I could name more programmes than you've listed there but I'm not just talking sitcoms, just in general. Most of the stuff I see over here that isn't paid for (FOXTEL) is either a rerun of a British documentary (24 hours in A&E, Ross Kemp, Louis Theroux), a British drama that's been aired over here, a version of a British reality TV programme (First Dates, Hells Kitchen, Master Chef) or even some naff old programmes like Midsummer Murders.
I watched 800 Words the other day and it was horrific.
One programme that is decent is The Block, loved it.
