Six o'clock closing was introduced during the First World War, partly as an attempt to improve public morality and partly as a war austerity measure. Before this reform, most hotels and public houses in Australia had closed at 11 or 11:30 pm. Support for changing hotel closing times originally came from the temperance movement, which hoped that implementing restrictions on the sale of alcohol would lead eventually to its total prohibition. Although the movement had been active since the 1870s, it had been gaining ground since the 1900s following the introduction of 6 o'clock retail trade closing, first legislated in Western Australia in 1897. The argument made by the temperance movement challenged the grounds for public houses being "kept open while bakers' shops were shut". Prominent groups in this movement were the Woman's Christian Temperance Union and the Rechabites. Their agitation was augmented with the outbreak of war in 1914 where it was argued that a "well-ordered, self-disciplined and morally upright home front was a precondition for the successful prosecution of the war."
