I think this lauxaniid is probably Poecilohetaerus pinnatus, based on the white stripes on the head and thorax, colouration and white fore-tarsi. iNaturalist has 2 images of this species. Schneider (2007, Revision of the Australasian genus Poecilohetaerus.... Aust J Ent 30(2) 143-168) recognises 14 species in the genus. From the image it is not possible to see all characters but pinnatus fits.
