The traditional time for the transplanted Maleny festival was always Xmas - New Year.

The local council allegedly only allows them one Festival per year on the property, plus other "working party" weekends - which I hear are better: cause no spectators go, only the hard working talented folkie musos who pretend to plant trees, dig sewer lines, etc during the daytime, then drink and sing and drink and sing and drink and sing all night....
