High-profile hurdler Michelle Jenneke arrived in Rio out of shape and needs to make athletics a higher priority if she wants to continue being funded and to make it at the world level, Australian head coach Craig Hilliard said in a sharp rebuke.

The dancing hurdler, who was one of the international faces of Coca-Cola, said after her elimination in the heats that athletics was only one priority in her life.

In a stinging review of performances, Hilliard said Jenneke was among a group of athletes who had under-performed in Rio.

"There are a lot of things that will come up in the review. I don't really want to mention a lot of stuff about athletes but she was certainly one of the athletes that underperformed here," Hilliard said.
