My understanding is DOCSIS 3.1 can give a per segment bandwidth of 10Gbps down / 1Gbps up, although I would expect if a certain amount of bandwidth is used by Foxtel it may be lower in practice. It would seem NBNCo have a plan to deploy DOCSIS 3.1 across their HFC networks ( http://www.theregister.co.uk/2015/03/12/nbn_co_adopts_10gbps_docsis_31_from_2017/ )
That bandwidth is indeed shared between all users on a given cable segment - the smaller you make each segment, the less oversubscription. What will be interesting is seeing how NBNCo deal with the trade-offs between cost of deploying more HFC nodes to make each segment smaller as bandwidth demands increase.
