Alicia has loved all things ocean since she was five years old, when she received a book on marine sea creatures for Christmas. She fell in love with learning about marine life and has wanted to be a Marine Biologist ever since! Alicia went on to study Marine Biology at Deakin University in Warrnambool, braving the chilly Southern Ocean waters, but it was a study abroad exchange to Hawaii that she really fell in love with tropical environments, especially the importance of coral reef systems. Alicia completed her Honours in Marine Science at Murdoch University in Perth, and from her research she found how important marine interpretation and education was for the general public.

Alicia has been working on the Great Barrier Reef for Quicksilver Cruises since 2019, and she really enjoys talking to the various visitors that come to the reef. She finds that no matter how far or wide people have travelled, people really do want to learn more about the health and state of the reef and she takes great pride and joy in educating and informing everyone that passes through her tour on the importance of the reef, and how they can make a difference.

Benny Howard – Master Reef Guide | Senior Eco Host | Ocean Safari/Ocean Rafting | Cape Tribulation/Whitsundays (Cohort 7)

Benny grew up on a farm on Kangaroo Island in South Australia and has always had a huge passion for wildlife and conservation. To start a career in this area he joined programs such as tracking endangered glossy black cockatoos and building nest boxes, and land care tree planting. Being surrounded by the Southern Ocean also gave him the opportunity to work closely with national parks at the Seal Bay conservation park introducing guests to the local Fur Seal population and played a role in the Fairy Penguin eco management program. 

His biggest passion by far has always been in and around the ocean with a dream to one day visit and continue this career path within the world heritage listed great barrier reef. For the last two and a half years he has been part of the team at Ocean Safari in Cape Tribulation/ Daintree Rainforest and also with Ocean Rafting in the Whitsundays.

Benny loves representing these incredible regions by showcasing the fringing reefs, outer reefs, amazing beaches and islands and the importance of understanding the amazing indigenous cultures. Giving them a unique, enjoyable and learned experience.

He enjoys connecting with his guests in a fun and engaging manner to inspire them to learn more about what they can do to make a difference in their daily lives.

“I believe awareness is the key and knowledge is power. We can’t ask people to look after something if they don’t appreciate or understand it, and love it as much as I do.”

Originally a Kiwi, Master Reef Guide Brooke moved to Australia in 2011 to Daydream Island. She would watch as fast little yellow boats drove past, full of excited guests off on a day of exploring nature and the underwater world of the Great Barrier Reef. Sometimes the boats would stop into the island to pick up and drop off guests. This was Ocean Rafting, and better yet on one particular day Brooke quickly realised there were two females, one at the helm and the other guiding the guests. Fast forward a couple of years and with no marine or boating experience, Brooke became an eco host with Ocean Rafting in the Whitsundays. She then discovered Ocean Rafting had a sister company in Cape Tribulation - Ocean Safari. Brooke visited the Daintree Rainforest and Mackay Reef for the first time in late 2014, by June 2015 she was their newest Eco Host and she never looked back. Over 8 years on and Mackay Reef is without a doubt her favourite place to be. Brooke is proud to be an Eco Host and Skipper for Ocean Safari Cape Tribulation, educating guests while having fun in nature with a majority female crew. "I will always appreciate the time past and present crew and industry friends have given me, these are the people that helped build my passion and lay the foundations to better understand the Great Barrier Reef. Becoming a Master Reef Guide has deepened and refined that same passion and knowledge so I can share this World Heritage Listed Area in great detail with guests from all walks of life. I also find it very rewarding sharing my learnings from the Master Reef Guide program with new and emerging industry crew, helping them develop and fine tune their own guiding skill set and knowledge base."

Hayley fell in love with the Great Barrier Reef at the young age of seven. Her first visit to the Great Barrier Reef was on board Quicksilver Cruise’s in Port Douglas.  This sparked overwhelming emotions leaving her with an unforgettable ‘mermaid like’ buzz. Growing up the feeling never left; inspiring Hayley to complete a Masters Degree in Marine Biology and become a published scientist.

Hayley has worked on the Great Barrier Reef as a researcher and surveyor for the Australian Institute of Marine Science, the Great Barrier Reef Park Authority and James Cook University. Since 2019, she has combined her love of performing and the Reef to become a full-time mermaid with Quicksilver Cruises, travelling to Quicksilver’s Pontoon and Low Isles off Port Douglas.

“Every day, I am still amazed by the Reefs natural beauty. Every day, I am still curious to learn more. The mermaid-buzz never disappears when your office is the Great Barrier Reef World Heritage Area. It is an incredible honour to become a Master Reef Guide and be surrounded by the ultimate brain trust for the Great Barrier Reef! Being a Master Reef Guide with Quicksilver will allow me to continue to share my passion and curiosity for the Reef, furthermore inspire and educate a wide demographic of people.”

Since then he has developed as a dive professional, travelling around the Indo- Pacific region in Australia, Indonesia and New Zealand before returning to his roots on the Great Barrier Reef to stay!

“This is the first time in a long time that I have finally felt as though I have met people who really care about the same things as I do and that I am no longer alone in trying to put forward my beliefs about the world and particularly the ocean. I am proud to represent something that I believe in so strongly and am more motivated to do so.”

Tahn Miller – Master Reef Guide | Dive Instructor | Wavelength Reef Cruises | Far North (Cohort 5)

Tahn’s story starts in a small coastal town in New South Wales called Crescent Head, and then later Hat Head, Kempsey.



Like many children from Kempsey, Christmas meant a caravan holiday to the beach. Sometimes for a week; other times, if we were lucky, three weeks. It was an age of wonder and discovery!



Fast forward 20 years and Tahn is on the Great Barrier Reef for the first time, just about to do his first scuba dive in open water. “I remember my anticipation; I see the same look in the faces of the guests on the outward journey.  As soon as I put my face underwater, my life was completely changed, my world view shifted, and I was that little boy again looking for hiding invertebrates and gifts of other unknown things.”

That week changed Tahn’s entire life, he has never since left the Great Barrier Reef...in fact, and he did not even catch his return flight.  That was 10 years ago and he continues his work on the Great Barrier Reef to this day.

“The Great Barrier Reef is such a spectacular place and I absolutely love to see people connecting to it just like I did on my first day. It reminds me daily of just how lucky we are to be able to walk and swim on this Earth.”

Kelly Rawding – Master Reef Guide | Biologist & Guide | Sailaway Port Douglas | Far North (Cohort 7)

From a young age, Kelly has always been fascinated by the underwater world. The more documentaries she watched, aquariums she visited, books she read, she knew in her past life she was most definitely a fish. As she completed her bachelor’s in marine biology, she realised administration life just wasn’t going to cut it- she was a fish at heart after all. So, she embarked on finding a way to always be in the ocean. She entered the marine tourism industry on a dive master internship on Moreton Island and realised, this was how she would live this life as a fish.

After completing her dive masters and university degree, she applied for a position as Marine Biologist/Deckhand/Snorkel Guide on the beautiful sailing catamarans of Sailaway in Port Douglas.

"It was love at first sight: Port Douglas, the sailing and most importantly the stunning reef at Low Isles and Mackay Coral Cay!"
