I have 14 pages of my .au site in the worldwide index. I now have only one left in the Australian index (it also has a strange ending ...default?Sess=1 which is something I don't understand either).
I have been told by AV Aus that when spidered after submitting to altavista.com, a .au site will be identified as Australian content and end up in the Australian index. (You can't submit direct to Australia at present, though I'm told you will be able to soon.) But it's just not happening for me and I can't fathom it. I desperately want to get back to a decent ranking here. I have to say the AV Aus staff have been very responsive to my emails, but I'm still not getting anywhere and worry about becoming a pest.
