For ***** sake, get off BigPond ... you are only contributing to Tel$tra's profits with little benefit to you.
Every other ISP will be better value for money.
From you post you state that you're on ADSL2, so here's a rundown of the various speeds.
Even though ADSL1 is capable of 8Mbps download, Tel$tra will usually cap at 1.5Mbps, sometimes at 3Mpbs, and rarely at 8Mpbs.
ADSL2 is capable of 12Mbps but the actual speed is anything from 1.5Mbps, depending on line condition, distance from the exchange, etc.
ADSL2+ is capable of 24Mbps, but with the same caveats as ADSL2.
If there is shitty copper and lot's of it between you and the exchange then there is basically nothing you can do.
Use DA's link and run it a few times to confirm. If it is between 1.5 and 12Mpbs then technically you are on ADSL2.
If you know what exchange you're on then it's easy to work out what speed to expect ... refer to the graph here
http://www.internode.on.net/residential ... rformance/Depending on where you are located, even changing ISPs may not get you better speeds if you are utilising Tel$tra's wholesale infrastructure (end to end equipment and the copper in between) ... my ISP is Internode but it's on Tel$tra's inftrastructure, and I can only reliably get 1.5Mbps on that service. Tel$tra are refusing to let Internode into their exchange and DSLAMs in my area which would enable me to get near full ADSL2+ speeds, but hey, that's wholesale telco gouging for you!
It's all quite simple really!
