The range of the Native dung beetle is over most of southeastern Australia. It can be found from southern Queensland to Tasmania and South Australia.
Onthophagus australis is most often found in manure in open pastures.
The most distinctive feature is the segmented antennae. This antennae forms a club containing three to seven leaves. These leaves can be expanded or folded together to form one compact club. The beetle is brightly colored. The surface of the dung beetle's head varies, but it is short, broad, and partially deflexed. The eyes are oval and prominent. The wings are large and well-developed.
Native dung beetles emerge mainly during late summer into fall. For the first several weeks they are in a "maturation feeding stage". A majority of beetles are in the adult stage during the winter. Ocassionally eggs are laid in the fall, which then emerge in spring.
It is unclear what the exact function of food balls is in the life cycle of the Native dung beetle. While most beetles store dung in food chambers before reproduction, the native dung beetle forms food balls during reproduction. This leads to O. australis being the only beetle found in dung when the first population of bush flies begin oviposition in the spring.
Native dung beetles are not in danger of extinction.

A terrestrial biome. Savannas are grasslands with scattered individual trees that do not form a closed canopy. Extensive savannas are found in parts of subtropical and tropical Africa and South America, and in Australia.
A grassland with scattered trees or scattered clumps of trees, a type of community intermediate between grassland and forest. See also Tropical savanna and grassland biome.
A terrestrial biome found in temperate latitudes (>23.5° N or S latitude). Vegetation is made up mostly of grasses, the height and species diversity of which depend largely on the amount of moisture available. Fire and grazing are important in the long-term maintenance of grasslands.
