Updating this old questions ... for th einfo of others.
ADSL speed will depend amongst other factor of how far away you are from your ADSL Exchange
In the case of Paul from Perth, he should look at
http://www.adsl2exchanges.com.au/providerexchanges.php?Location=WA
and
http://www.adsl2exchanges.com.au/heatmap-state.php?State=WA
Find your local Exchange and compare your speed with that of others
Good luck
