Australian women's basketball player Liz Cambage is protesting the lack of racial diversity in Olympic photoshoots of the nation's athletes and has suggested she might boycott the Tokyo Games if the situation does not change.

Cambage, a two-time Olympian, criticized pictures of Australian Olympic and Paralympic athletes, taken at sponsors' photoshoots, on her Instagram account.

"If I’ve said it once I’ve said it a million times. HOW AM I MEANT TO REPRESENT A COUNTRY THAT DOESNT EVEN REPRESENT ME #whitewashedaustralia,” Cambage, who was born to a Nigerian father, captioned a photo for underwear sponsor Jockey.
