Loved your post! It brought me some new publisher sites, and reminded me of great ones I'd forgotten.
New Frontier is another excellent publisher, mostly of picture books and children's titles, some educational. They have great support in their teacher notes, which include discrete learning objectives for each title.
Thanks, Susan, for supporting your fellow Aussies and their fine work in the publishing field. Perhaps this will encourage others to represent their own countries!
When you get the opportunity, be sure to check out Susan's excellent blog at http://thebookchook.blogspot.com/. Book reviews, giveaways, and lots of other "good stuff" for teachers, parents, and lovers of children's books.
