I wonder how many times he did that for the news camera. If his medal throwing is anything like his football throwing, I doubt they were able to do in in one take.
Probably one take - he's a pro. After his acting career in VN and starring in his own film documentary about what a hero he was storming about in the elephant grass shot with his own movie camera, he's had plenty of practice. Plus, he threw other people's medals - his own hang on his office walls today (proudly - according to the horse faced idiot).
