 The first European known to have visited the Kulin area was Captain John Septimus Roe, Surveyor General of the Swan River Colony on his 1848-49 expedition to examine the south coast.He encountered a group of Aboriginal people 34 miles east of Nalyaring (near Brookton) who guided the expedition party to several water sources, including the Kulin Rock soak, before leaving the party at Yeerakine Rock (just south and east of Kondinin) as this was the limit of their territory.These guides used the name "Coolin" to describe the area now known as Kulin Rock.
