An ABC/Four Corners report has found that New South Wales detectives were refused permission to travel to South Australia to obtain a statement from the complainant at the heart of a historical rape allegation against former attorney-general Christian Porter.

Despite a recommendation from the Child Abuse and Sex Crimes squad, NSW  Deputy Commissioner David Hudson refused the travel citing COVID-19 restrictions. 

Christian Porter has strenuously denied the allegation and has lodged defamation proceedings against the ABC for their reporting on the story.
