Victoria has the most violent prisons in 
	Australia, with a prison officer assaulted every three days, figures 
	obtained by the ABC have revealed.
	
	The Department of Justice data also showed 
	inmate fights were a daily occurrence.
	
	Commonwealth Public Sector Union secretary 
	Karen Batt said the attacks were vicious.
	
	"We have had assaults where prisoners have put 
	billiard balls in a sock and hit prison officers in the head," Ms Batt said.
	
	"We've had fractured eye sockets, we've had 
	people hit over the back of the head with a billiard cue."
	
	One prison officer detailed some of the 
	attacks, but asked the ABC not to identify him for fear of reprisals from 
	Corrections Victoria.
	
	"I've seen prisoners attack officers with 
	chairs and tree branches," he said.
	
	"It's only a matter of time before a prison 
	officer dies in a prison. We've been extremely lucky up until now."
