Yep, There's a reason why those area's are cheap.
""a smorgasbord" of reasons not to buy, and the Blacktown/Mt Druitt region is regularly held up as a symbol of society gone wrong. Ethnic tensions, high crime rates and aircraft noise are reasons to stay away from Bankstown, and Blacktown/Mt Druitt is no better."
"The two other noteworthy increases in crime across the State were a 59 per cent increase in robbery without a weapon in the Central West"
"# Sydney Local Government Area, and therefore Inner Sydney Statistical Subdivision, has high recorded crime rates because, compared with other regions, the resident population is small relative to the number of people in the area. In other words the area has a high user population which is not reflected in the denominator of the rate calculation. "

I'm not trying to put anyone who lives in the western subburbs down. It is just a well known fact that the crime rates are higher so you have to be a bit more careful. There is plenty of crime that happens in every suburb. Just some of the worse ones tend to happen out in the western area's.
And I'm not saying that just because someone lives north or in the eastern suburbs they should be less aware or not have alarms or insurance.
