Although you can still totally book a stay in their house, I have no idea how they're keeping their rental property under wraps after the mayor literally called them out for "non-compliance," saying that instant hotels (or short-term rentals) have "no place" in Byron. 

The Gold Coast Bulletin reported that Byron's mayor accused Sam and James of having "a flagrant disregard for Byron Shire Council and thus, the community, which is charged with protecting the rights of residents against unlawful developments." "To see this property promoted on national television as an ‘instant hotel’ is extremely disappointing given it is not currently complying with council regulations," he went on to say.
