In the early 1800s the Great Australia Unknown would be slowly revealed, in part by formal government expeditions, but also by runaway convicts, little known and privately funded explorers, and pastoralists seeking both knowledge of what lay beyond and land to occupy.

Through extensive research, and with engaging storytelling, The Other Side of the Mountain brings three of these men’s stories together into a single enthralling narrative: Ralph Entwistle, runaway convict and bushranger who led a brief and briefly successful rebellion against the brutality of the convict system on the fringes of New South Wales’ western plains; John Horrocks, an English textiles magnate who brought most of his village from the north of England to Adelaide and beyond, and who was the first to explore Australia’s parched interior by camel, a decision that cost him his life; and Horace Wills, a printer, rebel, overlander, pastoralist and politician who gave up everything to push the frontier back in the far north of the continent.
