Willamulka is a locality at the top of Yorke Peninsula in South Australia. It is on the road between Kadina and Bute. Its name is derived from an Aboriginal word meaning "shiny green stone" (copper ore).[1]
Willamulka is also located on the former railway line between Kadina and Brinkworth. It closed to regular traffic in 1993. Tourist trains last used the line in 2009.
The Willamulka Bible Christian church opened on 21 December 1885 and became a Methodist church in 1901. It closed in May 1977 and is located on the corner of Willamulka and Church Roads, east of the modern boundary of the locality.[3]
