What You Can Expect

Green Island Day Trip from Cairns Including Seawalker Helmet Dive

Green Island

Check in at the centrally located Reef Fleet Terminal in the morning to confirm the time of your Seawalker Helmet Dive. Then board a high-speed catamaran for Green Island, located just 15 nautical miles (27 km) offshore from Cairns.
The coral cay of Green Island, covered by lush rainforest and sandy white beaches, comprises both a national park and marine park and is part of the Great Barrier Reef World Heritage Area — home to sea anemones, stingrays, giant clams, and green and hawksbill sea turtles.
Morning tea or coffee is served on board, while beverages are available for purchase all day from the licensed bar (own expense). In the afternoon, enjoy a buffet lunch, if option selected.
On arrival, your crew provides snorkeling instruction and suggests a variety of included activities in addition to the Seawalker Helmet Dive. You can take a glass-bottom boat tour, snorkeling tour or a guided rainforest walk.
At your allotted time, your guide accompanies you on the 45- to 60-minute Seawalker Helmet Dive — perfect for non-swimmers or anyone who might not be confident in the water. Your head stays dry in the helmet, allowing you to wear glasses or contacts and keep your hair dry. Suit up and get comfortable with the provided equipment, then take a walk on the sea floor of the Great Barrier Reef for a close-up look at vibrantly colored fish and coral.
Back on dry land, make use of the shower, restrooms and changing room facilities at the Green Island Resort. Canoes, sailboards, surf skis, beach chair and umbrellas are also available to rent before you’re returned to Cairns at the end of the day.

What a fantastic and enjoyable day. Everything was on time, we has our Seawalker Dive, confirmed for later in day OK and Green Island is enjoyed from the north of island, stay away from the main beech tourist area's walk to north beech. You will not be let down. WOW.

Boat over is to Green Island is fun. Once there, it's small enough to walk about and see the sites. The actual Seawalker experience was amazing. We don't scuba dive so this is the closest you'll get. I had some trouble getting my ears to pressurize, but they kept helping me. Once down on the sea floor, it was so much fun to have the fish swim right by your helmet. Wish we could have stayed down longer. Highly recommend as a must do.

I highly recommend this trip. My husband and I got a kick out of being under the water with fish and reef. If your looking to experience the reef under the water and you are hesitant about scuba, this is a really good alternative. Overall they were very pleasant and provided an one of kind experience.

The experience was amazing, just wish it was for a little longer. The operators worked like clockwork, very well organised and professional. Crew members under water were FANTASTIC! THANK YOU for making me feel safe!!!
For me and my husband 58 and 59 this was the experience of a lifetime!!!

This was the most awesome experience ever, it beats swimming with the dolphins. And being a Jon-swimmer, perfect for me. The guides were really good and we were that close to the fish, we could touch them.

This was the experience of a lifetime! I am not fond of the water and rarely swim, so this helmet dive was perfect for me! I didn't even get my hair wet! They put this heavy helmet on my head, but when I was under the water, it wasn't heavy at all! There were fish all around me and I even got photo bombed by the resident Parrotfish! It was perfect!!!

Worth the experience. The pictures and video of the experience on the other hand cost entirely too much.
