The shallow waters provide some of the best snorkelling in the world, brimming full of funny and stunning marine life. 

Certified scuba diving
This trip is designed to cater to divers who want to explore the Outer Great Barrier Reef during a day trip. Poseidon offers our guests large tanks and computers to increase your time in the water, as well as guided tours every time! You'll get to do drift dives and wall dives for an immersive experience, and check out isolated pinnacles and the abundant amounts of fish surrounding you! Divers are able to experience up to three different dives at three different sights for a diverse and phenomenal reef experience. Divers must be at least 12 years old, and we ask that all certified divers bring alone their certification card. 

Introductory scuba diving
There is no experience required to enjoy the thrill of scuba diving with the added bonus of an introductory dive! Under the careful supervision of our dive team, you will get to experience what it's like down beneath the surface, immersing yourself into the reef! You can try this fun activity 1, 2 or 3 times, depending on how much you're enjoying yourself and experience 3 different reef environments.

Dwarf Minke Whales
Between the months of May and August, the Great Barrier Reef sees pods of dwarf minke whales as they migrate through the waters off Port Douglas. Poseidon is one of only three boats in the area that allows its guest to swim with these phenomenal animals. We operate under guidelines imposed by the Great Barrier Reef Marine Park Authority, whose interest is keeping all the animals and marine life of the park safe. Groups of 10 people can be positioned on a floating life, ensuring not to disrupt the whales, leaving them in control of the encounter. But don't worry - they are curious animals and usually come by to say hi! Although there is no guarantee of seeing any whales, sightings are frequent during the winter months. 

Reef sites
You’ll head to Agincourt Reef during your day trip with Poseidon! The reef sites here offer clear waters teeming with marine life. Endless numbers of cod, parrotfish, angelfish, clownfish, giant clams, reef sharks, corals, anemones and more await for you to discover and enjoy during your one-day diving experience. Divers will get to visit its depths, while snorkellers get the chance to see the corals sitting near the surface in the shallow coral lagoons for an unforgettable day. We have over 25 sites to choose fro, ensuring the best conditions on your day of travel.

"As a super keen diver, I did this trip solo but was immediately paired up with another girl my age who will now be a lifelong friend. This trip is super focused on maximising your time underwater so we were organising our gear on the way out and as soon as the boat reached the first site we were underwater! The diving was the best I have done in Australia and super varied between the 3 sites on the Outer Agincourt Reef. Thank you for a sick day!"
