Kojonup is a town 256 kilometres (159 mi) south-east of Perth, Western Australia along Albany Highway in the Great Southern region.

Specifically, the Noongar people of Kojonup today are descendants of the Kaneang language group and their neighbours, such as the Koreng, Pinjareb and Menang.

[citation needed] The first European in the area was surveyor Alfred Hillman who arrived in 1837 and had been guided to freshwater spring by the Noongar people.

The site was an important staging place on the road to Albany, and in 1837 a military post was established there for the protection of travellers and the mail.

The early economy of the town was initially dependent on cutting and transporting sandalwood and kangaroo hunting[11] but by the mid-19th century the wool industry began to boom and by 1906 the shire had 10,500 sheep.

[14] The Marsh v Baxter case has put Kojonup at the epicentre of the battle in Australia of organic versus genetically modified agriculture.
