G'day BBC,I can dig out a few you won't have elsewhere. There is a lovely cautionary tale called The Sparrow and the Emu Egg in my anthology Singabout - Selected Reprints and a recently collected children's song that I transcribed and published in Singabout called The Possum Song.
I will look for a few more (there may be some suitable ones in some unpublished material I hold of the late Stan Wakefield (I am looking at it with his son Brian) ... as well as his previously published The Kookaburra Laughed.
