The perimeter and parapet signage installed by the Ci Group and the MCG and Marvel (Etihad) stadiums was the first signage of its kind permanently installed at an Australian stadium. The perimeter signage is particularly newsworthy. For unlike perimeter LED that subsequently appeared at other grounds, it was manufactured specifically with Australian Rules football in mind. Head and body collisions were expected with the field of play so close. So the Ci Group ensured the LED hoods and substrate were made with a special rubberised material that had some give.
