PRETORIA - A documentary revealing unseen footage of murder accused Oscar Pistorius re-enacting the night he shot and killed Reeva Steenkamp, has been broadcast in Australia despite concerns his legal team may attempt to halt it going to air.

Channel 7 obtained the footage from American forensic animation company The Evidence Room.

The footage shows an awkwardly mobile Pistorius walking on his stumps pretending to hold a firearm, before putting on his prosthetic legs in a mere 25 seconds.

The athlete's sister plays the role of Steenkamp, as she is picked up from a bathroom floor and carried down a flight of stairs.

Pistorius remains calm throughput the re-enactment, in stark contrast to his emotional episodes in court at the mere mention of this sequence of events.

The documentary includes interviews with Steenkamp's friends and family, who say the couple fought a lot in the weeks before the shooting.

Pistorius family spokesperson Anneliese Burgess said a statement will be released later today.
