Sydney's first May Day march was in 1891, while in Melbourne it was on 30 April 1893. A combined union committee organized the annual May Day celebrations in Melbourne. The first May Day in Melbourne occurred in 1893, but this organizing committee datesĀ· from the 1930s. Several prominent labour stalwarts have held the secretaryship of the committee including John Arrowsmith in the 1960s and early 1970s..
