Would this be the same NBN HFC that can't provide static addresses and IPv6 from any* provider? Our shiny new HFC NBN connection gets 70%^ of the bandwidth we are paying for and it only costs slightly more than the naked DSL that was providing double the download speed and 4 times the upload speed.
*Aussie Broadband claims to be planning IPv6 and may do IPv4 static today. Telecube is working on IPv6 too. Internode will migrate IPv6 ADSL plans to HFC where they don't support it.
^70% on IPv4 traffic. 0% of IPv6.
