As in VK/ZL, along with a separate earth on a 6ft copper spike.  As I gaze 
out my window, I see a pole (the pig is further down the street) with 
three wires on top carrying 11kV (yes, really!)[*] and four wires a bit 
further down carrying the 415v + neutral; the household drops take a phase 
in turn plus the neutral.

[*]

Ah yes, the 11kV...  A common Australian bird is the cockatoo: yellow of 
crest, sharp of beak, raucous of squawk, and wide of wing.  So, picture 
two of them on adjacent 11kV phases, arguing away as they are wont to, 
whilst fluttering their wings.  Their wings touch...  Bang!  Result: two 
very dead cockies on the ground; they wouldn't've felt a thing.
