Our initial thought is this must be a Horse Fly (called March Flies in Australia) from the family Tabanidae, but there are no similar looking images on the Brisbane Insects site. The white edge on the compound eye is a trait found in several Bee Flies on the Brisbane Insect site that share that trait. We are going to request assistance from our readership with this identification.
