Located in Queensland, this attraction, along with Uluru and the Sydney Opera House, is one of those attractions that is known by virtually everyone, and is synonymous with Australia. Stretching for approximately 2,300 kms, it is home to a vast wealth of rare, endangered, and unique animal and plant species.
It is hard to recommend one particular area of the reef to visit, but most people agree that the Whitsunday Islands are absolutely stunning, and I recommend taking a 2-3 day sailing trip/tour around the area. With snorkelling and scuba diving areas literally everywhere you are bound to experience wonders that will stay with you for the rest of your life!
