And I reckon the only surprise on that list would be the placing of Winton's Breath. It's only been out a year or so, and yet came in at number 4. Winton has another novel in the top twenty: Dirt Music in at number 13, and White also had The Vivisector at number 14.
In all, 290 novels were nominated and ABR has supplied the full list. If you were looking for a definitive list of Australian fiction you could do worse than check this out.
