Samuel Marsden was an English-born priest of the Church of England in Australia and a prominent member of the Church Missionary Society. He played a leading role in bringing Christianity to New Zealand. Marsden was a prominent figure in early New South Wales and Australian history, partly through his ecclesiastical offices as the colony's senior Church of England cleric and as a pioneer of the Australian wool industry, but also for his employment of convicts for farming and his actions as a magistrate at Parramatta, both of which attracted contemporary criticism.

The history of Australia is the history of the land and peoples of the continental land mass and offshore territories which now comprise the Commonwealth of Australia. The Commonwealth of Australia came into existence on 1 January 1901 as a federation of former British colonies, however the human history of Australia commences with the arrival of the first ancestors of Aboriginal Australians by sea from Maritime Southeast Asia between 50,000 and 65,000 years ago, and continues to the present day multicultural democracy.
