Tryon Island (Tryon Island)
Tryon Island is a coral cay located in the southern Great Barrier Reef, 86 km northeast of Gladstone, Queensland, Australia, and 465 km north of the state capital Brisbane. The island is a protected area and forms part of Capricornia Cays National Park. It is part of the Capricornia Cays Important Bird Area. The cay covers an area of 0.21 km2 and is surrounded by a coral reef that is partially exposed at low-tide.
On Tryon Island, there is beach rock along the north western and south eastern beaches. The cay has in the past been covered with dense vegetation.
The Capricorn and Bunker Cays form part of a distinct geomorphic province at the southern end of the Great Barrier Reef. The cays and their reefs lie on the western marginal shelf, and are separated from the mainland by the Curtis Channel. The cays are not generally visible from the mainland, although Masthead Island may be viewed from Mount Larcom on a clear day.
Geologically, the cays are young, having developed during the Holocene period, they are mostly around 5000 years old. The sea level was much lower during the last ice age (at the end of the Pleistocene period) and the coastal plain on which today's reefs and cays developed was completely exposed. Early in the Holocene (around 10,000 years ago), the sea level began to rise until it stabilised at its present level around 6000 years ago. Once the sea level stabilised, it was possible for reef flats to expand and provide potential sites for the formation of cays.
Tryon Island is a vegetated sand cay placed atop of a platform reef.

The ancestors of Aboriginal Australians began arriving from south east Asia approximately 65,000 years ago, during the last ice age. Arriving by sea, they settled the continent and had formed approximately 250 distinct language groups by the time of European settlement, maintaining some of the longest known continuing artistic and religious traditions in the world. Australia's written history commenced with the European maritime exploration of Australia. The Dutch navigator Willem Janszoon was the first known European to reach Australia, in 1606. In 1770, the British explorer James Cook mapped and claimed the east coast of Australia for Great Britain, and the First Fleet of British ships arrived at Sydney in 1788 to establish the penal colony of New South Wales. The European population grew in subsequent decades, and by the end of the 1850s gold rush, most of the continent had been explored by European settlers and an additional five self-governing British colonies established. Democratic parliaments were gradually established through the 19th century, culminating with a vote for the federation of the six colonies and foundation of the Commonwealth of Australia on 1 January 1901. Australia has since maintained a stable liberal democratic political system and wealthy market economy.
