On 1 October 1818, approximately six Wodiwodi people were killed in a clash with nine settlers from the Colony of New South Wales along the Minnamurra River in the Illawarra, New South Wales.

The settlers claimed to have been attempting to recover two muskets which had been lent to some of the Aboriginal people which escalated into an armed clash. Local Dapto property owner, William Frederick Weston, his site overseer, Cornelius O'Brien, along with seven unknown convicts and labourers approached an Aboriginal campsite in the early hours of the morning, armed with muskets, swords and knives attached to long sticks. An armed clash resulted.^{[1][better source needed]}

The exact location of the massacre is disputed. Research led by Professor Lyndall Ryan, has led to an agreement^{[by whom?]} of the approximate location of the massacre site.^{[where?][2][3]}

In 2018, it was claimed that Kiama Council had plans to erect a permanent memorial of recognition along the proposed Minnamurra boardwalk, commemorated by a memorial service on the 200th year anniversary of the massacre.^[4]
