 Biri (Birri) is a language of Central and North Queensland. Biri refers to a language chain extending from Central Queensland towards Townsville and is often used as a universal name for other languages and/or dialects across the region. The language area includes the towns of Bowen, Ayr, Collinsville and Nebo.
 The first British exploration of the area occurred in 1839 during the third voyage of HMS Beagle where Captain John Clements Wickham travelled 10 miles up the waterway later known as the Burdekin River. His progress was stopped by a fishing weir built by the local Aboriginal people that spanned the river.
 In 1843, during the surveying voyage of HMS Fly, Lieutenant John Ince, Joseph Jukes and Frederick Evans sailed up the river near to where the town of Ayr is now located. They encountered two large tribes of Aboriginal people with whom they had friendly interactions, exchanging items and participating in an apparent Welcome to Country ceremony. Artist, Harden Sidney Melville was also present, later drawing a depiction of the meeting.
 Shipwreck survivor James Morrill lived with Aboriginal people in the region for seventeen years from 1846 when he was washed ashore on a makeshift raft. Morrill lived a traditional Aboriginal lifestyle and later made a culturally and historically important record of his experiences.
 In 1859, Henry Daniel Sinclair, James Gordon and Ben Poole conducted a sea voyage that examined the mouth of the Burdekin River. They travelled about 8 miles up the river but were afraid to explore further as they were wary of the resident Aborigines and had limited firearms.
 George Elphinstone Dalrymple led an overland expedition to the area in 1859 looking for land acquisitions and he returned again in 1860 as the head of a seagoing exploratory party. Dalrymple had several violent encounters with the local Aboriginal people during these expeditions. In 1862, Dalrymple made another journey to the lower Burdekin region concluding that the "richly grassed open forest country" would become "a most valuable addition to the pastoral and agricultural resources of the colony."
 The area was opened up to pastoral squatting leases in 1861 and in that year Edward Spencer Antill (who was a son of the distinguished colonist Henry Colden Antill) arrived in the region to take up land. In 1862, he selected a large area of land along the lower Burdekin River for a sheep station which he named Jarvisfield after the Antill family estate near Picton. Groups of armed settlers and Native Police started to force the Aboriginal people off the land around this time, with James Morrill documenting a massacre of a resident Burdekin River tribe. E.S. Antill bore a life-long scar on his forehead from a boomerang thrown at him during one of these episodes of frontier violence. Morrill attempted to negotiate a treaty between the British and the Aborigines whereby the coastal area on the north side of the Burdekin would be a reserve for the Indigenous people but this was ignored by the authorities.
 After E.S. Antill had become established, other colonists took up land in the region, namely John Graham MacDonald who formed the Inkerman Downs property with the financial backing of Robert Towns, and Edward Cunningham who formed Woodhouse station. In retribution for murders and cattle spearing, punitive expeditions by the Native Police led by Lieutenant John Marlow would "disperse" the local Aboriginal population.
 A township, named Wickham, was formed in the region in 1864 but was destroyed in 1870 during a flood. Robert William Graham formed the Lilliesmere run in 1876 and in 1881 the township of Ayr was laid out on this property by surveyor Ellis William Lymburner.
 Ayr was named after the Scottish town of Ayr, the birthplace of nineteenth-century Queensland Premier, Sir Thomas McIlwraith.
 Ayr Post Office opened on 25 August 1883.
 Large scale cultivation of sugarcane began in the region in 1879 with the formation of the Burdekin Delta Sugar Company through the partnership of local landholders Robert William Graham and Archibald Campbell MacMillan. Their plantation was called Airdmillan and in 1883 the Airdmillan sugar mill was built. Both the mill and the plantation became financially unviable in 1885 after the repatriation of kidnapped South Sea Islander labourers working on the plantation. Of the 532 Islanders brought to Airdmillan, 128 or 24% had died by 1885. In the 1890s, Airdmillan was subdivided and today much of the town of Ayr is located on what was once part of the Airdmillan estate. The nearby locality of Airdmillan is named after the plantation.
 Other colonists also established plantations and mills in the region during the 1880s. James Mackenzie formed the Seaforth estate and mill, while Colin Munro built the Drynie mill. In 1882, John Spiller and Henry Brandon established the Pioneer plantation which was soon sold to the Drysdale brothers. The Drysdales built the Pioneer Mill in 1884 and later constructed the Inkerman Mill in 1914. Charles and John Young formed the Kalamia plantation in 1882, the Kalamia Mill being operational two years later. Much of the labour on these plantations during the early years was performed by South Sea Islanders, many of whom died in the first year after being shipped in. At Kalamia and Pioneer, the death rate was 14%, and at Seaforth it was 26%. Islander labour in the region was discontinued in the early 1900s.
 The Pioneer, Kalamia and Inkerman mills are still operational and are owned by Wilmar Sugar.
