A swagman (also called a swaggie, sundowner or tussocker) is an old Australian and New Zealand term describing an underclass of transient temporary workers, who travelled by foot from farm to farm carrying the traditional swag (bedroll), particularly during the Depression of the 1890s.
So "Swag" is goods or possessions, and has only recently come to be associated with prizes and tchotchkes (small toys, gewgaws, knickknacks, baubles, or trinkets) that are given away by radio stations.
This is not what Tim Tex is asking about
