Port Jackson in the context of "Middle Harbour"

The history of Australia from 1788 to 1850 covers the early British colonial period of Australia's history. This started with the arrival in 1788 of the First Fleet of British ships at Port Jackson on the lands of the Eora, and the establishment of the penal colony of New South Wales as part of the British Empire. It further covers the European scientific exploration of the continent and the establishment of the other Australian colonies that make up the modern states of Australia.

After several years of privation, the penal colony gradually expanded and developed an economy based on farming, fishing, whaling, trade with incoming ships, and construction using convict labour. By 1820, however, British settlement was largely confined to a 100-kilometre (62 mi) radius around Sydney and to the central plain of Van Diemen's land. From 1816, penal transportation to Australia increased rapidly and the number of free settlers grew steadily. Van Diemen's Land became a separate colony in 1825, and free settlements were established at the Swan River Colony in Western Australia (1829), the Province of South Australia (1836), and in the Port Philip District (1836). The grazing of cattle and sheep expanded inland, leading to increasing conflict with Aboriginal people on their traditional lands.

A ria (/ˈriːə/; Galician: ría, feminine noun derived from río, 'river') is a coastal inlet formed by the partial submergence of an unglaciated river valley. It is a drowned river valley that remains open to the sea.

Cork Harbour (Irish: Cuan Chorcaí) is a natural harbour and river estuary at the mouth of the River Lee in County Cork, Ireland. It is one of several which lay claim to the title of "second largest natural harbour in the world by navigational area" (after Port Jackson, Sydney). Other contenders include Halifax Harbour in Canada, Trincomalee Harbour in Sri Lanka and Poole Harbour in England.

The harbour has been a working port and a strategic defensive hub for centuries, and it has been one of Ireland's major employment hubs since the early 1900s. Traditional heavy industries have waned since the late 20th century, with the likes of the closure of Irish Steel in Haulbowline and shipbuilding at Verolme. It still has strategic significance in energy generation, shipping, refining and pharmaceuticals development.

Sydney Cove (Eora: Warrane) is a bay on the southern shore of Sydney Harbour, one of several harbours in Port Jackson, on the coast of Sydney, New South Wales. Sydney Cove is a focal point for community celebrations, due to its central Sydney location between the Sydney Opera House and the Sydney Harbour Bridge.

Sydney Cove was the site of the First Fleet's landing on 26 January 1788 and the subsequent raising of the Union Jack, a seminal date in Australian history now marked as Australia Day.

Bennelong Point is a headland and former island on the shores of Sydney Harbour that is the location of the Sydney Opera House. It forms the eastern flank of Sydney Cove, and has played an important role in the history of Sydney since European settlement in the late 18th century.

The Rocks is a suburb, tourist precinct, and historic area of Sydney's city centre. It is on the southern shore of Sydney Harbour, and immediately north-west of the Sydney CBD.

Sydney New Year's Eve is an annual New Year's Eve fireworks event in Sydney, New South Wales, Australia. The event currently consists of two fireworks shows, with an evening display known as the Calling Country Fireworks (formerly, the Family Fireworks) held at 9:00 p.m. AEDT, and the main Midnight Fireworks, held at 12:00 a.m. Fireworks are launched from barges in Port Jackson, as well as nearby landmarks such as the Sydney Opera House, and the Sydney Harbour Bridge, which serves as the main focal point of the show via lighting and pyrotechnic effects.

As one of the first major cities to celebrate the New Year, the event is widely-viewed in Australia and worldwide. Organizers have estimated the annual in-person attendance of the event to be around 1.5 to 1.6 million, with tourists accounting for a large portion of its attendees. Some locations, such as the Royal Botanic Garden, host ticketed seating areas.

Whaling in Australian waters began in 1791 when five of the 11 ships in the Third Fleet landed their passengers and freight at Sydney Cove and then left Port Jackson to engage in whaling and seal hunting off the coast of Australia and New Zealand. The two main species hunted by such vessels in the early years were right and sperm whales. Humpback, bowhead and other whale species would later be taken.

Whaling went on to be a major maritime industry in Australia providing work for hundreds of ships and thousands of men and contributing export products worth £4.2 million by 1850.
