A colloquial Australian term. Same as Hobo in USA. Someone who wanders from
place to place working for his tucker, whose possessions fit into his swag (Ofttimes his blanket tied by the corners and
slung over his shoulder on a stick) The song
Waltzing Matilda was written about a Swagman who stole a sheep, but this is not the norm for the Swagman., He was a traveler, for whatever reason.
