Freediving is breath-hold diving pursued as a discipline in its own right, with its own training pathways, agencies and safety practices.
It is not simply snorkelling deeper. Trained freediving covers breath-hold physiology, equalisation techniques that work without a regulator, relaxation and, critically, buddy protocols for managing blackouts.
It shares water and often shares businesses with scuba, but the two are separate disciplines and a scuba centre offering freediving courses should be verified as doing so rather than assumed.

Never freedive alone
Shallow water blackout is the principal risk in freediving, and it happens without warning to fit, experienced people. A conscious diver cannot self-rescue from it.
Direct supervision by a trained buddy, one diver down at a time, is the single most important safety practice in the sport and is the reason formal training matters.
Where it intersects with this directory
Several Australian activities that people assume are scuba are actually freediving or snorkelling — whale shark and manta interactions at Ningaloo, and the Whyalla cuttlefish aggregation among them.
Freediving training makes those experiences considerably better, and it is worth considering for divers who spend time at shallow wildlife sites.
Common questions
Do I need to be a scuba diver first?
No. Freediving is a separate discipline with its own pathways, and many freedivers never take up scuba.
Can I freedive after scuba diving on the same day?
It is generally advised against, as combining the two can complicate decompression risk. Standard guidance is to freedive before scuba, not after.
Is freediving dangerous?
Freediving alone or without trained supervision is genuinely dangerous because of blackout risk. Trained freediving with proper buddy protocols has a good safety record.
