I don't know so much about Sunnybank other than the brief time I've spent there when doing some suburb DD on the ground.
But... If the Chinese are taking interest in house stock there, I'd advise taking a look at school zonings. We all know that the Chinese discerning buyers value good school catchment zones quite highly, so if Sunnybank is sitting in catchment for good schools, there's your reason why the Chinese interest and possibly why the example provided, achieved such a ludicrous price.
Think of it like Sydney's Epping. A 'nothing special' suburb on its own (another example: Sydney's Hurstville) but the school catchments attract Chinese buyers like ants to a picnic. If you can get access to Brisbane's top ten ranked best performing HSC/year 12-results public schools; you can be sure the suburbs those schools are in will be Chinese hot-spots.
