When six o’clock closing was introduced for pubs in Victoria, New South Wales and Tasmania  it led to grumblings about the ‘six o’clock rush’. The term ‘six o’clock swill ‘ did not emerge until the 1940s, after WWII. Thanks to the ‘wowsers’, an Australian term which came to mean one who condemned the pleasure of others,  six o’clock closing prevailed in some states until the 1960s, despite many Australians’ deep distrust of those who didn’t drink.
