A lot of American shows and on the extra freeview channels there is a lot of old reruns of UK shows, dads, army, the Bill, keeping up appearances, you name it and if its old enough you will find it.
SBS has some good documentaries and ABC is similar to the BBC. Some of the other channels it can be hard to tell when one program ends and another starts, I have watched a program and suddenly realised it had morphed into something else during an add break. If you have a recorder then you have to set it to start recording 15 min early and over run by at least 15 min, I do not know for the life of me how they do it, but every days the TV schedules are way out.
I believe you can get satellite TV for around $100 a month but not heard many good reports about that either. So all in all, pretty rubbish really, but if you search you can find some decent programs on some channels.
