A drysuit keeps a diver dry and uses an air layer for insulation, which makes it fundamentally different from a wetsuit rather than simply warmer.
That air layer is also a second buoyancy system, and learning to manage two buoyancy systems simultaneously is the core skill the course teaches. Done badly, it produces uncontrolled ascents and feet-first inversions.
For divers in Victoria, Tasmania, southern Western Australia and South Australia, a drysuit transforms winter diving from an endurance exercise into something genuinely comfortable.

Why it matters more in southern Australia
Winter water temperatures around 11–14°C in Victoria and Tasmania make repeated diving in a wetsuit genuinely limiting. Gas consumption rises when you are cold, dives get shorter, and the second dive of the day becomes unpleasant.
Exposure protection also changes weighting and buoyancy substantially, which is why local training emphasises it rather than treating it as an optional specialty.
Buy or hire first?
Drysuits are expensive and fit matters enormously. Hiring for the course and for the first several dives is sensible, and it lets you work out whether you prefer a neoprene or membrane suit before committing.
Confirm rental sizing availability before travelling, particularly in Tasmania and remote destinations where specialist sizes are not always stocked.
Common questions
Do I need a drysuit to dive in Victoria or Tasmania?
No. Many divers use 7 mm wetsuits or semi-dry suits successfully. Drysuits become more attractive for winter diving, repeat dives and longer profiles.
Is a drysuit harder to dive?
It adds a buoyancy system to manage, which is a real skill. Most divers are comfortable within a handful of dives, which is exactly what the course is for.
Neoprene or membrane?
Neoprene suits are warmer and more forgiving of undergarment choice; membrane suits are lighter, dry faster and are more adaptable across conditions. Both are common in Australia.
