A Closer Look at the Big Reef

It can be seen from outer space, but to truly appreciate Australia's Great Barrier Reef, you need to get up close, jump in and duck under. Clear waters reveal schools of colorful fish circling towering coral castles known as bommies. Closer looks into crevices reveal a wealth of small marine life treasures, while out in open water, turtles, rays and the occasional shark cruise by. With literally 3,000 reefs stretching over 1,200 miles to choose from, the possibilities seem limitless. Snorkelers can come for the day aboard fast, spacious excursion boats; spend time on a private island, or sign up for a liveaboard cruise to more distant regions of the reef.

Australia Information

Snorkeling in Australia Overview

There are several ways snorkels can access the best snorkel sites along Australia's Great Barrier Reef. Boats depart daily from the port city of Cairns to visiting a range of sites that includes shallow reefs and stand-alone coral outcroppings. On Heron Island, an upscale dive lodge puts snorkelers close to sites along the eastern edge of the reef. Some diving liveaboard will also accommodate snorkelers on cruises to the Ribbon Reefs.

Snorkeling in Australia Tips

If you come across a large fish hovering motionless over a coral head, pause and take a closer look. You may have found a cleaning station. At numerous points on Australia's coral reefs, small shrimp and fish such as gobies and wrasse will perform grooming services by nibbling away at parasites that cling to the skin of fish, turtles and rays.

Best Places for Snorkeling in Australia

The corals at Milln Reef rise right to the surface. The Horseshoe is a maze of outcrops known as bommies that are riddled with swim-throughs and chasms. At the Cod Hole, snorkelers come face to face with huge grouper. Guests staying at Heron Island can snorkel right from the beach, or take a boat to the colorful formations of the Wistari Reefs.

What to Pack for Snorkeling in Australia

For day trips, add a light cover up to wear on the ride there and back. For liveaboard trips, pack in soft-sided luggage that can be easily stowed in a boat cabin. The Cairns-based operators Caradonna represents supply all needed snorkeling equipment, including wetsuits and lycra skinsuits.

Passport and/or Visa Requirements

American citizens are required to have a valid U.S. passport to enter Australia with at least one blank page for the entry stamp. An Australian Visa is required, or if eligible, an electronic visa, through Electronic Travel Authority (ETA) at The ETA replaces a visa and allows a stay of up to 90 days. The ETA may be obtained from their website for $20 AUD. Airlines and many travel agents in the United States are also able to apply for ETAs on behalf of travelers. Please note that American citizens who overstay their ETA or visa, even for short periods, may be subject to exclusion, detention, and removal.


There are no required immunizations for U.S. citizens to enter Australia, but we would always suggest checking with your doctor and the Centers for Disease Control on recommended vaccinations for travel to Australia at Traveler's Health CDC Australia.

Culture and Customs

For visitors from North America, Australia may seem like a favorite cousin who talks a bit funny and never met someone they didn't like. Portrayals of the Land Down Under often include a “no worries” attitude, which is an accurate representation of the hospitality visitors can expect. But laid back can be far from boring. In stark contrast to the cosmopolitan coastal cities to the south, Cairns is not only the gateway to the Great Barrier Reef but also the nation's epicenter for outdoor sports and adventures. Big game fishing charters, speedboat runs, jet ski tours and parasailing adventures take place in warm tropical waters, while on land, skydivers, climbers and bungee jumpers shun their fear of heights. Forays into the rainforest take place on foot, aboard motorcycles and mountain bikes or via offload vehicle. Aboriginal parks provide a glimpse of Australia's cultural heritage; zip line canopy rides spice up rainforest tours and crocodile-spotting cruises along the Daintree River provide bucket-list bragging rights.
