It does appear to be a good match for Syllitus recta - but this would be a large disjunction from the next nearest recorded location, a close up of the head and antennae may enable are more definitive identification
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.
