In late 1837, 4 white men were killed. The acting governor, Lieutenant Colonel Snodgrass sent Major James Nunn to the district to suppress the “outrageous acts”. From there 40 recruited stockman and rode around district, attacking and killing any aboriginals they could find.
Meanwhile at the Myall Creek station, when they had heard about the slaughtering in the district, around 45 aborigines had been camped for a few months. They were offered protection and food by the white settlers, in return for sexual acts by the women.

Over the 3 days prior to the massacre, the stockmen grouped around the creek and surrounding areas in preparation for the attack. The squatter also lead the fit and stronger men to cut bark on a nearby station therefore leaving the women, children and elderly men defenceless.
Approximately 27-30 aboriginals were killed here and were left until found by a passer-by. The sources indicate this is a result of the aboriginals frightening and killing the cattle.
