My copy arrived in late December, but stuck on Christmas Island there isn't much I can do at present in respect to mammal-watching.
The book is broken up into 10 chapters, one for each state or territory plus oceanic islands and external territories, and boat-based whale and dolphin-watching.
Each state is broken into smaller sections and various locations numbered (the same as "Finding Australian Birds" by Dolby and Clarke), and for each location Key Species and other possibilities are listed first before specific details on the best place to find each.
The Oceanic Islands and External Territories chapter covers Lord Howe, Norfolk, Christmas, Cocos (Keeling), Heard and Macquarie Islands and the Australian Antarctic Territories. The chapter on boat-based cetacean watching lists all the towns/cities that have this activity, and details the species usually seen.
This is followed by colour plates of many of the commoner species, a mammal-finding guide that lists every species and where to best find them (with references back to the main body of the book), and some appendices: Introduced Mammals; Directory; Glossary; and Glossary of Botanical and Habitat terms.
The Directory appendix (not sure why it's called that) includes advice for travellers includes Planning Your Trip, Air Travel, Timing, Getting Around, Accommodation, Climate, Natural Hazards, Books on Australian Mammals, websites, Tour Operators, and Wildlife Friendly Accommodation.
I haven't used the book yet (apart from the small part on Christmas Island) but will when I return to the mainland. However, it looks really good and for me it's gonna be very good value for money.
Potential buyers should be warned though - the rarer the animal the more likely the references will be that your species "is often seen" at a particular location, but there are never any guarantees (which is only common sense).
