The first year in which all the Australian states observed some form of public holiday together on Anzac Day was 1927. By the mid-1930s, all the rituals now associated with the day—dawn vigils, marches, memorial services, reunions, two-up games—became part of Australian Anzac Day culture. New Zealand commemorations also adopted many of these rituals, with the dawn service being introduced from Australia in 1939. With the coming of the Second World War, Anzac Day became a day on which to commemorate the lives of Australians and New Zealanders lost in that war as well and in subsequent wars. The meaning of the day has been further broadened to include those killed in all the military operations in which the countries have been involved. Anzac Day was first commemorated at the Australian War Memorial in 1942, but, due to government orders preventing large public gatherings in case of Japanese air attack, it was a small affair and was neither a march nor a memorial service. Anzac Day has been annually commemorated at the Australian War Memorial ever since. In New Zealand, Anzac Day saw a surge in popularity immediately after World War II. By the 1950s many New Zealanders had become antagonistic or indifferent towards the day. Much of this was linked to the legal ban on commerce on Anzac Day, and the banning by many local authorities of sports events and other entertainment on the day. Annoyance was particularly pronounced in 1953 and 1959, when Anzac Day fell on a Saturday. There was widespread public debate on the issue, with some people calling for the public holiday to be moved to the nearest Sunday or abolished altogether. In 1966 a new Anzac Day Act was passed, allowing sport and entertainment in the afternoon. During and after Australia's involvement in the Vietnam War (1962–1975), interest in Anzac Day reached its lowest point in Australia. On 26 April 1975 "The Australian" newspaper covered the passing of Anzac Day in a single story. In the 1960s and 1970s, anti-war protesters used Anzac Day events as a platform to voice opposition to conscription and Australia's military involvement in general; in the following 20 years, the relevance of Australia's war connection with the British Empire was brought into question. In 1967, two members of the left-wing Progressive Youth Movement in Christchurch staged a minor protest at the Anzac Day ceremony, laying a wreath protesting against the Vietnam War. They were subsequently convicted of disorderly conduct. In 1978, a women's group laid a wreath dedicated to all the women raped and killed during war, and movements for feminism, gay rights, and peace used the occasion to draw attention to their respective causes at various times during the 1980s.
