The hilarious footage shows the young Paige Ormiston sitting on the ride with her uncle Mitch sat next to her.
Her terror is clear to see as she screams when the ride drops from the sky.
But as the coaster powers back up the hill, an ibis bird appears out of nowhere and hits Paige square in the face.
Mitch turns to his niece in shock as she can be seen mouthing: “Holy f***.
“Oh my God, what the f***.”
The pair look at each other again and laugh before the ride comes to an end.
Paige’s mum Nicole posted footage of the moment to Facebook, after it happened on Movie World’s HyperCoaster in Gold Coast, Australia.
She wrote: “Paige just got hit by an ibis while riding front seat on the DC rival hypercoaster with uncle Mitch.
“She had feathers on her and a beak scratch on her right shoulder.
“She’s completely shocked, a little bruised but okay.
“Not sure about the bird?”
More than 235,000 people have seen the clip since it was posted on July 28.
“That’s so scary,” one wrote.
Another commented: “I can’t stop laughing.”
And a third added: “Funniest thing I’ve ever seen.”
