Canberra has already been done using this method - I've currently got  
JOSM set to only show boundaries, all apart from author=ABS2006 greyed  
out, and certain other ways greyed out (highways, railways,  
coastlines, state/country borders). I've also been deleting relations  
once there are no longer any ways in them.

I haven't looked at all the state borders yet, but some of them at  
least are based on ABS data - prior to the ABS import, was there other  
data for state borders that can be undeleted, or will we need to add  
these in again?
