I have it on authority from Dr Adam Slipinski (co-author of the CSIRO book series "Australian longhorn beetles (Coleoptera: Cerambycidae)" that this is an undescribed species, meaning it hasn't been formally named and diagnosed. It is a member of the subfamily Cerambycinae.
I have to add that this beetle may have originated in central or southern Qld and been transported from there within the timber as a borer. I don't have the original source location of the timber.
