Has an AFL game ever ended 61-48?
Exactly once. On April 24, 1954, Sydney beat Essendon 61-48, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 61-48 in league history.
That makes 61-48 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 62-48 has happened 4 times and 61-49 has happened 4 times.
