Question regarding attribute: credit only

Depends on what sort of news program you are talking about. I don't necessarily mean the evening news for example. Breakfast television, specialised news programs and political series here often list reporters - not usually during end credits (although it does happen for programs such as Landline, Four Corners, Foreign Correspondent) - but often at the beginning or end of a segment.

Perhaps worth considering whether it is a cast credit. I guess a reporter who doesn't appear on screen or as a voice could also be Additional Crew.

That sounds to me more like a contributing writer or researcher, if you're talking about someone who did background reporting on a story; I agree that's probably Additional Crew.

But I'm not.
