Australian Film (I think)

i watched this film on BBC2 In the late 90’s.. It was an Australian film, 2 sisters or maybe friends. I think one injured the other somehow rendering her friend disabled. She felt guilty about injuring her and took it upon herself to look after her injured friend. There was a standout scene where the disabled friend lifts her top up, exposing her breasts and asking ‘Don’t you liiiike me?’

I think the disabled one ends up pushing her friend off a cliff in a revenge attack at the end. I’m 32 now and we must have been about 15 or 16 when we watched it. If anybody can help my mate will think I’m a magician. Cheers.

Got something to say?
