It looks as though it should be Cerambycidae sp (Longicorn) except for two small issues. The dark tufts on 2nd antennal segment and an apparent lack of antennal spines.
It measured approximately 3cm. Perhaps a little over.
Anyone know what it is?

It's possible my Longicorn might be Cnemoplites edulis (Newman) commonly known as the Mallee Witchetygrub - but then again! They both seem to have a similar dorsal stripe but antennal segments might not be quite right.
I might see if the Museum of Victoria can offer a suggestion. :-)
