Has an AFL game ever ended 96-30?
Exactly once. On June 12, 1954, Sydney beat St Kilda 96-30, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 96-30 in league history.
That makes 96-30 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 97-30 has happened never and 96-31 has happened never.
