Night diving is the cheapest way to double the number of dive sites available to you, because a site you know well becomes genuinely unfamiliar after dark.
The marine life changes completely. Octopus and cuttlefish become active, crustaceans emerge, parrotfish sleep in mucus cocoons, and coral polyps extend to feed.
The course covers light management, communication by torch signal, navigation without visual references and the specific disorientation risks of diving in the dark.

Australia's best night diving is under jetties
Edithburgh, Blairgowrie, Rye and Busselton are all substantially better after dark, and several of them are internationally known primarily as night dives.
Shallow depth, easy shore access and dense invertebrate life make jetty sites almost ideal for night diving — long, relaxed dives with constant activity.
Always carry a backup light
A primary light failure at night without a backup turns a pleasant dive into a genuine problem, particularly under a structure.
Two lights is the minimum standard, and a third is common among divers who night dive regularly.
Common questions
Is night diving more dangerous?
It adds disorientation and navigation challenges, which is why the training exists. With adequate lights, a known site and a buddy, it is a straightforward extension of normal diving.
What light do I need?
A reliable primary light with reasonable burn time, plus at least one backup. A marker light on the cylinder or SMB helps buddies stay together.
Where is the best night diving in Australia?
The southern jetties — Edithburgh, Blairgowrie, Rye and Busselton — are outstanding, with dense invertebrate and cephalopod activity after dark.
