a while back I was researching the word bluey and discovered it's used in Oz to refer to a swagman's bundle and in the phrase "to hump bluey", to travel with a swag, to hit the trail. I also found that bluey is apparently used as a slang term for a red-headed man! can anyone confirm this? or explain it??

p.s. - in response to J's note, without increasing the post count, I believe my original question predates the influx of Ozzies!
