When was the alternative to the Easter Bilby first mentioned?
Easter Bilby: The Easter Bilby is an Australian alternative to the Easter Bunny. Easter Bunny: The Easter Bunny (also called the Easter Rabbit or Easter Hare) is a folkloric figure and symbol of Easter, depicted as a rabbit bringing Easter eggs. Originating among German Lutherans, the "Easter Hare" originally played the role of a judge, evaluating whether children were good or disobedient in behaviour at the start of the season of Eastertide. Easter Bunny:  The custom was first mentioned in Georg Franck von Franckenau's "De ovis paschalibus" ('About Easter Eggs') in 1682, referring to a German tradition of an Easter Hare bringing Easter eggs for the children.
