Wreck Diver covers the specific hazards and techniques of diving shipwrecks: navigation around large structures, entanglement risk, sharp metal, silt and the disorientation that a complex structure produces.
The most important distinction the course draws is between swimming around a wreck and entering it. These are genuinely different activities with different training, equipment and risk profiles.
Australia has exceptional wreck diving — the SS Yongala, HMAS Canberra, the ex-HMAS Brisbane, HMAS Swan, the Ships' Graveyard and Darwin's WWII losses — which makes this one of the more practically useful specialties here.

External touring versus penetration
Swimming around a wreck and penetrating enclosed spaces are not the same activity. A general wreck dive should not be confused with technical wreck penetration.
Recreational wreck courses typically cover limited penetration within the light zone, with a continuous guideline. Full technical wreck training deals with genuine overhead environments and is a separate discipline.
Australian wrecks are often protected
Many Australian wrecks are protected historic sites, and some — such as the SS Yongala — are also gravesites where penetration is prohibited entirely.
Nothing may be removed from a protected wreck. Understanding the legal status of a site is part of diving it properly.
Common questions
Can I penetrate a wreck after this course?
Recreational wreck training typically covers limited penetration within the light zone using a guideline. Deeper or more complex penetration requires technical wreck training.
Do I need special equipment?
A cutting tool, a good light and a reel are standard. Penetration diving adds redundancy requirements that recreational configurations generally do not meet.
Which Australian wreck should I start with?
The ex-HMAS Brisbane and HMAS Swan were both prepared specifically for diving, which makes them more forgiving introductions than historic losses.
