In 1840, about six camels were shipped from Tenerife to Adelaide, but only one survived the journey to arrive on 12 October that year. The animal, a male called Harry, was owned by the explorer John Ainsworth Horrocks. Harry was ill-tempered but was included in an expedition the following year because he could carry heavy loads. The next major group of camels were imported into Australia in 1860, and between 1860 and 1907 10 to 12 thousand were imported. These were used mainly for riding and transport.
