The six Mega creatures featured on the stamps are:
- * Genyornis newtoni, 55c, a large bird reminiscent of emus and cassowaries but in fact more closely related to ducks, geese and swans.
- * Diprotodon optatumm, 55c, a giant wombat with two prominent projecting teeth.
- * Thylacoleo carnifex, 55c, harking from possum ancestry but a more destructive and predatory version.
- * Thylacinus cyanocephalus, 55c, or more commonly known as the Tasmanian Tiger.
- * Procoptodon goliah, $1.10, probably the largest of all kangaroos and weighing upwards of 200kg.
