Bar closing times were extended to 10 pm in Tasmania in 1937. Queensland followed suit in December 1941, after opposition within the state government subsided. The issue of ending early closing was put to voters in New South Wales in a referendum in 1947, but it was rejected; in the same year, 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.
