I did know about Banjo Paterson, (Waltzing Matilda, Man From Snowy River) but I didn't know anything about Gwen Harwood, or a host of others.
If you google Harwood you get tons of school-essays. I guess she's required reading down under. In one such essay I found this sentence:
"The poetry of Gwen Harwood is very malleable."
You can twist it into shapes -
household gods or prancing apes,
in airtight hermeneutics with Houdini-like escapes.
