Yeah OZBuzz, its Honey and Pollen Flora, by Alan Clemson, 1985 by Inkata Press. ISBN 0 909605 33 5. It was published by the then NSW Department of Agriculture, Alan Clemson was their Head Apiary Officer for many years, the book is stuffed full of info and colour photos. They are talking about a reprint - complicated by the fact that the Eucalypts of 1985 have now been split up by botanists into different scientific name families (is it genera? I never remember that stuff, its all Black box, Ironbark or yellow stringybark to me).
I got my copy on ebay, for $45 - but its a hard book to get.
