G'day Bob, it is strange and maybe Charley pointed us in that direction, that I see in the song there was a frustration that "I have stuck it out," maybe coloured by an abortive move to Western Australia, maybe he saw his roots in Australia and not in "the old country" of which he wasn't really part of but saw his literary mates ship out for the "greener grass". I think if there was a resentment it was because maybe he felt he had to follow the others rather than wanted to.
