I know a cite for the Coolac Massacre.

Last monday at around 10am, on ABC Radio666 Canberra Morning Show presented by Alix Sloane, Alix had Ian Warden (UC) as a guest.  They had a phone in re Australian values and aussie trivia.  The show went right across NSW.  During it, it was said that the Coolac Massacre happened.  The tape of the show should be available.  I am sure Alix would oblige.
