These frogs are known as the Southern Frogs and are sometimes placed in the Leptodactylidae family, a family of frogs found in both South and Central America. (This is a matter of some controversy among herpetologists). In Australia, they are represented by over 100 species in 21 genera.
The family Myobatrachidae is an extremely variable one and members of this family have some of the world's most unusual frog life cycles. Some lay eggs on land, waiting for rains to flood the area at which time the tadpoles hatch. The Sandhill Frog gains its water from damp sand and lays eggs which hatch into fully formed frogs. Perhaps most spectacularly, the Gastric Brooding Frog, an entirely aquatic frog, swallows its eggs to incubate them in its stomach and vomits forth fully formed froglets.
The family Myobatrachidae is represented in Victoria by 22 species in 10 genera, ranging from the tiny Sloane's Froglet, Crinia sloanei, at little over 20mm, to the Great Bullfrog, Limnodynastes interioris, and the Great Burrowing Frog, Helioporus australiacus, at up to 100mm.
The life cycles and habits of Victoria's Myobatrachids are more diverse than those of the hylids. Many are burrowers, some are swamp dwellers, and one lives only above the snow-line.
NOTE: When having trouble seeing the shape of a frog's pupil, shining a light at it for about a minute will cause the pupil to shrink and reveal its true shape.
Belly either:  mottled or flecked with dark pigments on white or light grey;  with little or nor markings;  orange or yellow often mottled with darker pigment; or  brown with large lighter spots.
