Introduction To Cave Diving
Cave diving changes the way divers think.
The CDAA Basic Cave course introduces divers to overhead environment procedures, cave navigation, guideline awareness and gas management within CDAA-rated Cavern and Sinkhole environments.
Unlike open water diving, cave diving environments remove direct ascent access and require increased situational awareness, stronger communication discipline and more controlled decision-making.
The course progressively develops buoyancy control, trim, propulsion, line handling, reel procedures and team awareness while introducing divers to the procedural mindset required for overhead environment diving.
Guideline Procedures
Learn reel handling, line awareness, cookies, directional markers and guideline discipline.
Gas Management
Develop gas planning strategies appropriate for overhead environment diving.
Cave Navigation
Build awareness of navigation procedures, communication and cave team positioning.
Procedural Awareness
Improve trim, buoyancy, propulsion and situational awareness under increased task loading.
Your Basic Cave qualification: This qualification covers CDAA-rated Cavern and Sinkhole sites, subject to the rating, site access rules and conditions of training. It does not qualify you for Cave or Advanced Cave diving or unrestricted penetration.
Cave Procedures & Guideline Discipline
Cave diving relies on procedures long before problems occur.
Overhead environment diving requires stronger procedural awareness, communication discipline and situational awareness than conventional open water diving.
Within cave environments, visibility can rapidly deteriorate, navigation becomes more complex and direct ascent is no longer immediately available. Guideline procedures and team communication become fundamental safety systems.
The CDAA Basic Cave course progressively develops reel handling, line procedures, cave markers, gas strategies and communication drills designed to build more controlled and reliable cave diving habits.
Reel & Line Procedures
Develop guideline deployment, reel handling, line awareness and controlled navigation procedures within overhead environments.
Cookies & Directional Markers
Learn marker identification, directional awareness and guideline referencing procedures used during cave navigation.
Cave Communication
Build team positioning, light communication and non-verbal awareness appropriate for overhead environment diving.
Gas Management Strategies
Introduce cave gas planning principles and gas management strategies appropriate for cave and sinkhole diving environments.
Situational Awareness
Improve buoyancy, trim, propulsion and environmental awareness while managing increased task loading within cave diving environments.
Cave Training Environment
Progressive overhead environment training from Melbourne to Mount Gambier.
The CDAA Basic Cave course progressively develops overhead environment procedures, navigation awareness and guideline discipline through structured training environments beginning in Melbourne before progressing into the sinkholes and cave systems of Mount Gambier.
Melbourne Foundations
Initial training focuses on buoyancy control, trim, propulsion, reel procedures, communication drills, gas strategies and overhead environment awareness development.

Cave Equipment & Redundancy
Cave diving equipment is built around reliability, streamlining and controlled redundancy.
Overhead environment diving introduces increased task loading, restricted environments and situations where equipment failures must be managed without immediate access to direct ascent.
The CDAA Basic Cave course introduces divers to cave-oriented equipment configurations, guideline systems, lighting redundancy and gas management procedures appropriate for CDAA-rated Cavern and Sinkhole environments.
Equipment configuration within cave diving focuses on reducing entanglement risk, improving team awareness and creating more streamlined, repeatable systems capable of functioning under increased environmental stress.
Prior to training, divers are encouraged to discuss equipment suitability, sidemount or twinset configuration and cave diving goals with the team to ensure systems are appropriate for overhead environment progression.
Primary Gas Systems
Twinset or sidemount configurations appropriate for cave environments, including redundant regulators and controlled hose routing procedures.
Guideline Equipment
Reels, spools, cookies and directional markers are introduced as critical navigation and orientation systems within cave environments.
Lighting Redundancy
Primary cave lights and backup lighting systems are configured to support communication, navigation and failure management procedures.
Navigation & Wet Notes
Wet notes, cave references and navigation awareness become increasingly important within overhead environments.
Streamlining & Awareness
Cave equipment configuration emphasises reduced entanglement risk, improved trim and stronger situational awareness under task loading.
Equipment you’ll need for CDAA training: Twin cylinders with at least 3000 litres combined capacity; two first stages and two second stages, including a hose at least 2 metres long; one primary and two backup lights; and a primary reel with at least 100 metres of line. The CDAA checklist also covers exposure protection, mask and fins, a cutting device, computer, buoyancy system, tables, notes or slate, pressure gauges and a personal line marker. Review the full CDAA equipment checklist with your instructor. For equipment supply and hire, please check our course inclusions.

Your course with us: Our five-day course includes at least nine dives. Your instructor plans the Melbourne and Mount Gambier itinerary around site access.
Overhead Environment Awareness
Cave diving requires a different mindset.
Cave diving environments remove immediate direct ascent and introduce situations where awareness, communication and procedural discipline become increasingly important.
Within overhead environments, poor buoyancy control, rushed movement, loss of situational awareness or ineffective communication can rapidly increase task loading for both the individual diver and the team.
The CDAA Basic Cave course encourages divers to develop calmer, more deliberate and more disciplined diving behaviour through repeated guideline procedures, communication drills and controlled team-based cave progression.
Situational Awareness
Cave environments require continuous awareness of guideline position, team location, gas reserves and navigation references.
Procedural Discipline
Cave diving procedures rely on repetition, consistency and controlled execution under increased task loading.
Team Communication
Light signals, positioning awareness and non-verbal communication become increasingly important within overhead environments.
Controlled Movement
Trim, propulsion and precise movement help reduce silting, improve awareness and support more reliable cave navigation.
Navigation Awareness
Cave diving requires stronger focus on guideline orientation, directional references and navigation procedures.
Australian Cave Diving
Australian cave diving environments reward awareness and discipline.
South Australian sinkholes and cave systems are internationally recognised for their visibility, overhead environments and procedural cave diving culture.
Cave diving within Mount Gambier environments encourages stronger guideline awareness, more controlled propulsion, disciplined communication and improved situational awareness under overhead conditions.
The CDAA training philosophy has historically emphasised controlled progression, procedural awareness and conservative cave diving behaviour within real cave environments rather than accelerated certification pathways.
Sinkhole Environments
Mount Gambier sinkholes provide unique overhead environments for developing guideline awareness and cave navigation procedures.
Freshwater Visibility
Clear freshwater cave systems allow divers to progressively develop navigation awareness, communication and team positioning procedures.
Cave Navigation Awareness
Cave systems encourage stronger focus on directional references, line awareness and controlled movement within overhead environments.
Team-Based Procedures
Australian cave training environments reinforce calm communication, procedural discipline and more deliberate cave diving behaviour.
Prerequisites & Course Suitability
Designed for divers ready to progress into overhead environments.
The CDAA Basic Cave course is intended for divers already comfortable with buoyancy control, situational awareness and disciplined diving behaviour within more demanding underwater environments.
Cave diving progression requires calm decision-making, controlled movement and the ability to manage increasing task loading while maintaining awareness of the team, guideline and environment.
Divers entering overhead environment training should already possess reliable foundational diving skills and sufficient diving experience to safely progress into cave procedures and navigation training.
