One of the first May day marches in the world took place during the strike on May 1, 1891 in Barcaldine. The Sydney Morning Herald reported that 1340 men took part of whom 618 were mounted on horse. Banners carried included those of the Australian Labor Federation, the Shearers' and Carriers' Unions, and one inscribed 'Young Australia'. The leaders wore blue sashes and the Eureka Flag was carried. The Labor Bulletin reported that cheers were given for "the Union", "the Eight-hour day", "the Strike Committee" and "the boys in gaol". It reported the march:
"In the procession every civilised country was represented doing duty for the Russian, Swede, French, Dane etc, who are germane to him in other climes, showing that Labor's cause is one the world over, foreshadowing the time when the swords shall be turned into ploughshares and Liberty, Peace and Friendship will knit together the nations of the earth."
