A replica of Sturts boat at Tibooburra. In August 1844 explorer Charles Sturt set out from Adelaide on an epic journey to find an inland sea. He also wanted to prove that a great river or mountain range divided the continent. He took with him a party of 15 men, 200 sheep, 11 horses, 32 bullocks and seven carts. Indeed, so confident was he of finding this sea he took a 22-foot sailing boat and two sailors to crew it.
