The show McLeod's Daughters killed off Claire (Lisa Chappell--who should be recognizable for her roles in HTLJ), one of the two leads, and I believe the show went on for at least two more seasons-- ok I just checked, it's up to season 7 and I'm trying to see if the other lead is still on the show. Unfortunately WE stopped playing it after the third season when they killed off Claire. It was an Australian or NZ show. From what I can tell, the other lead has also left the show, plus the male lead that she was coupled up with, but who knows.

Of course of the two sisters, Claire was my favorite.
