New South Wales
New South Wales (often abbreviated to NSW) is a state on the southeast coast of Australia. It is Australia's most populous state. Just under two-thirds of the state's population, 5.3 million, live in the Greater Sydney area. The Colony of New South Wales was founded as a British penal colony in 1788. The colony originally comprised more than half of the Australian mainland, before it was divided up into other colonies during the 19th century.
Geography
Most of the inhabitants of NSW live on the narrow strip of fertile river valleys and plains along the coast. Rising immediately to the west are the tablelands (plateaus), gorges and mountains of the Great Dividing Range. The western slopes of these highlands are—except in the south—quite gentle, forming an area of undulating farmland intersected by rivers. The higher slopes are covered with eucalyptus forest. Semi-arid plains stretch off to the west beyond the Darling River, merging into sandy desert in the north or mallee scrubland in the south. Irrigation is made possible by dams and weirs on the westward-flowing rivers, including the Murray, Lachlan, Murrumbidgee and Darling. Drought, bushfires and floods are ever-present natural threats across the entire state.
The coastal strip of New South Wales enjoys hot summers and mild winters. The climate in the North Coast, bordering Queensland, is humid subtropical, with bouts of heavy rain in summer and occasionally cyclones. Inland areas of the state, which have a semi-arid to arid climate, are both hotter in summer and colder in winter. Temperatures are cooler in the mountains, becoming coldest in the high Snowy Mountains region of the Australian Alps around Mount Kosciuszko, where heavy snow falls in winter.
Economy
Since the 1970s, old industries such as steel and shipbuilding have largely disappeared, to be replaced by information technology companies (especially in the Macquarie Park area) and financial services centred on Sydney. Coal and related products remains the state's biggest export, however, although the state is committed to wind and solar energy and the construction of large-scale batteries to store this energy.
Tourism has also become important to the NSW economy. It is also centred on Sydney but also around the North Coast towns of Coffs Harbour and Byron Bay.
Cattle, sheep and pig farming has been present since domestic animals were imported during the early days of European settlement. The Northern Tablelands are prime sheep and cattle country, while cotton is grown in the Namoi Valley of northwestern New South Wales. On the central slopes there are many fruit orchards, while blueberries and sugar cane are grown in northern subtropical areas. The Hunter Valley and Riverina region near Wagga Wagga are both major wine-producing areas.
Sydney
Sydney, the capital city of New South Wales, is Australia's and Oceania's most populous city. The urban area surrounds Port Jackson, while its suburbs extend inland about 70 kilometres (45 miles) towards the Blue Mountains, part of the Great Dividing Range. Residents of the city are known as "Sydneysiders".
Around 29 clans of Aboriginal Australians (chiefly the Darug, Guringai and Dharawal speaking peoples) inhabited the region now called Sydney at the time Europeans first arrived on the continent. During his first Pacific voyage in 1770, Lieutenant James Cook and his crew became the first Europeans to set foot on Australian soil when they made landfall at Botany Bay. In 1788, the First Fleet of convicts, led by Captain Arthur Phillip, founded Sydney as a British penal colony, the first European settlement in Australia. Phillip named the settlement after Thomas Townshend, Lord Sydney, the British Home Secretary at the time.
Phillip soon founded another settlement upriver at what he originally called Rose Hill (later re-named Parramatta, after the local Aboriginal name), which offered better farmland than the area of poor soils around Sydney Cove. Parramatta is today a major commercial centre in Greater Western Sydney.
Lachlan Macquarie, Governor of New South Wales from 1810 to 1821, began the process of transforming the Sydney from a penal colony to a town for free settlers and a colonial capital, with roads and public buildings.
Penal transportation to New South Wales ended soon after Sydney officially became a city in 1842. Sydney's population expanded rapidly after the gold rushes of the 1850s. Over the next century, Sydney transformed from a colonial outpost into a major global centre. In recent decades, it has become one of the most multicultural cities in the world, with more than 250 different languages spoken and more than 45% of the population reported having been born overseas. The city is established as Australia's financial capital, and is a major centre of tourism.
