The Australasian Robins (Petroicidae) include 46 species, endemic to Australasia: New Guinea, Australia, New Zealand and numerous Pacific Islands as far east as Samoa. Within the family the species are known not only as robins but as scrub-robins and flycatchers. They are, however, only distantly related to the Old World Flycatchers.

Most species have a stocky build with a large, rounded head, a short, straight bill, and rounded wingtips. They occupy a wide range of wooded habitats, from subalpine to tropical rainforest, and mangrove swamps to semi-arid scrubland. All are primarily insectivorous, although a few supplement their diet with seeds. Hunting is mostly by perch and pounce, a favoured tactic being to cling sideways onto a treetrunk and scan the ground below without moving.
