Welcome to AUSI Snorkelling. The World's first on-line snorkel agency. AUSI Snorkelling as described by the AUSI Snorkelling Standards, offers many, internationally recognised, recreational snorkel programs.

AUSI defines three major snorkelling disciplines:

Snorkel Swimming

Snorkel Swimming is an in water activity using a mask, snorkel and fins while maintaining positive buoyancy at all times.

Snorkel Diving

Snorkel Diving is an open water breath-hold activity using a mask, snorkel and fins with the intention of going below the surface while holding your breath.

Free diving

Free Diving is breath-hold diving to depths beyond nine metres (30ft) and because of its inherent potential dangers requires specialist training.
