Melbourne is rated highly in the areas of education, entertainment, healthcare, research and development, tourism and sports.It is located on the large natural bay of Port Phillip, with its City Centre situated at the northernmost point of the bay – near to the estuary of the Yarra River. The metropolitan area extends south from the City Centre, along the eastern and western shorelines of Port Phillip, and expands into the hinterlands – toward the Dandenong and Macedon mountain ranges, Mornington Peninsula and Yarra Valley. The City Centre is located in the municipality known as the City of Melbourne, and the metropolis consists of a further 30 municipalities. Melbourne has a population of 4,442,918.

It was named "Melbourne" by the Governor of New South Wales, Sir Richard Bourke, in honour of the British Prime Minister of the day, William Lamb, 2nd Viscount Melbourne. It was declared a city by Queen Victoria in 1847, before becoming the capital city of the newly created Colony of Victoria in 1851. During the Victorian gold rush of the 1850s, it was transformed into one of the world's largest and wealthiest cities. After the federation of Australia in 1901, Melbourne served as the interim seat of government for the newly created nation of Australia until 1927.An international centre for performing and visual arts, Melbourne is often referred to as Australia's cultural capital.

In more recent years, it has been recognised as a UNESCO City of Literature and a major centre for street art. It is home to many of Australia's largest and oldest cultural institutions such as the Australian Centre for the Moving Image, the Melbourne Cricket Ground, Melbourne Museum, Melbourne Zoo, the National Gallery of Victoria and the UNESCO World Heritage-listed Royal Exhibition Building.The main passenger airport serving the metropolis and the state is Melbourne Airport, which is the second busiest in Australia, and the Port of Melbourne is Australia's busiest seaport for containerised and general cargo.
