Few years back, Aust domestic carries had 3 classes on each planes they flew.
I remember up to the early 1990s, 1993/1994, Aust planes still had dom first class.
Not that I flew them, but was told, never had the chance to ask the person to she me her Aust domestic First Class (at that time) BP though.
Have tried to see them on google images, but none comes up.
Maybe one of our colleagues on here still has photos stored, maybe even the originals.
