This is not quite true. I got my Internet connection from Dodo in dec 2011 and it works pretty well for me. Dodo service is based on Telstra infrastructure in this area. Don't get distracted by ADSL1 v ADSL2 discussions too much. No provider will provider top ADSL2 speeds anyway.
Absolutely Useless in Seville Grove, its a suburb randomly placed between Armadale and Kelmscott and its directly between those to exchanges and stuck on ADSL 1 thats rimmed of the Armadale Exchange its So slow its not funny the only way to get decent Internet is to get Vivid Wireless and and put WIMAX Panels on a Tower in your back yard and then you get faster internet still crap for gaming, but yeah i got the best internet in Seville Grove due to my WIMAX panels on my house haha lol i used my neighbours internet and its sooooooooooooooo sloooooooooooooooow
