Top 5 Hidden Gem Islands in Australia 

Australia can be identified with such world-known places as Sydney, the Great Barrier Reef, or the Gold Coast. However, just outside these well-known destinations there is a group of undiscovered islands that are not on the usual tourist radar. These secret spots promise a more unusual experience instead: pristine nature, exotic wildlife and an opportunity to properly relax and forget about the noise of the daily life.

These off-beat islands are a must-visit by any traveller who wants to include a special touch to his or her trip, and these islands will surely be the cherries on top of any well-organised Australia holiday packages. Whether it is wilderness hideaways or nature reserves and heritage scenery, the islands offer astonishing diversity and memorable allure. So without further ado, here are five of the most underrated island escapes in Australia.    

Here are the Top 5 Hidden Gem Islands in Australia  

 

1. Lord Howe Island, New South Wales

Lord Howe Island is an exclusive haven that is just two hours away by airplane ride north of Sydney. Part of the reason why this UNESCO-listed island is so exclusive is that it can only accommodate 400 visitors at once, making it an intimate destination with turquoise lagoons and volcanic mountains. The island is a center of hiking, snorkeling and bird watching. Many places have no mobile signal, so it is an ideal location to switch off and enjoy the natural beauty.

2. Flinders Island, Tasmania

Located in the Bass Strait of Tasmania, Flinders Island is wild and ruggedly beautiful and perfectly suited to the nature lover. The island has granite mountain ranges, long beaches of white sand and a lot of wildlife such as wombats and wallabies. You will be able to take part in activities like trekking, fishing and even diving in clear blue waters. Its small local population means that you will have peace, solitude and all the space you need to explore at your own pace.

3. Haggerstone Island, Queensland

Haggerstone Island is a small tropical paradise that is privately owned and is situated at the northern end of the Great Barrier Reef. It is an exclusive retreat having rustic appeal with all the luxury comforts. The island offers only a few lodges, resulting in a more personal experience due to its remote location. They can either snorkel along the coral gardens, be pampered with gourmet meals prepared using fresh catches or even ride in scenic helicopter tours above pristine marine life ecosystems.

4. Maria Island, Tasmania

Maria Island is situated only off the east coast of Tasmania and is a famous destination due to its historical ruins and flourishing wildlife. The island has no cars and can only be reached by ferry, which makes its environment peaceful and pristine. Stroll or ride through beautiful routes, amongst steep rocky cliffs and old convict-style structures. See wombats, kangaroos and even Tasmanian devils on this unusual combination of history and nature at your own pace.

5. Rottnest Island, Western Australia

Rottnest Island, a local favourite but largely unknown to international visitors, is only a short ferry ride from Perth. The island is most popular because of its happy inhabitant the quokka, as well as its turquoise bays and coral reefs. Free of cars, the visitors are welcome to bike across the island, discover secret beaches and indulge in water sports in calm and clear waters. It makes an ideal day outing or weekend.

Conclusion

The secret islands of Australia are a gem waiting to be discovered by people who are not afraid to dig below the mainstream tourist attractions. They provide experiences that are serene and fulfilling- whether it is the view of untouched nature and rare animals or luxury in solitude. These islands are the evidence that the beauty of Australia is not limited to the well-known coastlines and cities, and the adventurous traveller will be rewarded with the views and tales that most people will never have a chance to see.

Adding these undiscovered islands to your Australia tour packages will guarantee you a well-balanced travel experience that is both wondrous, serene and adventurous. Looking to get away to a quiet place, an eco-friendly destination or a picturesque journey, these off-the-beaten-path island treasures have something really special in store- just waiting to be discovered by you.
