Chris Lambkin on iNat has suggested this ID: Ectinorhynchus pyrrhotelus (a member of Stiletto Flies Family Therevidae) with the comment: currently but actually undescribed species
Chris' bio says: Taxonomist of Bombyliidae (Beeflies) and Therevidae (Stiletto Flies) especially Australian. Complete phylogenetic analyses of morphological and molecular data, especially of Diptera (True Flies) to estimate evolutionary relationships upon which to base classifications.
