I live in Bundaberg QLd it is not to cold here yet. The temperture is still 29 dgs durning the day here as I said it is a little cool at night but not cold... But at night I have a dark black material cover I cover Indigos cage and leave the front open.. I have Indigo in the rumpus room near my bedroom.....I use a light kids rug a light blanket and I still cover the sides and leave the front open as I turn out the lights on him. If I am watching TV I only have the light on so I can see the television in the lounge room.....What part of Australia do you come from?.Maybe someone else can give you some advice....
