first sugarcane crop in the Mackay region. John Ewen Davidson and T. H. Fitzgerald built the first production sugar mill in 1868. Most of the labour on the sugar plantations was provided by South Sea Islanders. The first 70 of these workers arrived in Mackay on 12 May 1867 aboard the Prima Donna. and were sent to work at Fitzgerald's Alexandra Plantation. By the mid-1880s there were over 30 sugar plantations and 26 sugar mills in the Mackay region. Over one third of the 6000 inhabitants were South Sea Islander labourers. On Boxing Day 1883, a race riot occurred between members of these workers and some of the European population at the Mackay racecourse. Hundreds of people on both sides threw bottles at each other until around 50 Anglo-Australian horsemen wielding stirrup irons galloped into the group of Islanders, knocking them down with their improvised weapons and riding over them. Officially two Islanders were killed but it was believed a greater number later died of injuries. One white man involved, George Goyner, was found guilty of assault and sentenced to two months in prison. Around thirty Islanders were also imprisoned. In 1918, Mackay was hit by a major tropical cyclone causing severe damage and loss of life with hurricane-force winds and a large storm surge. The resulting death toll was further increased by an outbreak of bubonic plague. Communication links into Mackay were destroyed. The outside world did not learn of the Mackay cyclone until five days after impact, leading to some speculation the city had been completely destroyed. The disaster remains one of the most destructive cyclones to strike a populated centre in Australia. The foundation stone of the Mackay War Memorial was laid on the river bank on 18 November 1928 by the mayor George Albert Milton. It was unveiled on 1 May 1929 by the mayor. Due to flooding, the memorial was relocated to Jubilee Park in 1945. Due to the construction of the Civic Centre, it was relocated to another part of the park in March 1973. The largest loss of life in an Australian aircraft accident was a B17 aircraft, with 40 of 41 people on board perishing, on 14 June 1943, after departing from Mackay Aerodrome, and crashing in the Bakers Creek area. The Rats of Tobruk Memorial commemorates those who died at and since the Battle of Tobruk. The memorial was dedicated on
