The main issue I see would be at cable joins, that's where stuff
always seems to go pear shaped.<br>

I hope they are in rural areas, they dug out the foundations of my
grandmother in laws house ;-><br>
You know one of the reasons the new power lines they are running are
all twisted together is because Cockatoos don't like to sit on them
and chew the wires (as they do for the current ones)<br>
<br>
Does anybody know where one could find what the physical in ground
layout of the NBN is? <br>
IE how does the cable/data get from one of the POP's to a customers
premises?<br>
