Boxing kangaroo

The symbol is often displayed prominently by Australian spectators at sporting events, such as at cricket, tennis, basketball and football matches, and at the Commonwealth and Olympic Games.

[1] The idea of a boxing kangaroo originates from the animal's defensive behaviour, in which it will use its smaller forelegs (its arms) to hold an attacker in place while using the claws on its larger hind legs to try to kick, slash or disembowel them.

[2][3] In the late 19th century, outback travelling shows featured kangaroos wearing boxing gloves fighting against men.

Alan Bond (owner of the Australia II yacht) owned the image and licensed it for mass production.

The IOC ordered the flag to be taken down as they believed the symbol to be "too commercial" as it is a registered trademark (albeit of the Australian Olympic Committee, a non-profit organization).
