Not quite! Apparently there's the find of a 1973 144 and most of a 1974 145 being discussed on FB, over near Bendigo somewhere.
73 144s are becoming exceptionally rare now. YMMV, but I believe they're important to preserve, as they had elements of 140s and 240s, but were truly closer to 140s; 74 models were closer to the 240.
