‘A man out of employment’
In ‘The Romance of the Swag’, in Children of the Bush (1902), Henry Lawson, who had carried swag himself ‘for months out back’, called Australia ‘the land where a man out of employment might shoulder his swag in Adelaide and take the track’. He explains how to roll one: a tent fly or calico, blankets ‘blue by custom’ (hence ‘bluey’), spare clothes in the core, three or four straps. The word is older than his essay: by the 1830s Australians used ‘swag’ for a bushman’s belongings, and ‘swagman’ dates from the gold rushes of the 1850s.
