What was Augustus Gregory's purpose?

Answer 1

Augustus Charles Gregory explored for several reasons. First and foremost he hoped to find new land which could be used for agricultural purposes.

Gregory also led an expedition to search for missing explorer Ludwig Leichhardt. On this journey, he headed west from Juandah Station, crossed the Warrego and Barcoo Rivers but was forced by drought to abandon the search and travel south to Adelaide. Although he found no evidence of Leichhardt's expedition, he did help mark out the southern boundary of Queensland.

Gregory also proved once and for all that Eyre's theory of the great inland horseshoe shaped lake was not true, and that the lake was a series of saltpans.
