We had a really lovely time visiting fitzroy Island yesterday. On our way back to cairns we sat on the upper sun deck with great views this only got bettter when we had an unexpected visitor join us 🐳🐋 The crew promptly turned the engines off and gave us an informative commentary on the humpback whales migration. This was such an unexpected treat not to mention a life long bucket list goal. All staff were friendly and professional. The boat was immaculately clean we will definitely be booking future adventures with this company and recommending to family and friends. Until next time.

Cruise in and out was amazing, we saw Sea turtles mating on the cruise back. Glass bottom boat was incredible, a great view of the coral reef and creatures below. The snorkelling was amazing, I spotted a sea turtle in the area close to the jetty...I was able to capture an underwater picture of the sea turtle. Box lunch was fantastic, very big lunch which satisfied the hard earned appetite. Sunlover staff were very friendly and did an amazing job all day 👏 Entire day was well worth it, would do it again. Highly recommend.

Really great day with our 11 and 13 yo. Food on board the big cat was nice. Activities- we did snorkeling and the kids loved it. We saw so many fish and turtles the kids were in the water all day except to come out for lunch. Ice cream on board and bar was lovely finishing touch. Highly recommended.

Spectacular reef systems

Dive or snorkel over drop-offs, bommies, and coral gardens teeming with fish. Visibility often exceeds 20 meters, especially between June and October.

Guided snorkel & dive options

Expert guides lead small groups through the best coral sections, pointing out camouflaged creatures and rare corals. Ideal for first-timers or anyone looking for a safer, richer reef experience.

Frequent marine encounters

You’ll likely spot turtles, reef sharks, parrotfish, giant clams, and maybe even a manta ray or two. These outer sections draw **a wider mix of reef species.

All-day comfort and service

Full-day tours typically include morning tea, a hearty buffet lunch, afternoon snacks, and optional add-ons like underwater photography or scuba upgrades.

Best places to snorkel in the Outer Great Barrier Reef

1/3

Norman Reef

Norman Reef, with crystal-clear water and excellent visibility, hosts vibrant marine life, colorful corals, and occasional green sea turtles. Its varying depths suit both beginners and confident swimmers.

Saxon Reef

Saxon Reef, between Norman and Hastings, is quieter but rewarding, with bommies, coral walls, and abundant fish. You may see anemonefish, giant clams, or a reef shark. Calm waters and healthy coral make it a great all-rounder.

North Hastings Reef

North Hastings has shallow lagoons and deeper drop-offs, ideal for snorkel tours. Spot parrotfish, sea cucumbers, and seasonal manta rays.

Plan your visit to Outer Great Barrier Reef

Snorkeler swimming with a large fish at the Great Barrier Reef near Cairns.

Peak season (June – October): Clear skies, calm seas, and excellent visibility make this the ideal time for snorkeling. It’s also stinger-free, so no suits required.
Shoulder season (April – May, November): Fewer crowds and still-great weather. You’ll get good underwater conditions and better tour availability.
Wet season (December – March): Expect high humidity, tropical showers, and reduced visibility. Snorkeling is still possible, but trips are more weather-dependent.
