|This is the final issue in the Nature of Australia definitive series. The series, which started in 1996, has depicted different Australian habitats using illustrations of specific environments that are representative of the habitat and images of the flora and fauna found within the habitat.|
The series has featured eucalyptus forest, wetlands, coastal and desert habitats. The fifth, and final habitat, rainforest as exemplified by the Wet Tropics in far north Queensland, was introduced with Nature of Australia: Rainforest (February 2003).
The butterflies on the stamps are all found in the Daintree region of the Wet Tropics.
