On the Australian continent several tribes of indigenous people played kicking and catching games with stuffed balls which have been generalised by historians as Marn Grook (Djab Wurrung for "game ball"). The earliest historical account is an anecdote from the 1878 book by Robert Brough-Smyth, The Aborigines of Victoria, in which a man called Richard Thomas is quoted as saying, in about 1841 in Victoria, Australia, that he had witnessed Aboriginal people playing the game: "Mr Thomas describes how the foremost player will drop kick a ball made from the skin of a possum and how other players leap into the air in order to catch it." Some historians have theorised that Marn Grook was one of the origins of Australian rules football.
