In 1926, Leopold Rupert Overheu and Frederick Hay jointly held the Nulla Nulla property near
Wyndham in the
Kimberley region of
Western Australia. Their property bordered the Forrest River Aboriginal Mission (later renamed
Oombulgurri) run by Reverend
Ernest Gribble. Over previous years, Frederick Hay had repeatedly taken and molested Aboriginal women with Gribble making complaints to authorities about his behaviour. In 1924, Hay had also seriously injured an Aboriginal man after hitting him over the head with his rifle butt. Hay and Overheu complained about the spearing of their cattle by local Aboriginal people, Overheu claiming the value of the speared cattle to be £10,000. In response, their property was declared a prohibited area under the 1905 Aborigines Act preventing indigenous people from entering or crossing it to reach other areas.
Initial massacre at Durragee On 18 May 1926, Overheu made a formal complaint that a large group of Aboriginal people were spearing cattle at Nulla Nulla. Constable James St Jack of the
Western Australia Police based at Wyndham was directed to investigate this killing of cattle. St Jack with his two Aboriginal assistants, Windie Joe and Jacob, set out from Wyndham and met up with Overheu and his Aboriginal servants Tommy Doort and Lyddie on the lower
Pentecost River. The group then travelled toward the Nulla Nulla property and camped for the night near Durragee Hill, close to where around 300 Aboriginal people were holding a ceremony on an island in the river. At dawn on 24 May 1926, St Jack armed Windie Joe, Jacob, and Tommy with shotguns and the patrol rushed the camp to disperse the indigenous people. Those who survived reported that many were injured and that two older men, Blui-Nua and Umbillie were killed by being beaten over the head with a stirrup iron or a rifle butt. An eyewitness to the Durragee Hill attack, Gladys Birch, many years later stated that several women and children were herded to the top of a cliff and pushed off while nine men were shot and thrown in a bonfire at Durragee. St Jack and Overheu testified later that they had shot no humans but had shot 31 dogs. However, witnesses described people being wounded by both bullets and shotgun pellets. After the dispersal at Durragee, the patrol continued to the Nulla Nulla Homestead arriving after dark to find Frederick Hay missing. The next morning Windie and Tommy were sent to try and find Hay. Hay's body was found later that same day north-east of the homestead.
The killing of Frederick Hay On 23 May 1926, an Aboriginal man named Lumbia and his child-wives, Anulgoo and Goolool, were resting at Johnson Billabong on the Nulla Nulla property when Hay rode up and demanded sex with Anulgoo. Hay then stripped down to his boots and raped her in front of Lumbia before indicating an intention to take her back to the Nulla Nulla with him. When Lumbia objected Hay attacked him with his stock-whip then broke his spears. Without bothering to dress Hay gathered his clothes, mounted his horse and began to ride off but Lumbia grabbed a broken shovel spear and stabbed him in the back with it, killing him. Anulgoo later stated that, during the argument, Hay had shot at Lumbia, and the bullet grazed his head. Hay's pistol was found to have a spent cartridge in the chamber. When Hay's body was found by the search party led by Constable St Jack, it had been largely consumed by predators and initially it could not be determined whether the remains were those of a white man or an Aboriginal person. According to the police report, the body still wore boots when found, which revealed white skin when removed. The district medical officer at Wyndham, Dr Arthur Adams, arrived from Wyndham two days later to conduct Hay's autopsy following which, due to the advanced state of decomposition, Hay was buried at the spot. St Jack and Overheu at this time had no knowledge that Lumbia had killed Hay and assumed that a large group of Aboriginal people were instead responsible for Hay's murder. On hearing of Hay's death, another armed group was organised at Wyndham where Richard Jolly and Bernard O'Leary were sworn in as special constables under the supervision of Constable Denis Regan. Overheu expressed that he wanted a strong armed force to go out and "deal drastically" with the local Aboriginal people. ==Forrest River punitive expedition==
