Eucalyptus Longhorned Borer from Australia

Unidentified bug
Hi. Attached is a photo of a bug found in Melbourne, Australia. I have looked all over the web but can’t find anything. Have you any idea what it is? Thank you!

Hi Corey,
Sorry for the delay. We are just returning to old emails that we never had a chance to answer. This is a Eucalyptus Longhorned Borer Beetle, Phoracantha semipunctata. This beetle has been introduced to Southern California where it is a major cause of eucalyptus damage. The larvae are the borers that feed on wood.
