Grey Nures Shark Projects
Grey Nurse Shark Watch
To assess the population of the grey nurse shark in south east queensland, Queensland Parks and Wildlife Services is asking the help of the community to help count the number of grey nurse sharks. Where custodian of specific dive sites will help count the grey nurse sharks once or twice a year.
UniDive is custodian of Wolf Rock at Double Island Point and of Flat Rock at Point Look Out.

Past Projects by UniDive in 2003
Mapping the habitats of the critical
endangered Grey Nurse Shark in
South East Queensland
- funded by Threatened Species Network in 2003

Little is known about Grey Nurse Shark critical habitats or why they select particular sites to aggregate. This project has addressed part of this deficiency by mapping critical habitats, gathering species inventories and developing protocols for ecological monitoring of critical habitats in southern Queensland, thus assisting stakeholders to define and effectively manage these critical habitats. In 2002 members of UniDive applied successfully for World Wide Fund for Nature, Threatened Species Network funds to map the critical Grey Nurse Shark Habitats in south east Queensland.
UniDive members used the funding to survey, from the boats of local dive operators, Wolf Rock at Double Island Point, Gotham, Cherub's Cave, Henderson's Rock and China Wall at North Moreton and Flat Rock at Point Look Out during 2002 and 2003. These sites are situated along the south east Queensland coast and are known to be key Grey Nurse Shark aggregation sites.
During the project UniDive members were trained in mapping and survey techniques that include identification of fishes, invertebrates and substrate types. Training was conducted by experts from the University of Queensland (Centre of Marine Studies, Biophysical Remote Sensing) and the Queensland Parks and Wildlife Service who are also unidive members. The monitoring methods (see methods) are based upon results of the Unidive Coastcare project from 2002, the international established Reef Check program and research conducted by Biophysical Remote Sensing and the Centre of Marine Studies.
The outcomes (see results) of the project are helping the community; environmental managers and scientist to better understand and effectively manage grey nurse sharks and their critical habitats in southeast Queensland. In addition, maps of each of the critical habitats were developed and are available on the web for the dive community and other interested parties. It is intended that these maps will assist with more accurate recordings of grey nurse shark sightings and underwater navigation around these popular dive sites.
For further information contact the volunteer project coordinators: Chris Roelfsema (email@example.com)
The methods for conducting the surveys are derived from projects conducted by the Centre of Marine Studies and Biophysical Remote Sensing Group at UQ, Reef Check and the UniDive Coastcare project. The methods are described in the methods manual (Methods Manual).
Volunteers were trained at regular gatherings where experts present easy to understand techniques for surveying and identification of marine life at the project locations.
All dives were conducted from either MV Esperance Star (Trevor Jackson)for North Moreton Sites or Point Look Out SCUBA (Ken Holzheimer)for Flat Rock and Wolf Rock.
Quality assurance of data collection was established by testing the volunteers using tests (knowledge quizes) and by replicating transect data within the field.
