Snorkelling is an activity in which a person swims using a mask, snorkel and swimming aids such as fins, but without using self-contained underwater breathing apparatus (SCUBA).
Snorkelling includes both snorkel swimming and snorkel diving. Snorkel swimming is snorkelling on the surface of the water. Snorkel diving however, includes breath-hold diving and swimming below the surface.
Note: ‘Snorkelling’ does not include activities in a swimming teaching program where masks and snorkels may be used incidentally as part of the program.
