Updated – Now identified!
Thanks to an amazingly fast turn around by the Queensland Museum the mystery creature has been identified as a fly belonging to the family Nemestrinidae and the genus Atriadops more commonly known as ‘Tangle-veined Flies’.
This particular fly is a female of the species so the scary looking protrusion is in fact a ovipositor used in egg laying (note that wasps stingers are also ovipositors although highly modified ones).
They are of no threat to humans but their larvae are parasitic on other insects such as grasshoppers and possibly katydids or cockroaches.
This information was provided by Dr Christine Lambkin the Biodiversity Curator of Entomology at the Queensland Museum.

Living in Australia you get used to see all sorts of odd and interesting critters, many of which can possibly kill you (not entirely true but it is fun to keep tourists on their toes about it). Whilst walking around the Brisbane Botanical Gardens at Mt Coot-tha I found this impressive and just a little scary critter.
I’ve not seen anything quite like it before. It was quite large being roughly the size of my thumb in terms of length and width. I’m not entirely sure if the protrusion from the abdomen is actually a stinger but I wasn’t game enough to get close enough to find out.
The wings were moth like whilst the face resembles something from the fly family, overall it’s a very strange critter indeed. I’ve submitted it to the Queensland Museum‘s inquiry systems so hopefully they might be able to shed some light on it.
Meanwhile does anyone else have any idea what this strange critter could be? Another shot below shows the profile just before it took off.
