Why this violence in australia?

I've also heard some info. about this kind of attack from the tele.In fact,most of the cases,it's not the racism,i think.Maybe,those were attacked have some charateristics (holding fashionable phone or other devices,or wearing luxurious clothes)Anyway,Indian in Australia should be careful,and peoples from other lands should be as well.As for the racism issue,i do not know,why this could be exist in a so-called democratic country.Both India and Australia governmnets should take this and cope with it seriously in case of someothing unexpected!

first of all I want to know whether they are attacking only on Indians or they are attacking on all brown skin people, because as I know Indian and pakistan look similar in skin so if they are attacking only Indians then there must be any logic I think they can not tollerate by seeing the improvement of Indians at there country

You know,this is the million dollar question....No body takes the responsibility..But this damm thing is going on with the Indians.. The police is investigating,it may or may not be a racial violence, and Australian PM has nothing to say before the reports come... This are tragic incidents..And many of the students are visting their land on a schloraship program.I don't understand why these people feel insecure with the Asians.
