when does cars 4 come out australia

Short answer: there isn’t an official Cars 4 release date in Australia—because there isn’t an official Cars 4, full stop. Disney/Pixar haven’t announced a new film; the last big-screen outing was Cars 3 in 2017. If you’re feeling Lightning withdrawal, there’s the Cars on the Road series, but that’s streaming telly, not popcorn cinema. Should a sequel get the green light, expect a standard Aussie rollout (cinemas first, streaming later), but for now it’s all tumbleweeds and speculation.
