Australia / Poles in Australia - money for start, chances for a job, costs of living (Brisbane, Bunbury) [50]

Hi All,
My husband and I are in process of sorting our visa and relocating to Bunbury area.
Are there any areas which we should avoid looking for the flat rental?
Also, do you know if there is a webpage which will give me any idea of costs of living? Real estate web sites quotes flats from 300 pw but I can't find any info on the council Tax (city Tax) rates, electricity, water etc.

Thanks for any feedback and I hope to meet you all for a drink later in the year (fingers crossed!).

Maria & Glen
