Man dies after fall from bull at Qld rodeo

"He was riding the bull, came off and the bull landed on him," witness Melanie Jai wrote in a Facebook post.

Paramedics treated him at the scene, with revellers told the family fireworks would be delayed due to "a serious arena incident" in a post by the Warwick Show and Rodeo Society on Facebook.

The man was rushed to hospital in a critical condition after suffering "serious chest injuries", Queensland Ambulance Service said.

Police said the man later died of his injuries.

A report will be prepared for the coroner.
