To clarify, it's a documentary made by one of the survivors and to include survivor accounts etc, not a film as such, and probably only a short doco at that...
The memorial received funding back in 2011, I don't know if it's been installed yet. The doco was also completed back then, not in 2013.
Last November the Attorney -General was reported to be reviewing the evidence from the original inquest and it was announced back in March this year that the A-G would reopen the inquest.
