I've two friends who've moved to Oz... one with her job, so easier (and her husband had no problems as he's Australian... ironically, he'd like to return to Blighty, whereas she's happy to stay put!). Can't see the attraction personally...
We turned our heating off Sunday when we left the house, so it'll be parky when we arrive. As it runs on fuel, every few days off saves plenty of € and no risk of freezing yet. Once it gets really cold, and last Christmas it got to -25°C at night, we leave it on lowest when we leave...
So while I'm settling the cats and unpacking, the other half's first job is to BUILD A FIRE! love it! The only problem is that we normally sit in front of it and vegetate... not such a good idea today though as we'll be there by 4pm!
