This weekend, the AFL will stage its annual Sir Doug Nicholls Round, named in honour of the Yorta Yorta man who remains one of the game's most legendary athletes.
The round celebrates Indigenous players and culture, yet there won't be an Aboriginal flag taking pride of place in the centre of the oval, nor will there be any emblazoned on the players' specially designed jerseys.
Because the league hasn't paid a copyright fee.

The man behind the Aboriginal flag.
The Aboriginal flag was designed in 1971 by Harold Thomas, an artist and Luritja man from the Northern Territory.
It's an image steeped in symbolism: black on the top to represent First Nations people; red on the bottom, to represent the earth; and a yellow circle for the sun, the giver of life.
The design was first flown for National Aboriginal Day in Adelaide in 1971. But it gained national visibility the following year when it was used at the Aboriginal Tent Embassy, a permanent Indigenous rights protest site established outside Parliament House in Canberra.
More than two decades later, on July 14, 1995, the Governor-General issued a proclamation that declared the design to be the official flag of the Aboriginal people of Australia.
Following the declaration, several artists came forward claiming to be responsible for the design. But in 1997, the Federal Court of Australia ruled that Harold Thomas was its true author and copyright owner.
As Isabella Alexander, Professor of Law at the University of Technology Sydney, explained via The Conversation, "Under Australian law, his copyright will last for 70 years after his death, and can be claimed by his heirs or anyone else to whom he might choose to assign it. Thomas can assert his rights against anyone making any copy of the flag, even if they are not selling it or using it commercially – this could even include bringing an action against someone with a tattoo of the flag."
