Australian actor Margot Robbie has received two British Academy of Film and Television Arts (BAFTA) award nominations in the same category, as social media users decry the lack of diversity among the nominees.

Key points: Margot Robbie has been nominated twice for best supporting actress

Robbie will compete against herself in the best supporting actress category after receiving nods for her roles as Sharon Tate in Quentin Tarantino's Once Upon a Time … in Hollywood and fictional Fox News employee Kayla Pospisil in Bombshell.

Scarlett Johansson was also nominated twice but in two separate categories. She will compete against Robbie in the best supporting actress category for her role in Jojo Rabbit, and has also been nominated for a best actress BAFTA award for Marriage Story.

Laura Dern (Marriage Story) and Florence Pugh (Little Women) have also been nominated for best supporting actress.

Robbie's unusual feat of being nominated twice in the same category cannot be repeated when the Academy Awards nominations are announced next week.

The US Academy of Motion Picture Arts and Sciences prohibits an actor or actress being nominated more than once in the same category.

But that rule does not stop non-actors from being nominated twice in the same category, as Steven Soderbergh received best director nominations for Traffic and Erin Brockovich in 2001 before picking up the award for Traffic.

Robbie has previously been nominated three times at the BAFTAs but has failed to pick up an award.

She received a rising star award nomination in 2015 after her breakout role in Martin Scorsese's The Wolf of Wall Street, a best actress in a leading role nomination for I, Tonya in 2018 and another best actress in a supporting role nomination in 2019 for Mary Queen of Scots.

Robbie was nominated for a best actress Academy Award for I, Tonya in 2018.

The Queenslander shared a video to Instagram before the Golden Globes ceremony on Monday, pleading with her followers to donate to bushfire relief.

Lack of diversity decried

Robbie and Johansson's nominations sparked controversy on Twitter, with social media users frustrated at the lack of diversity in the categories recognising actors.

Under the #BAFTASsowhite hashtag, people expressed dismay that Jennifer Lopez, Awkwafina, Cynthia Erivo and Lupita Nyong'o were passed over, while Robbie and Johansson were nominated twice.

Awkwafina, who became first woman of Asian-American descent to win a best actress Golden Globe on Monday, did receive a rising star nomination.

BAFTA executives themselves expressed dismay at the lack of diversity reflected in the nominations, which put only white actors up for the major acting prizes and also have no women competing in the best director category.

"Being totally honest, we are disappointed, and that is not to take anything away from the people who have been nominated," British Academy chief executive Amanda Berry said.

The nominees in the majority of categories are selected in a vote by 6,500 BAFTA members around the world.

The Joker leads the nominations, with Todd Phillips's film in the running for 11 BAFTAs.

The Irishman and Once Upon a Time … in Hollywood each received 10 nominations.

The winners will be announced on February 2 at an event hosted by comedian Graham Norton, a past BAFTA winner for his TV chat show.
