I found an article stating that the Qantas Lancastrians, which don't appear in any old Qantas timetable I have seen, were employed on RAAF charters for the Australian occupation forces in Japan, starting in late 1947 which seems shortly after they were bought from BOAC. They had supplementary military roundels which were a requirement of the occupation area, which probably precluded them from being rotated with any mainstream scheduled operation. I suspect they had a bit more than the 9 sideways-facing seats as well.
