Peter Egerton Warburton (1813–1889) — Australian explorer and public servant

Career and appointment

After arriving in South Australia, Warburton entered colonial service and was appointed to senior policing duties. He was later employed by the South Australian government to lead exploratory missions and to succeed earlier survey efforts. The government specifically asked him to replace Benjamin Herschel Babbage, whose progress they considered too slow, leading Warburton to inherit and continue attempts to penetrate the interior (Benjamin Herschel Babbage).

Major expeditions and discoveries

Between the mid-1850s and the 1870s Warburton mounted several expeditions into arid regions north and central to South Australia. His fieldwork documented terrain, water sources and passes that had blocked previous northward efforts. Notable achievements include:

• Locating a corridor through the ring of salt lakes north of Adelaide, which had impeded further exploration.
• Visiting and recording artesian springs later referred to as Coward Springs; he described the local geology and water supply (artesian springs).
• Exploring ranges in central and northern South Australia, notably naming the Davenport Range in honour of Sir Samuel Davenport, a prominent local politician (Sir Samuel Davenport).

The 1872 central-to-coast crossing

Warburton's most famous journey began from the centre of the continent and in 1872 reached the west coast, making him widely reported as the first European to cross Australia from Alice Springs to the coast of Western Australia. The route took his party across extremely difficult country, including the Great Sandy Desert. Records from the expedition describe severe privation: Warburton sustained serious injuries and lost sight in one eye, supplies ran low, and the party was forced to consume most of its camels to survive. At times Warburton was reportedly so weak he completed portions of the journey tied to his camel for support.

Guides, survival and recognition

Contemporary accounts emphasize that the party's survival depended heavily on the skill and knowledge of their Indigenous guide, often named Charley in expedition reports. Local expertise in locating water and reading country was decisive in completing the crossing. For his endurance and service Warburton received official recognition: he was appointed a Companion of the Order of St Michael and St George (CMG) and awarded a government gratuity.

Warburton's expeditions contributed detailed observations of arid landscapes and water resources that informed later exploration, settlement and mapping. Modern assessments place his achievements alongside the broader, often difficult and contested history of European exploration in Australia, which depended on both colonial resources and Indigenous knowledge.

For further context and archival material see contemporary reports and government correspondence relating to his appointments and expeditions: service records, exploration summaries, and administrative papers held by the South Australian government. Additional commentary on Babbage and Davenport is available through historical summaries (Babbage, Davenport). Contemporary expedition narratives and later historical studies discuss the 1872 crossing and the role of Indigenous guides (Western Australia reports, desert accounts, camel logistics, honours).
