The Surveyors Gallery contains Warren Halloran's world-standard collection of surveying instruments, some of which were owned by his father, Henry Halloran (1869-1953) a surveyor and land developer.
The collection includes a theodolite owned by Isambard Kingdom Brunel (1806-1859), Britain's foremost engineer of the 19th century, and other instruments dating back to earlier centuries.
In the Surveyors Gallery there are also several portraits of Sir John Jervis (1735-1823), after whom Jervis Bay was named. There are also two 200 year old etchings showing the sea battle of Cape St Vincent on the 14th of February 1797.
Also in the Surveyors Gallery are two large sea chests and two logs of lignum vitae, and in the lobby beyond are whaling implements.
