The more I think about it, though, the more I'm convinced it was real and they've somehow managed to do the near-impossible by avoiding spoilers for a week.
I was at Old Melbourne Gaol (now a museum, and less than a block away from where I am right now) this morning, and the person I spoke to mentioned a Ned Kelly-related function on the Thursday night, telling me they had to clean everything up quickly because of "a very early start" on Friday morning, then quickly backtracking. The problem? It doesn't open to the public until 9:30am weekdays, which could hardly be considered "very early".
