Its in the City of Cockburn, the actual suburb is either Success, Yangebup or South Lake (it's sorta in the corner of the boundaries of all 3).
The suburb is Cockburn Central, in the City of Cockburn, used to be part of Jandakot back in the day but they eventually created a new suburb when the freeway went through
(They don't like suburbs being split by the freeway)
Either way Cockburn is a hilarious name and it never gets old, I work for a transport company and I'm always trying to find ways of making or eastern state staff have to say it
Anyway I drove past it early this morning and there are lots of internal lights on in the building and its really starting to look the goods, shame its for Freo and not West Coast
