Wolf Creek star accused of sexual assault

Wolf Creek actor John Jarratt has been accused of sexually assaulting a woman in Sydney's east in the 1970s but he "emphatically" denies the claim.

"Police are investigating an allegation of a historic sexual assault on Sydney's eastern beaches," a NSW Police spokeswoman said in a statement on Saturday.

"The allegations were reported to police earlier this month and relate to a matter from the 1970s."

News Corp Australia reports the woman made a statement to Shoalhaven police about a week ago.

Jarratt's representative told AAP on Saturday that the 65-year-old "emphatically and completely denies the allegations of sexual assault".

"These allegations are completely unfounded and untrue," Ignite Elite Artists said in a statement.
