Within this paper the development of the Australian Constitution is carefully studied and analysed. The first fleet arrived at the fifth continent at Sydney Cove, today known as New South Wales, in 1788, which marked the beginning of Australias transformation from an English colony of convicts to an independent industrial nation, influenced by the western world. The establishment of the Australia Acts in 1986 enabled the nation to withdraw from the last remaining bit of dependence owed to Great Britain. At this stage it had been a 198-year long process until Australia finally reached full sovereignty. Australia has experienced constant waves of migration from various parts of the world, which has lead to the country becoming culturally diversely populated. Despite such multiculturalism, todays Australian society still profoundly identifies with its former mother country England. Even the first attempts to federate the colonies to Australia during the 19th century, never saw the intention to abandon their “Mother England” or damage their relations. Once the Commonwealth was finally established in 1901 after lengthy negotiations and despite carrying its own Constitution, Australia was still classified as a British colony. Only at this point began the journey to an independent nation. The first stage was successfully reached with the introduction of the Statute of Westminster in 1931, respectively 1942, before the road to independence ended in 1986. The aim of this paper is to demonstrate from a law historic perspective how the state of Australia transformed since the British settlement of the continent.In order to determine how the Federal Supreme court has influenced the historical development of the Australian Constitution, it is necessary to analyse its most significant decisions concerning constitutional law, while also considering its duty as protector of the Constitution.
