Paul,
Over here in NZ, the Emergency Number is
111, in Australia, it's 000, I think?.
It all relates, to how the old Dial phone
was set out, as in least time required to dial the required numbers.
The NZ system, blew this all out of the water, our old Dial system, went 0,1,2,3,4,5,6,7,8,9, in a clockwise direction.
Thank God, for DTMF keypads!. [Linked Image]
