The locality name derives from the
Caboonbah Homestead built by
Henry Plantagenet Somerset. The name derives from the
Kabi language "cabon gibbah" meaning
big rock. It was added to the
Queensland Heritage Register on 12 December 1996. Caboonbah Homestead was on Esk-Kilcoy Road, now with the neighbouring locality of
Lake Wivenhoe. The wooden structure was designed by Somerset's wife Katherine Rose Somerset, the daughter of
David Cannon McConnell and
Mary McConnel (nee McLeod) who founded the
Cressbrook Homestead. The church was built by Lars Andersen. It opened in 1905 to serve the local farming community. It is located on Cressbrook-Caboonbah Road (), now within the neighbouring locality of
Mount Beppo. == Demographics ==
