Prohibition of the sale and consumption of alcohol became law in the United States of America early in 1920. In Adelaide the issue was discussed and the subject of a referendum raised. Bishop Thomas, the Anglican Bishop of Adelaide, not only devoted a sermon to the topic - in support of prohibition - but also had the sermon printed and distributed. In fact, sale of alcohol was already restricted in South Australia by the 'Early Closing' Act, which from 1915 to 1967 required hotels to close at 6 pm and prohibition was never seriously considered anywhere in Australia.
