It’s Margot Robbie versus Chris Hemworth!
The two Australian actors appeared on Wednesday's episode of The Ellen DeGeneres Show, going head-to-head to see which was the best Aussie.
"Since Margot Robbie and Chris Hemsworth are both Australian, we’re gonna play a trivia game,” DeGeneres told the audience, calling the game "Ellen's Australian Boxers."
Dressed in kangaroo onesies with oversized boxing gloves, Robbie and Hemsworth were asked a handful of Australia-based trivia questions, including naming an Olivia Newton John song, Nicole Kidman's birthplace (which is, surprisingly, not in Australia) and even their best Crocodile Dundee impression.
While the I, Tonya star was ahead of the Thor actor, DeGeneres almost stumped her when she asked her to choose between Chris or his brother, Liam Hemsworth. Robbie ultimately chose Liam because she's "worked with Liam twice. Liam gets my vote."
Watch the hilarious bit below.
Both stars also made an appearance at the 2018 Golden Globes on Sunday. Hemsworth took the stage as a presenter, while Robbie was nominated for her outstanding role as Tonya Harding.
ET chatted with the blonde beauty at the end of November, where she revealed how difficult it was to play a real-life person.
