One Tree Island - Diving Policy and Information


All SCUBA diving at One Tree island must be conducted according to the AS/NZS 2299.2:2000 and the University of Sydney SCUBA Diving Operations ManualMicrosoft Word document. All visitors will be asked to read this manual and sign that they have done so.

One Tree Island Research Station is not responsible for supervising diving operations at One Tree Island. The resident Safety Officer the Station Manager has the final say as to whether boats can be used with respect to weather, tide and other conditions.

All researchers who choose to dive at One Tree Island must do so with the approval of their home institutional Diving Safety Officer (DSO) and provide supporting documentation (Appendix A - Dive Register). One member of every team must be approved to be the Dive Coordinator by their resident DSO and provide supporting documentation. Dive coordinators will be responsible for the diving activity of their dive teams and must be present at all team dives.

Dive Proposals must be prepared using the standard form (Appendix B) with documentation of risk assessment (Appendix D) and approved by the home institution DSO. When planning repetitive dives at One Tree Island note that the reduced bottom time limits for remote locations, over 6 hours from a decompression chamber, apply (Appendix F). A copy of all approved Dive Plans and diver registration should also be sent to Heather Sowden the DSO at the University of Sydney. A copy of each approved Dive Proposal will also be kept on file at OTIRS.

All researchers from Australian and New Zealand institutions should be diving according to the standard (AS/NZS 2299.2:2000). It is clear however that not all institutions currently have a DSO. Dive teams from institutions not following the standard will need to go through a check out procedure with the Usyd diving officer.

Dive teams from outside of Australia will dive under the authority of the University of Sydney and may need to go through a check out procedure with the USyd diving officer. Many overseas divers have scientific diving qualifications which are at the standard (i.e. American Academy of Underwater Scientists). All reciprocity for overseas researches will be granted through the USyd diving officer.

In line with AS/NZS 2299.2:2000 and University of Sydney Diving Operations all researchers will need:

  1. Appropriate SCUBA certification, as approved by home institution DSO
  2. Commercial diving medical within the past 12 months
  3. Current Oxygen Therapy Certificate
  4. Current First Aid/CPR Certificate

Divers will also need to sign a form stating that your dive gear, BCD, Regulators, Gauges and Metering equipment has been serviced by a qualified person within the last 12 months. Bring certificates of service if you have them.

Evidence of emergency evacuation insurance will also be asked for. OTIRS will not cover the cost of evacuation. It is highly recommended that all visitors have medical travel insurance such as that offered by the Divers Alert Network (DAN). See also the OTIRS booking form.


OTIRS provides tanks, weight belts and weights. Visitors need to bring all other diving equipment with them.

OTIRS aims for all visitors to have a productive and enjoyable stay at One Tree Island.
