At this time of the year the cities and towns across Australia empty as the population begins the annual Christmas migration to the beach. It is the ultimate family daydream to own a beach shack with water views or if you can't afford to buy one then at least rent it for the two weeks around Christmas and into the new year. Sun, sand, surfing and copious amounts of seafood and alcohol. That's the way to celebrate Christmas in the Great Southern Land. Today I'm stalking the ultimate beach shack at the most easterly tip of Australia, in the celebrity holiday town of Byron Bay. Owned by the Arnott (biscuit) family it is known by the locals as "The White House". Time to check the biscuit jar for the extra coin though. Asking price is over $6 million AUD. Ouch! You can rent it for around $14 000 a week (Kate Moss and Elle Macpherson have). Save me a place on Boxing Day. I'll bring the prawns and champers. Link here while it lasts.
