Yes, looks a good match for L. exarans on iNaturalist, but I notice that L. exarans is included in the Species Inquienda for the subfamily Hadeninae on AFD and the ALA.
Glenn, ALA and AFD list this species in a Specis Inquierenda, see here: https://biocache.ala.org.au/occurrences/e42c0d52-e1b8-4c5e-b1d8-b9ab43ec1e0d iNaturalist accepts it as a species in their listing online.
