^ I was thinking about this when I saw the news of the visit. I live near Melbourne and Victoria has indeed been avoided again.
Of course the different States have to become involved in a Royal visit, issue an formal invitation and take part in planning the itinerary. They are also up for part of the cost. I don't think the current Premier of Victoria, Daniel Andrews is a monarchist, so the non-invitation for Charles and Camilla is understandable if disappointing. However, Dennis Napthine, the man he defeated, a Liberal, was, and still Kate and William didn't come! It's a mystery!
