Longicorn beetle?

Description:

A longicorn beetle approximately 45mm long with antennae spread about the same. Very dark bronze on top with slightly hirsute, red-brown femurs and antennae segments.

Habitat:

Suburban fringe to dry eucalyptus forest. This one appeared on glass window at night.

Notes:

Yet to search for ID on this... These are usually called longhorn beetles in other countries (which makes far more sense to me). This one stayed on the glass for a long time and seemed to clean its antennae by wiping them down with various feet. In pic #2 you can see from underneath that both antennae are under a foot.
