This unit applies to those working as specialist cavern divers, cavern diving adventure guides, instructors or program managers who are required to dive in caverns to a depth of 20 metres.
This unit also applies to outdoor recreation leaders working for outdoor education or adventure providers; volunteer groups; not-for-profit organisations or government agencies.

ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes of a unit of competency. | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the Evidence Guide. |
1. Plan a cavern dive. | 1.1. Access information on the site and formulate a dive plan according to relevant legislation and organisational policies and procedures. 1.2. Identify and plan for potential hazards and risks associated with the cavern dive. 1.3. Identify possible sources of stress associated with cavern diving. 1.4. Convey the dive plan to the rest of the dive team. 1.5. Establish a communication system to use with buddy and other participants while cavern diving. |
2. Select, fit and use cavern diving equipment. | 2.1. Select and fit personal equipment to avoid snagging points. 2.2. Check personal equipment for safety and serviceability according to organisational policies and procedures and manufacturer's specifications. 2.3. Identify and fit group equipment according to manufacturer's specifications. |
3. Perform cavern dives. | 3.1. Apply cavern diving techniques, demonstrating correct posture. 3.2. Demonstrate buoyancy control and anti-silting techniques. 3.3. Apply minimal impact techniques to minimise damage to the environment while cavern diving. 3.4. Use a range of cavern diving techniques to negotiate features of a water-filled cavern. 3.5. Negotiate hazards and apply strategies to reduce risk while cavern diving. 3.6. Apply buddy diving procedures and communication techniques throughout cavern dive. 3.7. Apply techniques to deal with stress where required. |
4. Use cavern diving specific navigation skills. | 4.1. Apply cavern diving navigation aids to navigate through the cavern. 4.2. Demonstrate line placement and use of a cave reel. |
5. Evaluate cavern diving activity. | 5.1. Evaluate relevant aspects of the cavern diving activity. 5.2. Identify improvements for future cavern diving experiences. |
Required skills |
problem-solving skills to: check equipment serviceability prior to use identify and negotiate potential hazards, risks and stressful situations apply cavern diving specific navigation and anti-silting techniques maintain buoyancy control planning and organising skills to: access information on cavern diving site prepare a dive plan select and fit equipment apply minimal impact techniques communication skills to: convey information regarding dive to other participants inform progress and interact with buddy through established communication systems teamwork skills to safely monitor and assist buddy throughout cavern dive SCUBA diving and swimming skills to cavern dive safely and efficiently first aid and emergency response skills appropriate to the site to enable initial response to emergencies and personal health care. |
Required knowledge |
legislation and organisational policies and procedures to enable safe conduct of all activities types and characteristics of equipment to enable selection, use and maintenance features of a water-filled caverns and safe negotiation methods factors affecting buoyancy to control sinking and floating hazards, risks and sources of stress commonly associated with cavern diving to a depth of 20 metres communication systems and buddy diving procedures suitable for cavern diving cavern diving specific navigation techniques, including line placement and use of a cave reel, to avoid getting lost under water emergency, first aid and rescue procedures appropriate to the location to ensure risk minimisation to self and group. |
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Overview of assessment | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Evidence of the following is essential: applies processes to devise a suitable dive plan and select, maintain and fit dive equipment for the specific cavern dive negotiates hazards, risks and features of a water-filled cavern, to a maximum depth of 20 metres, using various techniques, causing minimal environmental impact applies navigation techniques to move through a water-filled cavern efficiently, and communicates with and monitors buddy's progress evaluates and reflects on own cavern diving performance to identify strengths, weaknesses and areas that need improvement. |
Context of and specific resources for assessment | Assessment must ensure participation in cavern diving activities in caverns that reflect local conditions and are of sufficient breadth and duration to demonstrate competency and consistency of performance. Assessment must also ensure access to: information on the cavern dive site to plan a cavern dive and select equipment suitable locations for the conduct of cavern diving activities a suitable buddy to participate in dive process diving, safety and rescue, communication and navigation equipment. |
Method of assessment | A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit: observation of the planning and review process oral or written questioning to assess knowledge of cavern diving techniques, hazards and risks, and techniques to minimise environmental impact observation of safe participation and communication with buddy throughout diving process copy of dive plans third-party reports from a supervisor detailing performance. Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended |
