This encyclopedic edition of Australia's national dictionary is truly international and uniquely Australian. With the inclusion of expanded encyclopedic notes for many entries, it is able to satisfy the user's need for information at a level that is unusual in a standard dictionary.

The second edition has been expanded to update and extend the encyclopedic coverage, and to include thousands of new words and senses, in particular those relating to the environment and climate change and to increase and update the encyclopedic coverage.
