Australia’s Great Barrier Reef

Stretching along the East Coast of Australia for more than 2,000km’s, beginning at the tip of the Cape York Peninsula all the way down to Bundaberg in the south, this internationally acclaimed World Heritage Park encompasses approximately 348,000 square kilometres. The world’s largest living organism, a place of natural beauty and visible from outer space.

The coral reefs are the result of thousands of years of growth by tiny coral animals called Polyps. Mostly living together in colonies, the Polyps secrete a calcium carbonate skeleton which makes up the base of the reef. A single cell algae that lives in the tissues of the Polyps, and 6000-8000 years of growth have created the Great Barrier Reef.

Great Barrier Reef

The Reef, recognised by UNESCO as a World Heritage site in 1981, is the largest site in the world. 

Great Barrier Reef Snorkelling & Scuba Diving

Lady Elliot Island and Heron Island are both well-known diving and snorkelling areas on the reef, but, where is the best place to experience the Great Barrier Reef? list the places they believe to be the best-snorkelling sites in Queensland. The best place to see the reef is entirely dependant on how much time is available and how you will get there. Driving along the full length of the Queensland coast on our national highway 1 with plenty of time will enable you to experience the reef from many of the towns along the way.

Further north, Lizard Island is 27km off the coast (and 100km from Cooktown), this 1000-hectare national park has 24 stunning sandy white beaches, crystal clear water and unbelievable coral surrounding the island. Snorkelling is superb and easy by simply wading out from the beach.

Mission Beach, south of Cairns, is a great location, miles of sandy beaches. Popular for many years with travellers and with easy access to the Tully River area for rafting adventures too.

The islands of the Whitsundays are famously featured on glossy brochures – almost unbelievable turquoise waters, coral,  pristine beaches and bushwalking.

Hook Island is a great base with, arguably, some of the best diving and snorkelling in the Whitsundays or stay on the mainland at (or near) Airlie Beach and visit different islands on day trips. 

 Further south, the Town of  1770 and Agnes Waters boast many options for sailing trips to Lady Musgrove Island, well known for great diving and snorkelling in the Southern Barrier Reef.

The town also boasts some great kayaking adventures, Segway tours, indigenous tours and an awesome bit of fun by joining a ‘biker gang’ to see the historical town and ride your own mini ‘Harley’ style chopper!

Food Web

Who eats what out on the reef? The ecosystem along the reef is a delicate balance of multiple levels of fish and organisms that are co-dependent on each other for survival. From the Reef Shark, all the way down to the tiniest microscopic organisms called Phytoplankton. A simple diagram of the food web can be found here.
