NSW private conversation

Does a private conversation for the purposes of the listening devices act, need to be two people ? or could it be one person?

For example, a tradesman working by himself in a private building, hits his finger with a hammer and he starts swearing and screaming, but unknown to the tradesman another person starts taping the incident and sends it to some mates for a laugh.

Would the above incident be a private conversation and not be able to be recorded by the listening device act or similar

Thanks Rod


That’s was my thinking as well, but gets tricky as the privacy act in my rough opinion does not seem to cover audio when being filmed
