Kangaroo Island, another island in Australia, which has an eco-tourism treasure. It is Australia's third largest island, located off the coast of South Australia's Fleurieu Peninsula, and its stunning beauty and diverse species attract visitors from all over the world. It's also a popular gastronomy destination.

Kangaroo Island has a Mediterranean climate, with warm to hot dry summers (December-February) and low humidity, as well as moderate, mild winters (June-August), making it a year-round destination. In fact, the cooler months of May through September are the best time to witness wildlife in the field for people wanting wildlife experiences! This is a hotspot for animals. Despite a thriving agricultural business, about half of the original vegetation has been preserved, and 30 national and conservation parks protect over a third of the area. This provides an ideal home for a diverse diversity of fauna, with some species becoming exclusive to the Island.

As a result, it is one of the world's best natural-based vacation spots. Consider a tropical island with native vegetation, wildlife, adventure, and exploration. Where you may enjoy pristine beaches, local wines, and breathtaking sunsets.

Can not forget this beautiful island in Australia, Fraser Island (also known as K'gari and Gari) is a World Heritage-listed island off the coast of Queensland, Australia. It is located in the Wide Bay–Burnett area. The island, its surrounding waterways, and parts of the adjoining mainland are all included as world heritage sites.

In 1992, it was designated as a UNESCO World Heritage Site. With a surface area of 1,840 square kilometers, the island is considered the world's largest sand island. It is also the largest island in Queensland, Australia's sixth largest island, and Australia's largest island on the east coast.

Fraser Island, as the world's largest sand island, could hardly be described as anything less than exquisite. It's no wonder that this UNESCO World Heritage site, which is located on Queensland's coast, has earned a consistent reputation among tourists and holidaymakers over the last decade or so. Fraser Island is considered one of Australia's most beautiful islands. The island, which stretches for 123 kilometers, provides tourists with an up-close and personal interaction with the Great Barrier Reef and its wonders, as well as a variety of on-island activities such as four-wheeling down its 'beach highway' and fishing.

The significance of K'gari is so great that it has been designated as a UNESCO World Heritage Site. K'gari, one of Queensland's five World Heritage sites and part of the Great Sandy National Park, is one of the world's most unique and beautiful island. The island's beauty and biodiversity, which include the only known spot on Earth where rainforest grows on sand dunes, almost half of the world's perched freshwater dune lakes, and huge dunes taller than the Sydney Opera House, have earned it this classification.

Moreton Island (Mulgumpin) is an island off the coast of South East Queensland, Australia, on the eastern side of Moreton Bay. It is the world's third largest sand island. Moreton Island, along with Fraser Island, makes up the world's largest sand structure. Before colonization, it was the traditional homeland of the Ngugi.

Moreton Island is the world's third largest sand island, but it's much more than sand on this adventurer's slice of paradise, which is nestled in Brisbane's backyard. You can be snorkeling among a swarm of rainbow-colored fish, zooming down a sand dune, basking in a blue lagoon, or hand-feeding wild dolphins in just 75 minutes by ferry from Brisbane. The Moreton National Park, which spans 95 percent of the island, sits in the center, while the island's coastline features pristine beaches with both quiet and surfable waves.

Moreton Island, which is located south of Fraser Island, has a similar form to Fraser Island. Unlike Fraser, the beaches here are great for swimming, sandboarding, and viewing dolphins. From Base Brisbane, day boat cruises can be arranged. If you need to get away from Brisbane after a long week at work, Moreton Island is the ideal getaway.

Here you may even feed wild dolphins by hand. Snorkel among the Tangalooma Wrecks' sunken ships, a man-made dive site now home to fish, dolphins, and dugongs. Take a Desert Safari excursion to toboggan down the golden dunes; you can't stay on the sand island without a little sand adventure. There are numerous walking and hiking trails to choose from, ranging from the easy Blue Lagoon to the more strenuous but rewarding Mount Tempest Lookout hike.

Phillip Island is a small island off the coast of Victoria, Australia, about 125 kilometers (78 miles) south of Melbourne. Governor Arthur Phillip, the first Governor of New South Wales, was named after the island by explorer and seaman George Bass, who arrived in an open whale boat from Sydney on January 5, 1798.

Phillip Island is a natural wonderland off Australia's southern coast, roughly a two-hour drive from Melbourne. Begin your animal adventure at the Koala Conservation Center, where you'll take a walk through the bush in search of koalas in their natural environment. Then, with Wildlife Coast Cruises, go to Seal Rocks to observe one of Australia's largest populations of fur seals. Phillip Island is not just a beautiful island in Australia, but it's also recognized for its spectacular coastal beauty and dense vegetation, but the primary attraction for visitors is the adorable little penguins. The fairy penguins are the world's tiniest penguins, and travelers flock to Phillip Island to observe groups of the tiny penguins swimming from the sea and waddling back to their nesting boxes.

Most journeys to Phillip Island from Melbourne include stops at other interesting sights along the way, as well as photo opportunities. When you view the penguins, please pay attention to the signs that say no flash photography because you could damage them.

The Houtman Abrolhos, often known as the Abrolhos Islands, are a 122-island chain off Australia's west coast. From the northernmost to the southernmost tip of the Indian Ocean, it stretches for 100 kilometers. The beautiful Abrolhos Islands, 60 kilometers off the coast of Western Australia, can be visited in a variety of ways. From Geraldton or Kalbarri, take a charter boat, fishing excursion, or ecotour across the sea, or take to the sky on a scenic flight from Dongara, Kalbarri, or Geraldton.

The islands are key nesting grounds for seabirds such as noddies, shearwaters, and terns in Australia. On the islands, almost two million birds of 35 different species breed. The Abrolhos Islands are also home to Australia's northernmost sea lions. They were once common, but are now considered a "threatened species." The Tammar wallaby and bush rat, as well as dolphins and migratory whales, are among the mammals that call these islands home.

The Abrolhos are home to a diverse range of sea life, including baldchin groper, coral trout, and dhufish, as well as sharks, coral, seagrasses, and more.

Lord Howe Island, part of the Australian state of New South Wales, is an irregularly crescent-shaped volcanic relic in the Tasman Sea between Australia and New Zealand. It is approximately 10 kilometers long and between 0.3 to 2.0 kilometers wide, having a total area of 14.55 km2.

For its uncommon array of flora, birds, and marine life, as well as its spectacular beauty and landscape, the Lord Howe Island group has been included on the UNESCO World Heritage list. On the island, there are about 2240 native vascular plant species, including over 100 endemics. Sixteen are classified as rare, endangered, or vulnerable. The vegetation exhibits sub-tropical and temperate rainforest connections.

This idyllic location is 600 kilometers southeast of Sydney. Tall mountain peaks, coral pools, walking routes, and a variety of fauna can all be found on this volcanic relic. This island is one of the most beautiful islands in Australia. It is also called Australia's 'prestigious' island, and the only way to get there is by plane, so it's likely to be a little out of reach for most backpackers. You'll need to fly from either Sydney or Brisbane.

In the distant depths of Queensland's Great Barrier Reef, there is an island with more than a little magic up its sleeve. Haggerstone Island, 600 kilometers north of Cairns on the Cape York Peninsula, is both secluded and wild.

Haggerstone offers it all: kilometers of white sand beaches where your footsteps will be the only ones left in the sand. A warm climate makes exploring the island's rough nooks and crannies a breeze. A strong sense of isolation that welcomes island life's simplicity. This is the place to go if you want to get away from it all.

Haggerstone Island is a truly unique location that is privately owned and only caters to a small number of visitors that come to appreciate its natural beauty. The majority of the time, you'll be one of ten or fewer guests on the island. Do you want to have the entire island to yourself? This is one of the few Queensland islands available for rent, and it can accommodate up to 12 people. From your daily experiences to what's on your plate, the crew will tailor your stay to your exact specifications. The two coral lagoons are ideal for watersports such as jet skiing, wakeboarding, waterskiing, kayaking, and canoeing. Climb to the top of the hill for panoramic views of the island and adjacent reef systems, or explore the walking trails for a relaxed afternoon. Alternatively, relax on the jetty with a cocktail in hand while watching the local fish and turtles swim beneath you.

Few travelers get the opportunity to enjoy the Outer Great Barrier Reef's raw splendor – or to do so in such a down-to-earth, quiet fashion as you can on lonely Haggerstone, which is out of the path of day trippers. Daily snorkeling visits to the crew's favorite outer reef sites will provide you with even more pristine splendor. You can also explore a shipwreck from the 1840s and World War II treasures buried beneath the surface in coral gardens in these seas.
