Pet play or what?
Apparently the local Mayor can see nothing sexual in them, obviously not a fan of the Plaza then!
One local said they made a great bottle opener, points for where you'd stick the bottle.
Forbes, is a Conservative country town in rural New South Wales, mostly farming.
Back end - bottle opener :o
Taken at face value, my thought is that the mayor is either completely naive and socially out of touch in a big way, or they are completely lying out their ass and someone should doan investigation into their home night time activities.
Wikipedia has some background on the husband and wife artists, and a few other renderings of 'Dogboy' and 'Rabbitgirl.' (Maybe that's there alter egos?)

Nice work, I like that display. Maybe the local youth likes it too, as a place for drinking a few beer at the bottle opener... ;)
Otherwise I agree with Abbacor. ;) :D
