The Surveyors Gallery features a collection of surveying instruments originally belonging to HF Halloran, an influential town planner and developer in New South Wales during the first half of the 20th century. His son Warren has developed this collection into one of international significance that contains surveyors instruments that reflect the major changes in land use from the Industrial Revolution to the development of land after European settlement in Australia.
These instruments show the skill of the scientific instrument makers and reflect the changes in design and technology to provide accuracy with instruments that could be portable and survive quite hostile conditions.
