1/6/11, 2/6/12 or 3/8/13 in Australia (The US has only 1-11 available, 
hence the not quite correct reference here)...

Have that problem here.  I run on channel 13 here, which is out the way, 
but there are other APs within range on channels 6 and 7.  That could be an 
issue when I get round to putting my AP up a pole.  Fortunately, in the 
long term, I can "reclaim" channel 13, by converting my internal LAN to 
802.11a.  That will leave me 2 clear channels - one low, one high, and make 
the internal network a smaller target for wardrivers (who would see all the 
open but firewalled stuff outside :) ).
