Who else provides cable apart from Telstra and Optus? My place can only get Optus cable, so it would have to be an ISP using optus cable.
with regards to optus cable See if somone else will contract you on to said cable ? the state of optus cable is a sight for sore eyes compared to telstras HFC with that said you almost never get 24mbps on ADSL2 so if the cable performs up to Spec then i would say Yes yes it will and go for it , i would argue for them to include 100mbps for free other wise just pay the $20 extra :) hopfully it will be of use if its not demand a Refund
I'll be happy if the 30mbps cable even gives me close to a steady 20mbps. The adsl2 barely touches 11mbps. NBN isn't coming to this place until early 2018. :(
The upload speed is the most concerning. 2mbps even on cable..
