One piece that I didn't link to a few weeks back, as I was in Sydney that weekend and didn't get to see the paper, was an essay by Kerryn Goldsworthy published in "The Australian" newspaper, titled "On Her Selection".
In the piece, the author poses the question: "If, on this Australia Day weekend, an international visitor asked you for a crash course in Australianness, what would you suggest they read? What are the books whose accounts of what it means to be Australian have stayed with you? Would they be A Town Like Alice? Wake In Fright?, Possum Magic?"
And then proceeds to answer it. I'll let you find what what she recommends. Be ready for something of a surprise near the end. One of her selections was published quite recently.
