In 1836, the surveyor Thomas Watson returned to area and used Bald Hill as the principal trigonometric reference. Watson was to map out a number of lots in the area including the western boundary for Beverley town site. Two of the lots surveyed were Avon location 14 with , and Avon location K with ; location 14 was given to Captain Mark Currie, Fremantle Harbour Master, while location K was given to Stirling. Stirling as Governor and Currie as harbour master were not paid salaries by the colony but given land grants as compensation for their services. In 1978, surveyors using current equipment were engaged to determine the exact location of these original holdings, and commented on the remarkable accuracy of Watson's survey 142 years before.
