Has an AFL game ever ended 134-30?
Exactly once. On June 30, 1984, Hawthorn beat St Kilda 134-30, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 134-30 in league history.
That makes 134-30 the 3884th most common final score out of 6,649 that have ever occurred in AFL. One point away, 135-30 has happened never and 134-31 has happened never.
