"Demarr arrived in New South Wales in 1839 on the immigrant ship Heber, having escaped from the drudgery of farm life in Yorkshire and the 'austere rule' of his father. He intended to gain experience working in Australia, with a view to investing at a later stage. He describes the inadequacy of the the emigrants' guides, which he relied on for provisioning, and gives a graphic description of the hardships of the voyage and the character of his fellow passengers. He travelled extensively in Victoria, New South Wales and Queensland over the next five years, working as a storekeeper in Queanbeyan, as a stockman on a cattle station in the Snowy Mountains, as a shepherd in New England, and as a drover over landing cattle from Sydney to Port Phillip. Demarr writes vividly of the hospitality, transitory friendships and isolation of the bush, of the economic and social conditions of outback Australia, and of the terrors of travelling alone. In Queensland, he was unable to prove he was a free immigrant and was briefly detained as an escaped convict. A man of independent attitudes, he is contemptuous of British law and the transportation system. He expresses great sympathy for the convicts, with whom he often worked, and the Aborigines, concluding that 'what we call the civilisation has been no boon to the black natives of Australia, and to their mind must be associated with gunpowder, poison, hunger, disease and extermination'. Demarr set sail from Sydney for South America and England in 1844" (Walsh and Hooton 52).
