The robbery was not discovered until 7:30am the next day (23 November 1978) when a patrolling security officer noticed that the rear door was open. It then took bank staff, police, Chubb safe experts and finally local council workers nine hours, until 4:30pm, to open the safe and confirm that its contents had been stolen. This was despite a $250,000 reward on offer. Also in 1979, some of the money stolen from Murwillumbah was cashed in at a bank in
Hong Kong which then became the centre of an investigation trying to establish how much of money had been
laundered through there. Since the robbery it has been alleged that
Graham Kinniburgh, a safe cracker, was involved in the crime. However, in 2021 Robert Bertram “Bertie” Kidd, who has since died, claimed to have planned the robbery but to have been unable to attend on the night, as he was "unexpectedly detained in prison"; many do not believe this claim as all information shared by Kidd was well known. == In popular culture ==
