Has an AFL game ever ended 71-32?
Exactly once. On July 6, 1907, Geelong beat Fitzroy 71-32, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 71-32 in league history.
That makes 71-32 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 72-32 has happened 1 times and 71-33 has happened never.
