"and the question is could it have been avoided and if so how.."

Easy answer: Stop the boats and we won't need to fill up detention centres.

Whose fault is it:

* The people smugglers who made promises to these people when our government told them the rules.

* The rioters!! - These people are "escaping persecution" so I am astounded that these people would resort to any form of violence when it is exactly what they are trying to escape.

* The Labor Government/greens - Clearly they allowed violent people to enter our shores.

We should just count ourselves lucky that the men are separated from the women. Otherwise, mothers and children may have died as a result of this riot.

The government knows that "boat people/queue jumpers" are predominantly Males and i would suggest the government are aware that they resort to violence.
