I have Foxtel and have had it for years... how do I afford it you ask? Well, I have 3 box's - 1 is at my house, 1 is at my parents house and 1 is at my wifes parents house.
We then split the bill in thirds which results in us paying about $40 or so each/ month.
This works as long as everyone has either Cable OR Satellite connections - Foxtel have no way of ever know where the box physically is and as long as the bills are paid, they never will.
These days, there is a very good chance that a house that you rent or buy will have a connection from past occupants - if it does, find a mate that has foxtel, get an extra box "installed" into their house then after the tech has gone unscrew it and take it home with you... instant half price Foxtel!
I know about a dozen people that do this with satellite. Didn't think it would work with cable though ??
