Wavelength Reef Tours Port Douglas


In keeping with our philosophy of low impact tourism, WAVELENGTH takes only a maximum of 30 people on each tour. This is the lowest group number of any Outer Reef operator in Port Douglas, Australia. Our commitment to sharing the unique Great Barrier Reef environment with small groups, allows you to explore this place of incredible beauty and awesome diversity, in a very unique and personalized way. Our professional and attentive crew ensures that each and every passenger’s needs and expectations are met.

Our philosophy comes straight from the founder of Wavelength and Eco Tourism pioneer- Steve Simpson. This excerpt taken from an interview for the Sydney Morning Herald in Oct 2004 :

“My basic philosophy is that by taking people out to the reef, telling them about the reef and our concerns for the reef; they actually become aware of the issues and go and talk to other people. The more people know about it, the more they are likely to put their hands up and rant and rave about it. If it is locked away and untouched, no one really knows or cares about it”


A visit to the Great Barrier Reef can be a once in a lifetime experience so you want to make every moment count. WAVELENGTH is the only operator in Port Douglas that dedicates every facet of the day to Snorkellers and their unique requirements. Whether you are a novice or an experienced free-diver we provide the Great Barrier Reef sites, the time and expert advice that allow you to truly experience the world’s most diverse eco-system up close and personal. 90% of the Great Barrier Reef diversity occurs in the top 4 meters of water so snorkeling is the most enjoyable and relaxed way of immersing yourself in this environment.


In over 20 years of operation WAVELENGTH have picked the best snorkel sites within the Port Douglas area, and have installed many exclusive use moorings, which cover the full range of reef types, distribution of plant and animal species and a variety of snorkeling conditions. Through our huge choice of Great Barrier Reef sites we endeavour to reveal as many aspects of the Great Barrier Reef as possible in one day. On any given day, WAVELENGTH guests can experience three different areas with contrasting fish, coral and plant populations.


WAVELENGTH is one of Port Douglas’ original Great Barrier Reef tour operators and is still owned and operated by eco-tourism pioneer Steve Simpson. Steve’s keen interest in conservation and his love of the Far North reef system has led to WAVELENGTH becoming leaders in reef conservation.

WAVELENGTH is one of only two Great Barrier Reef tour companies in the area to have been awarded Advanced Ecotourism Accreditation by the ECOTOURISM ASSOCIATION OF AUSTRALIA.
