I can't say if Jno. Hy. Andrew & Company was making tubes in Australia but the firm seems to be a conglomerate that moved into a steel making center and absorbed existing firms, possibly made some modification to the existing infrastructure then injected their Toledo steel recipe, which looks to have arrived on the scene in 1906 and may have been time varying. In the U.S. of A. they were under the name Newman-Andrew Company:
