A new TV ad to raise awareness about organ donation in Australia has raised a few eyebrows at church groups.

But the creator of the Monty Python-esque advert is standing by his crucifixion theme.

The ad calls for more organ donation registration in Australia by using religion as a way of comically asking for donors.

According to Christian belief, Jesus gave his life to save ours and so writer and director Richard Bullock has played on that idea.

In the short film, two guards ask Jesus if he would register to donate organs, who gives his consent.
