The Great Barrier Reef has an almost magical place in the minds of divers. Its 1,200 miles of coral atolls and islands are home to some of the world’s most renowned diving areas such as the Ribbon Reefs, Osprey Reef and the Coral Sea. The more remote areas can only be reached by live-aboard but there are plenty of sites for land-based divers to explore by day and return to the comfort of their hotels by happy hour. Experience the country’s unique nature and culture by visiting the aboriginal parks, outback camps and the spectacular coastal regions of Daintree National Park and Cape Tribulation. One of the most impressive ways to see the Great Barrier Reef is by helicopter or seaplane. Air tours can include deserted island picnics and a drop-off at the Kuranda’s World Heritage Rainforest with a return to Cairns via the Kuranda Scenic Railway.

Australia Information

Diving in Australia

So extensive it is even visible from outer space, the Great Barrier Reef is the longest reef system in the world and perhaps the most biologically diverse aquatic habitat on Earth. It encompasses 1,250 miles of coral ramparts, islets and cays that flank the east coast of Australia, and is the largest marine park in the world. At some points along the way, the reef reaches more than 200 nautical miles out into the Coral Sea. Even people who have spent a lifetime diving the Great Barrier Reef have not seen it all.

This exotic “Land Down Under” is filled with a wondrous collection of marinelife so bizarre that no other place on earth is quite like it. Along with the usual menu of high-voltage animals such as mantas, whales and sharks, you can also find blue ring octopus, sawfish, ribbon eels, giant clams, harlequin tuskfish, wobbegong sharks and the giant potato cod. Delicate soft corals grow to the size of a Christmas tree and starfish are electric blue. Diving Australian waters generally requires long-range live-aboards, because many of Australia’s best sites are remote and therefore relatively untouched. Day boats can get you to good dive sites, but the best diving is generally beyond the Great Barrier Reef in the Coral Sea.

Renowned for crystalline water, outstanding marine life and absolutely gorgeous reefs, the Coral Sea lies off the northeast coast of Australia, well beyond the Great Barrier Reef. Quite remote, this remarkable body of water is relatively untouched with not one inhabited island within this vast realm that is equivalent in size to the entire Caribbean. Spanning more than 1.5 million square miles of ocean, the Coral Sea contains hundreds of separate reefs, atolls, cays, and seamounts. Distances are so great that only one or two reef systems can be visited on a single dive trip. The Coral Sea is known for vertical walls, enormous sea fans, trees of soft corals like giant crayon-colored broccoli, plenty of sharks, and water so clear that divers appear to be suspended in air.

Cod Hole, one of Australia’s ultimate places to dive, is located in the northern part of the Great Barrier Reef and is named after the giant groupers known as the potato cod. These friendly giants can reach up to 500 pounds and enjoy interacting with divers. Pixie Pinnacle, just south of Cod Hole, has an incredible concentration of marinelife for one small site - it’s all here - mantis shrimp, leafy scorpion fish, clownfish, lionfish, soft corals, giant fans, a proliferation of crinoids, nudibranchs and much more. Off the wall, Cheyron barracudas will parade past, as will dogtooth tunas, jacks and an occasional shark.

While the Great Barrier Reef is accessible via a day trip out of either Cairns or Port Douglas, the best sites are only accessible from the comforts of a live-aboard dive vessel. There are several options for divers looking to explore this world renowned dive destination from the comfort of a live-aboard. While a 7-night itinerary will visit all of the main sites, divers have the option of taking 3 or 4-night itineraries as well which include a low level flight along the Great Barrier Reef. Some itineraries also visit the remote site of Osprey Reef where shark encounters are the big attraction. Check the current weather in Australia here.

Passport and/or Visa Requirements

American citizens are required to have a valid U.S. passport to enter Australia and must enter with an Australian visa or, if eligible, through Electronic Travel Authority (ETA) at The ETA replaces a visa and allows a stay of up to three months.

Culture and Customs

Much of Australia's culture is derived from European roots, but distinctive Australian features have evolved from the environment, aboriginal culture, and the influence of Australia's neighbors.

In Cairns, you can learn more about Australia’s aboriginal culture and experience the spirit world of the Aboriginal Dreamtime at Tjapukai Aboriginal Dance Theatre. For a real Aussie Outback experience, visit Undara where overnight accommodations are in restored railway carriages and explore the savannah and its wildlife, hike through Earth’s longest lava tubes and finish the day around the campfire under the stars.

A trip to Australia isn’t complete without some Aussie adventures: In the Cairns area you can enjoy hot air ballooning at dawn, white water rafting, parasailing and even sky diving. If visiting the rainforest canopy sounds more your style, the Kuranda Skyrail just north of Cairns takes you on a journey above the treetops for nearly five miles. Plan on a full day before returning, because you’ll want to experience all that Kuranda has to offer.

About an hour north of Cairns in northern Queensland, the thick, dry scrub brush of the outback gives way to the only back-to-back World Heritage Sites on our planet - the vast Daintree and Cape Tribulation rainforests. The area offers one of the most scenic drives in the world and starts when you cross the Daintree River on the car ferry. See the area by scenic river cruise, kayaking, hiking, 4WD vehicle, or even horseback. Miles of deserted beaches are yours to explore where the rainforest meets the sea. Local wildlife in the area includes a wide variety of exotic birds including the endemic Mountain Thornbill and the giant Southern Cassowary as well as the elusive salt water crocodile.

Electricity, Telephone and Internet Access

Standard electricity in Australia is 240 volts, alternating at 50 cycles per second. When coming from the United States you will need an adapted socket and also a voltage converter if your appliances are not equipped to handle 240 volts.

The international access code for Australia is 61. Pre paid phone cards are available in stores to make local, long distance and international calls.

Internet cafes are abundant throughout the Cairns area and hotels also offer WIFI usually free of charge.

Water Quality

The water is safe to drink.

History, Art, and Culture

Australia was uninhabited until stone-culture peoples arrived, perhaps by boat across the waters separating the island from the Indonesia archipelago more than 40,000 years ago. Portuguese, Spanish, Dutch, and English explorers observed the island before 1770, when Captain Cook explored the east coast and claimed it for Great Britain.

On January 26, 1788 (now celebrated as Australia Day), the First Fleet under Captain Arthur Phillip landed at Sydney, and formal proclamation of the establishment of the Colony of New South Wales followed on February 7. Many, but by no means all, of the first settlers were convicts, some condemned for offenses that today would often be thought trivial. The discovery of gold in 1851 led to increased population, wealth, and trade.

The six colonies that now constitute the states of the Australian Commonwealth were established in the following order: New South Wales, 1788; Tasmania, 1825; Western Australia, 1829; South Australia, 1836; Victoria, 1851; and Queensland, 1859. Discussions between Australian and British representatives led to adoption by the British Government of an act to constitute the Commonwealth of Australia in 1900. In 1911, control of the Northern Territory was transferred from South Australia to the Commonwealth. Also that year, the Australian Capital Territory (where the national capital, Canberra, is located), was established. The Northern Territory and Australian Capital Territory were granted self-government in 1978 and 1988, respectively.

Australia passed the Statute of Westminster Adoption Act on October 9, 1942, which officially established Australia's complete autonomy in both internal and external affairs and formalized a situation that had existed for years. The Australia Act (1986) eliminated almost all remaining vestiges of British legal authority, including the ability to appeal to the British Privy Council.
