Thanks for that AC.
It comes as no surprise that Bob had already posted its original text, as he has a considerable set of resources to hand. The text I posted is as I have sung it and I probably learned it around campfires from other bushwalkers who may have learned it from John Meredith's Penguin edition of Australian Folksongs, prior to the Bushwackers or even Dave de Hugard, who is a towering influence on such things.

Cheers, Rowan
