Booking in advance helps secure better deals, especially during peak seasons. Many dive operators provide equipment rental, but bringing personal gear can be beneficial.

Health and Safety Considerations

Health and safety are paramount when diving in Australia. Ensure you’re in good physical condition and have recent dive certifications. Plan for travel insurance that covers scuba diving.

Screenings for decompression sickness and adherence to dive tables are critical. In places like Agincourt Reef and sites around Sydney, currents can be strong, so diving with a buddy is recommended.

Be aware of marine life, such as Grey Nurse Sharks. These creatures are generally non-threatening but should be respected. Pack a comprehensive first aid kit and understand basic emergency procedures.
