The St Lawrence police station and courthouse, constructed in 1878, the second to be built on the site and the cell block, constructed by 1880, are situated in a prominent position overlooking the St Lawrence Creek, located on the site of a government reserve which has served the community as part of the justice system since 1863.
Few early timber police station and courthouse buildings survive and the St Lawrence police station and courthouse building is significant for its rarity as one of the earliest, intact, extant examples of this type of building. As a single-storey, timber government building, with drawings prepared by the Office of the Colonial Architect, it also has aesthetic significance due to the simplicity and symmetry of design of the building.
