Research & Discovery
Coastal Tours


RADKI offers guests a rare insight into the largely unexplored North Western coastline of Kangaroo Island. By being on board our customised 8 meter Zodiac rib RADIKAL, you will witness some of South Australia's most vulnerable yet iconic marine and coastal species up close and personal.

RADKI holds a South Australian MARINE MAMMALS INTERACTION PERMIT to swim or dive with the endangered Australian Sea Lion, the Long Nosed Fur Seal, and three species of bottlenose and common dolphins.

Our tours are for those passionate about the marine environment. Join us for a unique experience as a Marine Citizen Scientist where you will actively contribute to increasing knowledge, awareness and improving conservation efforts for this volatile marine and coastal environment. Or just sit back and enjoy the wild world of Australia's temperate Great Southern Reef.


With years of experience as tour guides, Ro and Phil bring an expertise to RADKI tours that is beyond expectations.


We specialise in educational and environmental discovery tours along the North Coast of Kangaroo Island.


There is so much to see and discover along the unspoilt coast lines of Kangaroo Island. Check out our gallery!

We would love to hear from you and have a chat about how we can get you onboard. 


Stories from RADKI Guests

Best marine tour company on Kangaroo Island with a great team of people, I would highly recommend.

If you're looking for a unique adventure, showing you the best of the wildlife and wild coast of Kangaroo Island, then I could not recommend Ro & Phil more highly. With so much experience and passion, it's an unforgettable experience with the chance to see so many amazing animals, but also to learn about them and maybe even contribute to research that will help protect them. Get out there and get exploring on Radikal!!
