There are 64 genera and 364 species of Coccinellidae described from Australia (Australian Faunal Directory, 2025)

A guide to the beetles of Australia by G. Hangay & P. Zborowski (CSIRO Publishing, 2010) lists the family's characteristics:

body broadly ovate, highly convex, usually glabrous but some finely pubescent, 1-7 mm in length
yellow to black, often bicoloured or spotted, some with metallic shine
head deflexed, concealed from above by prothorax
antennae short, usually 11-segmented, including a 3-segmented club
tarsal formula [number of tarsal segments on front, middle and hind legs] 4-4-4, but appears to be 3-3-3 as the third segment is minute and hidden

Adults and larvae of most species are predators of aphids, mealybugs, scales or other small insects and mites. Exceptions are Epilachna species, which are herbivorous on Cucurbitaceae and Solanaceae, and Illeis galbula which feeds on powdery mildews (Australian beetles, Vol. 1, eds. J.F. Lawrence & A. Slipinski, CSIRO Publishing, 2013)
