The Wonnerup massacre, also known as the Wonnerup "Minninup" massacre, was the killing of dozens of Wardandi Noongar people by European settlers in the vicinity of Wonnerup, Western Australia in February 1841.[1] The massacre on Wardandi-Doonan land in the south-west of Western Australia took place after Gaywal/Gaywaar, a Wardandi Man, speared and killed George Layman, a settler at Wonnerup on 21 February 1841. The leaders of the punitive massacre were Layman's neighbours John Bussell and Captain John Molloy, resident magistrate of the district. Settlers from the Wonnerup, Capel, Busselton and Augusta area joined them to commit "one of the most bloodthirsty deeds ever committed by Englishmen".[2]
