The researchers found that the sea lions regularly stay underwater so long that their oxygen supplies dwindle to the point where they have to use anaerobic metabolism to keep swimming.
Australian and New Zealand sea lions, by contrast, seek out larger prey on the ocean floor, where they are believed to catch mainly octopus and large squids.
And since the sea lions search for a single large prey instead of many small ones, they may have an extra incentive to stay underwater beyond their aerobic limit when they spot a potential meal.
