There are 7 species of Australasian treecreeper in the passerine bird family Climacteridae. They are medium-small, mostly brown-coloured birds with patterning on their underparts and all are endemic to Australia-New Guinea.

As their name implies, treecreepers forage for insects and other small creatures living on and under the bark of trees, mostly eucalypts, though several species also hunt on the ground, through leaf-litter, and on fallen timber.
