<P> Early public house closing times had only limited success; they did not have a significant effect on reducing alcohol consumption and probably contributed to the growth of "sly - grog" venues and the illicit alcohol trade . In many cases, patrons would buy alcohol at bottle shops to consume at home after the six o'clock swill . </P> <P> Six o'clock closing often fuelled an hour - long speed - drinking session, as men raced to get as drunk as possible in the limited time available . An unintended consequence was that glasses were saved during the hour after quitting time until the last call came for drinks . Then, the emptied glasses could be refilled . "The bartender didn't carry your glass to the tap . He carried a pistol - shaped spigot hitched to a long tube and squirted your glass full where you stood ." </P> <P> Bar closing times were extended to 10 pm in Tasmania in 1937 . The issue of ending early closing was put to voters in New South Wales in a referendum in 1947, but it did not achieve the required number of votes to pass . Around the same time, the Supreme Court of New South Wales ruled that private clubs were exempt from alcohol restrictions, allowing them to trade alcohol legally after 6 pm . A second referendum held in 1954 narrowly passed, and closing hours were extended to 10 pm in New South Wales in the following year . Hours were extended in Victoria in 1966, and South Australia was the last state to abolish six o'clock closing with legislation introduced by Don Dunstan in 1967 and the first legal after - six beer being drunk on 28 September . </P> <P> Bar closing times were extended to 10 pm in New Zealand on 9 October 1967, three weeks after a referendum . An earlier referendum, in 1949, had voted three to one to retain six o'clock closing, but there was partial repeal of the law in 1961, which allowed restaurants to sell liquor until midnight but not hotel bars . </P>
