diminished, the average income of miners fell. Victorian miners increasingly saw the flat monthly licence fee as a regressive tax and complained of official corruption, heavy-handed administration and the lack of voting rights for itinerant miners. Protests intensified in October 1854 when three miners were arrested following a riot at Ballarat. Protesters formed the Ballarat Reform League to support the arrested men and demanded manhood suffrage, reform of the mining licence and administration, and land reform to promote small farms. Further protests followed and protesters built a stockade on the Eureka Field at Ballarat. On 3 December troops overran the stockade, killing about 20 protesters. Five troops were killed and 12 seriously wounded. Following a Royal Commission, the monthly licence was replaced with an annual miner's right at a lower cost which also gave holders the right to vote and build a dwelling on the gold fields. The administration of the Victorian goldfields was also reformed. Stuart Macintyre states, "The Eureka rebellion was a formative event in the national mythology, the Southern Cross [on the Eureka flag] a symbol of freedom and independence.” However, according to A. G. L. Shaw, the Eureka affair "is often painted as a great fight for Australian liberty and the rights of the working man, but it was not that. Its leaders were themselves small capitalists...and even after universal suffrage was introduced...only about a fifth of the miners bothered to vote." Self-government and democracy Elections for the semi-representative Legislative Councils, held in New South Wales, Victoria, South Australia and Van Diemen's Land in 1851, produced a greater number of liberal members. That year, the New South Wales Legislative Council petitioned the British Government requesting self-government for the colony. The Anti-Transportation League also saw the convict system as a barrier to the achievement of self-government. In 1852, the British Government announced that convict transportation to Van Diemen's Land would cease and invited the eastern colonies to draft constitutions enabling responsible self-government. The Secretary of State cited the social and economic transformation of the colonies following the discoveries of gold as one of the factors making self-government feasible. The constitutions for New South Wales, Victoria and Van Diemen's Land (renamed Tasmania in 1856) gained Royal Assent in 1855, that for South Australia in 1856. The constitutions varied, but each created a lower house elected on a broad male franchise and an upper house which was either appointed
