That would have been Peter Reid, who was living in "Graduate House".
He's still alive, living out Macedon way.

My father was a leading Melbourne orthodontist who stayed away from
Panorex shots for many years because he had a way of aligning the
lateral-oblique xrays to minimise distortion - but those can't show
undistorted front and side teeth inthe same shot. Despite the rather
high dosage required to take a Panorex (3 second exposure), he now
says that everybody should have one, just to see exactly what's
going on in every part of their mouth.

My first job as a computer programmer was in the Child Growth Unit of
the Uni of Melbourne, in 1981. We processed digitized tracings of a
library of xrays collected from 120 selected subjects every year to
their 21st, the unit having begun in 1952. Hate to think what their
xray dosage must have been - wrists, lateral and A-P skull xrays, and
some Panorex shots. My boss is still alive, I'm sure he'd remember
when the Panorex unit was acquired even though my father doesn't.
