The Queensland Acclimatisation Society (QAS) was an acclimatisation society based in Brisbane, Queensland, Australia which operated from 1862 to 1956. Its primary interest was in the introduction of exotic plants to Queensland, both for economic and ornamental purposes.
From its inception in 1862 at the instigation of the Governor of Queensland, Sir George Bowen, the Queensland Acclimatisation Society focussed on contributing to the development of Queensland's fledgling agricultural industry. It imported plants that had commercial potential and conducted experiments to determine if they could be adapted to Queensland's tropical and sub-tropical climate. Plants researched included sugar cane, bananas, cotton, apples, pineapples, pasture grasses, maize, olives, mangoes, pecan nuts and macadamia nuts. Many of these became important agricultural crops in Queensland.
The society fulfilled a supporting role to the sugar industry from 1863. In that year, the Queensland Acclimatisation Society began importing cane from Mauritius and New Caledonia and distributing it to growers. Until well into the 20th century, they continued researching into the crop, importing and distributing new varieties and experimenting with propagating cane from seed and artificially cross- fertilising canes. They produced a popular variety of sugar cane, Q813, which was known for its resistance to disease and was still in use as late as 1926.
Before the establishment of the Department of Agriculture, the society acted as a government advisory body on agricultural matters. Until at least 1888, it was dependent on government funding and regarded itself to all intents and purposes as a government institution. The society contributed to the establishment of the Queensland Herbarium, the Kamerunga State Nursery, and the Queensland Forestry Department.
Between 1914 and 1915, the society closed its first gardens at Bowen Park and moved its operational base to a 100-acre property on the south bank of the North Pine River at Lawnton (the Acclimatisation Society gardens, Lawnton). The society had begun to lose Government support after the establishment of the Department of Agriculture in 1887 and this, together with the expansion of the adjoining National Association grounds (the present Brisbane Exhibition Grounds), meant that Bowen Park was no longer viable. No buildings associated with the Queensland Acclimatisation Society remain extant at the Bowen Park site.
