It was the underdogs who had the makings of the trophy, however, leading by two Wayne Huntley goals with only a handful of minutes remaining.
Between the 83rd and 86th minutes, however, Colin Shaw hit the target twice for the Bay, the second of the goals coming from a penalty which had to be retaken.
Bay dominated the two periods of extra time, yet it was Suburbs who came closest to gaining the upper hand, hitting the woodwork on two occasions.
The old rule of counting corners to decide the outcome of a tie had been scrapped and the idea of a penalty shootout had not yet been introduced, so the match headed to a replay.
Goals in the match came from Clive Campbell, Ian Ormond and Colin Shaw for the Bay and Bruce Baker and Barry Humphreys for Suburbs.
