The Archer brothers were among the earliest settlers in Queensland. They were explorers and pastoralists. Seven sons of William Archer, a Scottish timber merchant, they spent varying amounts of time in the colony of New South Wales, mainly in parts of what later became Queensland. A substantial number of locations in Queensland were either named by or for them. They were, in order of birth:
The first of the Archer brothers to settle in Australia was David, who arrived in Sydney in 1834. He was joined by William and Thomas in 1838. Together, they planned to seek pastoral land on the Darling Downs. Delays meant they would be too late to secure good land, so this venture did not proceed. In 1841 David and Thomas, joined by their brother John, travelled to the upper reaches of the Stanley River, an eastern tributary of the Brisbane River. There, near present-day Woodford, they established Durundur Station, a holding of 200 square miles (520 km2), which is equal to 128,000 acres (51,800 ha). Durundur is an aboriginal name for the Moreton Bay Ash (Eucalyptus tessellaris) The Archer name is seen in the main street of Woodford, and in Mount Archer about 12 kilometres (7 mi) to the west.
Charles Archer arrived in Australia in 1841, and joined his brothers at Durundur in 1843. He was accompanied by the explorer Ludwig Leichhardt, who stayed at Durundur for several months until early 1844. The country at Durundur proved unsuitable for sheep, leading the brothers to take up two runs further west in 1845. One of these was Cooyar, a holding of 71,660 acres (29,000 ha) on Cooyar Creek, a western tributary of the Brisbane River, near present-day Cooyar, 90 kilometres (56 mi) north of Toowoomba, on the New England Highway. The other was Emu Creek, a holding of 32,000 acres (12,950 ha) on Emu Creek, another western tributary of the Brisbane River.
