治安ok啦, everywhere is more or less the same. Rochedale is a popular residential area for Asians, so the property price is on the high side. It's close to Sunnybank which has become the new "China Town". There are a number of large, medium or small scale shopping malls/centres around this south east Brisbane area, such as Garden City, Sunnybank Hill Shopping Town, Hyperdome, etc. Ikea is just about 20 minutes away. Before moving to Brisbane for good, it's better to come to experience the life here first, rent your own car and stay in air B&B so that you can cook your own food (of course you can also eat out coz there are lots of Hong Kong style restaurants around).
