I'm also noticing the shopping centre along Warrigal Rd (where the old Bi-Lo used to be) is slowly becoming the Korean hub. It's full of Korean restaurants and a Korean supermarket. I can see that part of Eight Mile Plains / Runcorn becoming like the Strathfield of Brisbane. This is actually the main reason why I started taking Runcorn more seriously.
UPDATE: Hum this is interesting, I just did some research and my hunch was correct! Here are the top 7 suburbs for Koreans as of 2013 (data might be old but can't be too far off):
Runcorn (4.2%)
Stretton (2.4%)
Macgregor (2.3%)
Calamvale (2.2%)
Sunnybank Hills (2.2%)
Robertson (2.0%)
Sunnybank (1.7%)
You cant go wrong on the EMP side. The other side has seen dramatic demographic changes in the last 8 years and it's not from Asians. This is where I would tread carefully knowing what has happened to values interstate.
