Although smaller than the gold rushes of Victoria and New South Wales, Queensland had its own series of gold rushes in the later half of the nineteenth century. In 1858, gold was discovered at Canoona. In 1867, gold was discovered in Gympie. Richard Daintree's explorations in North Queensland led to several goldfields being developed in the late 1860s. In 1872, William Hann discovered gold on the Palmer River, southwest of Cooktown. Chinese settlers began to arrive in the goldfields, by 1877 there were 17,000 Chinese on Queensland gold fields. In that year, restrictions on Chinese immigration were passed.
