colonial authorities following the determination of the British Government to upgrade the colonial defences of the empire post 1870s. The battery's form and armament is a culmination of current military wisdom, based on the advice of leading military British advisors such as Scratchley and Jervois. Their advice and directives led to the continual advancement of the defensive capability of Sydney and its rival colonies, based on the best options to fortify Australian ports in an era of increasing mechanisation and military threat (real or implied). The place is important in demonstrating aesthetic characteristics and/or a high degree of creative or technical achievement in New South Wales. The Battery, if found to retain its original 9.2" gun, hydraulic mount, associated movable items, and ancillary rooms and quarters, provides a unique opportunity to document 1890s military technology and defence fortification systems. The potential integrity of these elements is unique in the Australian context and would provide one of the few opportunities for detailed scientific analysis of such a large coastal naval fortification system (9.2") in the world. The place has potential to yield information that will contribute to an understanding of the cultural or natural history of New South Wales. Due to the presumed integrity of the reinforced concrete gun pit, associated rooms, and the probability of the entire gun and mechanism being extant, the Ben Buckler battery site has the potential to provide significant insights into late-Victorian defence technologies. The value of the site lies in its burial and retention, in comparison to the two (2) other NSW sites, and those in Queensland, Victoria and South Australia, that have more commonly been decommissioned and stripped of armaments and fittings. In world terms, the Ben Buckler site is important as a comparative example to other British defence facilities established throughout its colonies in the late 1870s - turn of the century. The place possesses uncommon, rare or endangered aspects of the cultural or natural history of New South Wales. Due to the presumed integrity of the reinforced concrete gun pit, associated rooms, and the probability of the entire gun and mechanism being extant, the Ben Buckler battery site has the potential to provide significant insights into late-Victorian defence technologies.
