Scuba Diving in Port Lincoln
Shark cage tourism, sea lion swims and offshore island diving — categories that need separating.
Port Lincoln is internationally associated with shark-cage tourism, and it is the only place in Australia where great white shark cage experiences operate.
However, shark-cage operations should be classified separately from normal scuba centres. They are wildlife tourism operations, and the activity is typically surface-supplied or snorkel-based rather than certified scuba diving.
The region also offers genuine scuba diving — offshore islands, sea lion colonies and reef systems — along with sea lion swims that are among the most engaging wildlife interactions in Australian waters.
