Althorpe Islands (Althorpe Island)
The Althorpe Islands are a group of islands in the Investigator Strait, off the south-western tip of Yorke Peninsula, South Australia. The group includes Althorpe Island and two rocky islets immediately to its west known as The Boobs. These are located 7.7 km south-southwest of Cape Spencer on the mainland. Closer inshore are Seal Island and Haystack Island, which together with Althorpe Island and The Boobs constitute the Althorpe Islands Conservation Park. A management plan for the Althorpe Islands Conservation Park was adopted in 2009. The islands are uninhabited and can only be accessed by sea or by helicopter.

The islands was first sighted by Europeans on Saturday 20 March 1802 from HMS Investigator (1798) whilst under the command of Matthew Flinders. They are reportedly named after the family home of George Spencer, 2nd Earl Spencer, also known as Viscount Althorp, in Northamptonshire which is actually spelled as ‘Althorp'.

Sealers on the cutter Jane and Emma (Captain John Shaw) landed there in October 1851 and took a number of fur seals, Cape Barren Geese and mutton birds. The lighthouse keepers’ cottages which stand today are of State Heritage significance and remain as evidence of the islands’ past contribution to maritime trade and safety. Construction of the Althorpe Island Lighthouse began in 1877. An accident claimed the life of the foreman of works in 1878, slowing the project's progress. Once complete, the lighthouse was operated and maintained by resident keepers from its first light in 1879 until it was demanned in 1991. C. A. Unbehaun supervised the laying of a submarine telephone cable in 1886 from the Althorpes to Cape Spencer.

The light is now automated and is maintained by the Australian Maritime Safety Authority.

Flag of Australia
Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. With an area of 7617930 km2, Australia is the largest country by area in Oceania and the world's sixth-largest country. Australia is the oldest, flattest, and driest inhabited continent, with the least fertile soils. It is a megadiverse country, and its size gives it a wide variety of landscapes and climates, with deserts in the centre, tropical rainforests in the north-east, and mountain ranges in the south-east.

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.
