Trying to locate the name of a couple of short thriller/horror films (possibly Australian) about a young couple terrorised by something unseen in the darkness outside their house. You only ever saw patch of light from the inside of their room. The man eventually goes outside and something nasty happens! Shown around 1988/89 on Channel 4 in the UK!
Around the same time, same channel an Australian period horror short about a woman on her own in an isolated house and under threat. She calls for help on the phone and receives reassurance that help is on the way. Eventually its revealed the phone is disconnected!
