Has an AFL game ever ended 57-57?
Exactly once. On April 20, 1996, Footscray and Hawthorn drew 57-57, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 57-57 in league history.
That makes 57-57 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 58-57 has happened 4 times and 57-58 has happened never.
