When you live in the Australian bush, you get used to seeing snakes around the place, after a while you take them in your stride.

But you never get used to finding them actually in the house.

Liz Powell's family has a long-standing relationship with a very big carpet snake, or diamond python, at their farmhouse near Walgett in north west NSW.

He's been a fixture of the household for the past 17 years.

And Hector has been a useful member of the family, keeping the mice under control, warning off venomous snakes from the garden and feeding off frogs around the house.

But Liz says that Hector the carpet snake has pushed his luck with his latest adventures, and he's been banished from the garden.

"I was in the shower and I was annoyed because the pressure pump kept cutting out; I threw my hands in the air and looked up.

"And there was Hector, hanging from the shower rose, about 15 centimetres from my head."

So Hector was firmly grasped and put back outside.

Several days later when Liz returned from a trip to Sydney, she says she was in the toilet and became convinced there was someone in the room with her.

"And I looked up and here he is, hanging from the window sill.

"He's been banished to the woolshed now."

Liz says she's still a bit jumpy, after her encounters with Hector in rooms where she would expect a little more privacy."I'm being very careful now.

"I'm careful when I put my hands in the washing machine, he's been in there in the past as well.

"Bill went to pull him out; he had hold of the tail and was pulling and Hector had hold of the inside of the machine and he was flexing - they're very strong".

Liz says she bears Hector no ill will, but she's not sharing a bathroom with him.
