29 July – At Bega, New South Wales, Senior Constable Kenneth Desmond Coussens (31), his wife Elizabeth (34) and 7-month old son Bruce were instantly killed by a bomb placed on their homes veranda. The house was demolished by the explosion at about 2 AM. 8 year-old Roger McCampbell, Coussens step-son, survived. A six-gallon metal cream container filled with 240 sticks of gelignite, stolen from a mine, was placed there by Myron Bertram Kelly. Coussens dealt with Kelly regarding traffic offences and issued him several traffic fines. Kelly appears to have become angered because Coussens issued further fines and defect notices regarding Kelly’s tractor and rotary hoe. On 6 December 1957 Justice McClemens sentenced Kelly to life imprisonment for the 3 murders.
