According to director Justin Kurzel, Texan actor Caleb Landry Jones worked on his Australian accent while in quarantine after arriving in the country, by watching re-runs of 1990s episodes of Hey Hey It's Saturday (1971), Les voisins (1985) and Summer Bay (1988).

Early in the film when Martin and his mother browse at the Surfboard shop a passenger train is visible passing in the background. There are no passenger trains in Tasmania unlike in Geelong, VIC where the movie was shot.

End credits read "On April 28th 1996, thirty-five people were killed and another twenty-three wounded in Port Arthur, Tasmania. The lone gunman was sentenced to thirty-five life sentences. The events of that day resulted in an overhaul of Australia's gun laws and the introduction of a National Firearms Agreement. The reforms were agreed to in twelve days. Over 640,000 firearms were bought back by the government and destroyed. No State or Territory has been fully compliant with the National Firearms Agreement. There are now more firearms owned in Australia than in 1996."
