History/Origin The name Calvert River originates from explorer Ludwig Leichhardt's 1845 overland expedition from Queensland to Port Essington in the Northern Territory. On 8 September, the expedition camped beside a small river shaded by Pandanus and tea-trees, with a series of deep waterholes still holding fish late in the dry season. In his journal, Leichhardt initially noted this river as the Abel Tasman River, referencing early Dutch navigators, but subsequently crossed out this name in his field notes and wrote: "I named this river the "Calvert," in acknowledgment of the good services of Mr. Calvert during our expedition, and which I feel much pleasure in recording."

James Snowden Calvert (1825-1884) was born on 13 July 1825 in Otley, Yorkshire. Calvert migrated to Australia in 1841 with his brother William, meeting Ludwig Leichhardt on the outward journey. He later joined Leichhardt in 1844 on the ambitious overland expedition from Brisbane to Port Essington. Although physically not robust, Calvert endured the harsh conditions of the journey, including a serious conflict with Aboriginal people in the Gulf Country. Despite these hardships, his amiable nature earned Leichhardt's respect; in a letter to Germany, Leichhardt noted Calvert as the only member who "behaved perfectly, with few exceptions". After the expedition, Calvert became manager of Cavan Station near Yass. He developed a strong interest in botany, earning medals at international exhibitions for his botanical contributions. In 1869, he married Caroline Louisa Waring Atkinson, a noted naturalist and writer. Following her early death in 1872, Calvert lived a retired life until his death in Sydney on 22 July 1884.

While Leichhardt?s diary provides this first hand account, later research by historian and bushman Glen McLaren in the 1990s suggests that the river Leichhardt named the Calvert may correspond to what is now known as Sandy Creek. McLaren's extensive fieldwork retracing the expedition route, supported by GPS and Leichhardt's maps, helped clarify the location of many named features from the expedition.
