1973 SANFL season

The 1973 South Australian National Football League season was the 94th season of the top-level Australian rules football competition in South Australia.

After a 39 year absence of any silverware, Glenelg were the dominant team of the season, recording only a single loss to North Adelaide in Round 7. They stormed home to a narrow grand final victory against the same club after Graham Cornes kicked a famous goal late in the game.

Unfortunately, the season was more famous for the tragic disappearance of two children from a game between Norwood and North Adelaide.
