I've added all four of the books I voted for to my TBR list; thanks to Bookpossum for her intriguing selections.
I'm trying to think of Aussie writers I've read and I have read several novels by Patrick White (picked the Penguin editions off a remainder table years ago) and have no desire to return to him! Of the list of ten-before-you-die books I've read only two:
The Book Thief and
Picnic at Hanging Rock.
I've read books by Thomas Kenneally and Robert Hughes and Peter Carey and for those of us who've read/are reading
Sleepwalkers, there's another Australian. I notice we've all avoided naming Neville Shute.

Oh, and Miles Franklin and Mrs. Aeneas Gunn.
For those who like picture books, Mem Fox's books are delightful.
I admit, not a very creditable list! Thanks again to Bookpossum. Perhaps others will do us a similar favor?
