colony. A new body was created to advise the governor on the administration of South Australia in 1843 called the Legislative Council. It consisted of three representatives of the British Government and four colonists appointed by the governor. The governor retained total executive power. In 1851, the Imperial Parliament enacted the Australian Colonies Government Act, which allowed for the election of representatives to each of the colonial legislatures and the drafting of a constitution to properly create representative and responsible government in South Australia. Later that year, propertied male colonists were allowed to vote for 16 members on a new 24 seat Legislative Council. Eight members continued to be appointed by the governor. The main responsibility of this body was to draft a constitution for South Australia. The body drafted the most democratic constitution ever seen in the British Empire and provided for universal manhood suffrage. It created the bicameral Parliament of South Australia. For the first time in the colony, the executive was elected by the people, and the colony used the Westminster system, where the government is the party or coalition that exerts a majority in the House of Assembly. The Legislative Council remained a predominantly conservative chamber elected by property owners. Women's suffrage in Australia took a leap forward – enacted in 1895 and taking effect from the 1896 colonial election, South Australia was the first government in Australia and only the second in the world after New Zealand to allow women to vote, and the first in the world to allow women to stand for election. In 1897 Catherine Helen Spence was the first woman in Australia to be a candidate for political office when she was nominated to be one of South Australia's delegates to the conventions that drafted the constitution. South Australia became an original state of the Commonwealth of Australia on 1 January 1901. Although the lower house had universal suffrage, the upper house, the Legislative Council, remained the exclusive domain of property owners until the Labor government of Don Dunstan managed to achieve reform of the chamber in 1973. Property qualifications were removed and the Council became a body elected via proportional representation by a single state-wide electorate. Since the following 1975 South Australian state election, no one party has had control of the state's upper house with the balance of power controlled by a variety of minor parties and independents.
