Later this year (Saturday October 5th) at Adelaide Oval. Norwood & Port played in the first ever premiership deciding final.
Tied for wins at the end of the season they decided to play a one off game for the premiership .... Norwood won 7 goals to 5.
It would be another 5 years (1894) before another final was played before they become a regular way to decide the premiership in 1898.
Great they are meeting up again at the same oval, some 125 years later, in another big final.
