The 1970s Adelaide ABC bunker at Collinswood is way too big – and way too empty. There are far too many deserted corners for staff to plot in.

Things are finally reaching a peak. There’s a full staff meeting set for Friday where grievances about local ABC boss Tom O’Byrne will be raised. And there are rumours that a very interesting letter went his way yesterday, a letter that might rock his world and leave ABC Human Resources a very different place.
