Filming sexual conquests very common at Oz navy training base

He filmed the incident on his mobile phone and at one point turned to the camera and gave the thumbs up gesture.

Calvert,24,has argued during his pre-sentence hearing that bragging about sexual exploits and capturing them on video was common at HMAS Cerberus,south of Melbourne,where he was based as a trainee at the time.

His barrister David Sexton said the culture was one of work hard,play hard and heavy drinking.

He said his client had joined the navy to make friends as he had been a loner growing up and was determined to fit into his new environment.

There was a culture of reporting,of bragging,of sexual exploits,that extended to revealing ones exploits by way of mobile phone footage, the Age quoted Sexton as telling the hearing at the Victorian County Court.

Sexton said the filming was not so much a frolic of his (Calverts) own,but an alcohol-fuelled product of the environment that he experienced.

He said the incident at the East Brunswick home was opportunistic rather than planned or premeditated.

Calvert,of Thomastown,had pleaded not guilty to one count of indecent assault and four counts of rape.

The jury found Calvert guilty of two counts of rape but not guilty on the other rape and indecent assault charges.
