Protection of the Marine Environment

Jetty Dive Centre are certified in Advanced Ecotourism through Ecotourism Australia, and members of Green Fins. We prioritise the protection of the Marine Environment we live and work in. When diving with Jetty Dive:

  • You will not to touch or remove anything underwater (with the exception of trash or rubbish, that has not inegrated into marine ecosystem)
  • You will not feed the fish or any marine life
  • You will not leave any rubbish, trash, or waste on the boat or in the sea
  • You will not chase, harass or excessively use strobes / flash on any marine life.
  • You will not use muck sticks, reef pointers, reef hooks, tank bangers, or shark deterents.
  • You will maintain good buoyancy and stay clear of the reef at all times to prevent damage.
  • You will allow your dive / snorkel guide or other staff member to correct any damaging behaviour you exhibit towards marine life or the marine environment.
  • Remember – Take only pictures and leave only bubbles.

Sanctuary Zones

Sanctuary Zones within the Solitary Islands Marine Park (SIMP)  are ‘no take, no touch’ zones.

  • The majority of the dive sites within the SIMP afford the highest level of marine protection within Australia -“Sanctuary Zones“, which provide protection for all marine animals, plants, and their habitat.
  • This zone allows ‘passive low-impact’ activities such as diving and snorkelling and excludes commercial and recreational fishing.
  • Sanctuary Zones within the SIMP are recognised as the most sensitive and ecologically important areas due to the occurrence of fragile life form, including hard corals, and many threatened marine species.
  • Accordingly, it is mandatory to take all possible steps to minimise/eliminate; incidental diver contact with the sea life, and negative interactions with threatened species such as the grey nurse shark, black cod and other fish species.

Incidental contact results in accidental damage of hard corals, dislodging of algae, sponge, urchins and ascidians and abrasion of soft corals and anemones.

How to avoid incidental contact:

  • Ensure that all diving equipment is adequately clipped to your BCD to eliminate contact and snagging with the bottom and/or marine life (rental equipment features clips/holders to do so).
  • Maintain neutral buoyancy and a horizontal streamlined body position above the bottom.

Grey Nurse Shark and threatened marine species encounters;

  • Do not chase, harass, touch or interrupt normal swimming behaviour of threatened marine species.
  • View sharks from the side at the same depth or below the animal.
  • Limit the release of large amounts of bubbles, which can spook sharks.
  • No use of tank bangers or shark deterrants, as it disrupts the behaviour of Grey Nurse Sharks.

Reef-Safe Sunscreen Policy

Chemicals in sunscreens can be damaging to the marine ecosystem. According the the National Ocean Service Website, algae, urchins, fish, shellfish, and even marine mammals can be affected by the chemicals in sunscreen. For this reason we have adopted a ‘Reef-Safe Sunscreen Only” policy for our trips. If you will be getting in the water, please ensure you wear only reef-safe sunscreen. For more guidance, and to check your sunscreen, please read our post about our Reef-Safe Sunscreen Policy.
