When I evaluate this:
DayRange[DateObject[{2014, 1, 1}],
DateObject[{2014, 12, 31}], "Holiday",
HolidayCalendar -> "Australia"]
I get some incorrect dates listed as Australian holidays.

The problem seems to be that whoever or whatever collects these dates has failed to distinguish between national holidays and holidays for specific states or cities.
