There are plenty of Aussies living in these areas with no problems, including single women. Who dont have problems. I dont live in the area anymore but am still very familiar with it as i know plenty of people there and am a regular visitor.
Evand, not sure how long ago you went to school but assume the area is much different than it was back then. My parents grew up in Granville/Guildford but none of their families live there anymore. for me, it's not about race but culture. Being yelled at by Lebanese teens circling me to ask why "a blondie" lives around here. Being pushed out of the checkout queue by a Muslim man at Kmart Merrylands because his wife should be served before me. Being propositioned by a group of charming Lebanese boys in a rather derogatory fashion while playing golf at Auburn.
if you're a fella on your own then it's no big deal to live around those parts. But would you want your teenage daughters there, or your wife? I lived in Guildford in my mid 20s and while I told myself it wasn't that bad, it wasn't nice at all. If I worked late, I'd get a cab from the city to drive me to my car at Guildford station, otherwise I'd have the locals escorting me to my car.
