Note: If two or more players tie for first in the Australian Open tournament, one is awarded the title Australian Open Chess Champion on countback. For 1989 Wohl, and for 1991 Oll, are included alone on the perpetual trophy but information is sought about whether and how the tie was broken for those years.
