NON ACTIVITY DAYS - Non Activity Days were imposed by the Department of Environment, Water and Natural Resources in 2013 as a recommendation by the CSIRO (Commonwealth Scientific and Industrial Research Organisation). They are a strategy to minimise any potential impact on shark behaviour, site visitation pattern and changes to temporary residency period of sharks to Neptune Islands. 4 days per fortnight are designated as Non Activity Days and all one day operators adhere to the same schedule.

  • Climate Action Leader - We incorporate strategic climate change responses across all relevant levels of business planning and operations. We measure and audit our carbon footprint via a creditable system and have undertaken an advanced level of adaptation, emissions reduction and offsetting.
  • Flinders University's Southern Shark Ecology Group (SSEG) was awarded a Monitoring and Research contract by DEWNR for 3 years from July 2016. This research monitors the visitation patterns and temporary residency period of the sharks that we see. Information is used in the dynamic management of the Shark Cage Diving Industry to guide decisions regarding Non Activity Days. In addition to the contracted research, Flinders University excels in White Shark research and collaborates with research institutions around the world. Calypso Star Charters is a proud supporter of Dr Charlie Huveneers and his team. Charlie is a frequent guest on board our charters, tagging sharks and deploying or retrieving monitoring equipment. We provide shark images that are used in a growing ID catalogue. The high frequency of our charters assists in gaining a better understanding of the visitation patterns as some sharks only visit for a day or two each year. We are proud to pass on your donations to Flinders University to assist funding White Shark research outside of the monitoring program. READ MORE
