The Henker Family Graves are located within a Macadamia Plantation towards the western end of Henkers Road in the suburb of Oakwood, approximately seven kilometres northwest of the Bundaberg CBD. The grave site is cordoned off by a rope strung between the corner posts of a former wrought iron fence surround. There are three headstones in form of decorated stelae arranged in a row.

McLucas (nee Watson) and her son, William Watson, were early settlers in the Bundaberg district. William selected over 100 acres, bounded by Splitters Creek, in 1871, making him (and his mother) some of the earliest settlers in the region, given that the town of Bundaberg had only been surveyed two years earlier. The property was called Carnamoyle, after Carnamoyle in Ireland. Watson went on to establish a successful agricultural implement manufacturing, blacksmith and wheelwright business in 1880. Mary died in 1879 and was buried on the property. Charles Henker (d1894) and Wilhelmine Henker (d1901) are also buried on the property; it is unclear whether they were related to the Watsons, or if they were subsequent owners of the property.
