Here's your chance to visit the world's richest marine habitat -- Australia's magnificent Great Barrier Reef.

Board a high-speed catamaran and in just 90 minutes you will arrive at a mooring on the outer Great Barrier Reef. A UNESCO World Heritage Site, the reef is considered to be one of the Seven Natural Wonders of the World. The many reefs and atolls that make up the reef are rich with coral, fish, mollusks, and visiting sharks, dolphins, and turtles.

A presentation by a marine naturalist on board the boat will prepare you for the exquisitely beautiful underwater world that lies ahead.

Don your snorkel equipment and jump into the water for an active Barrier Reef experience with plenty of time to swim and snorkel in the Outer Reef environment.

Witness the majestic panoramas of colorful tropical fish and intricate coral gardens.

Enjoy a tropical buffet lunch, served in air-conditioned comfort aboard the vessel.

The more adventurous may wish to try an introductory or certified scuba experience (at your own expense).

As part of your memorable day, you can choose to participate in the Great Barrier Reef Marine Park Authority's Eye on the Reef monitoring program. This is a chance to 'give back' and help make a difference to the reef as you identify and record the varieties of sea life discovered during your day. This information is used in studies and is a valuable tool in helping the Marine Park continually monitor the reef environment at various locations.

After you've spent a breathtaking few hours out at the mooring, a 90-minute journey will return you to the pier.


Swimming/snorkeling is undertaken in a deep-water environment from the back of a vessel, not from a sandy shore. Access to the water is directly from the back of the vessel and instruction will be given to those who need assistance. Wear your swimsuit under your clothing; bring a towel, sunscreen and a hat. Tour does not operate on holidays. Bring cash or credit cards for drinks and purchases. Swimming/ snorkel activities are undertaken at your own risk. Wear your swimsuit; bring a towel, biodegradable/reef-safe sunscreen and a hat. Guests with heart problems, epilepsy, diabetes or asthma are not allowed to participate in snorkeling.
