Melbourne: The Australian military has been rocked by a sex scandal after a 23-year-old soldier was arrested over the alleged rape of a civilian woman at a military college.

The soldier has been arrested and charged with raping a 21-year-old woman at Canberra's Royal Military College, Duntroon on Friday.

The incident comes just weeks after the military handed down wide-ranging reviews of Defence culture, including how to handle sexual abuse and the treatment of women.

Police said the alleged victim contacted them to report that a man known to her had sexually assaulted her before fleeing, as reported.

Police later located a man in the grounds of Duntroon and charged him with two counts of sexual intercourse without consent.

A Defence spokesman confirmed that a member of the Australian military had been charged with alleged sexual offences.

"The Australian Defence Force Investigative Service is assisting the Australian Federal Police in their investigation," he said.

The charges come in the wake of the Australian Defence Force Academy so-called 'skype scandal' last year, in which an 18-year-old cadet alleged she had been filmed and broadcast without her knowledge during a consensual sexual encounter.
