Factual error: The 4-wheel-drive Meredith van Aken is using to pick up Jonathan Cold and the black box has got a German registration plate for Berlin. However there are no discrimination letters after the "B" for Berlin, but a 5 digit number starting with "3." Only police cars carry registration plates like this in Berlin.
Factual error: In the film, many hostages and policemen are killed and wounded in the final shootout at Glenrowan. In actual fact, two hostages (Martin Cherry and John Jones) were killed and two more wounded, and on the police side only Superintendent Hare, an Aboriginal tracker and a civilian volunteer were wounded. There was no travelling circus present.
