Its either Telstra or Optus.
The same cable also can supply Foxtel or Optus movies.
Unfortunately only these 2 companies can supply as they control the cable network.
Some areas have a choice of either Telstra or Optus, my street only has Telstra.
In my previouse reply I stated that I had a 512 k connection, that was incorrect.
My connection is 8mbps/128kbps unlimited download, and because I roll all my Telstra bills into one bill I pay $49 per month, I have had cable now for about 6 years and it has got cheaper in that time, I used to pay over $70 a month when I first hooked up with cable.
I can usually download far faster than any ADSL or ADSL2, so as I stated earlier, don't be in a big hurry to buy those 1500kbps plans because most of the time the servers just can't deliver those speeds. :*
Cable is definately the way to go if you can get it. :(
