Cornubia is situated 28 kilometres (17 mi) south-east of the Brisbane central business district. Many street names reflect its lush bush setting (e.g. Sugarwood, Parkview). The Beenleigh–Redland Bay Road runs through the south of the locality from west to east.

By the early 1980's residential development was apparent.
