A picture of a soldier being humiliated in a prank by other soldiers has been branded as "gross" and "revolting" by one of the country's most respected art critics.
On the Australian War Memorial's website, "The People's Sit-up Challenge" depicts a blind-folded soldier on his back on the ground with another soldier squatting over him, naked apart from his boots.
The other soldiers laugh as the man on the ground appears about to make contact with the soldier above's bottom.
