In another one at Sydney where the umpires seemed to ignore the rules was in 2019 against Essendon when Rampe climbed the goal post after the siren just a couple of seconds before the Essendon player took the kick.Swans getting the rub of the green after the final siren sure does occur a lot then.
Scores were 77 - 72 and the fifty would have put him on the goal line. Seems like lightning does strike twice.
