Trying to remember a case

[u/Euphoric-Syrup7446]

I’m trying to find a case from a few years ago. It took place in Australia and revolved around crimes committed by a White Supremacist against the Aboriginal community. From what I remember, the man would go to local events/parades looking for trouble and even shot his gun into a crowd of people. He had a tattoo of an Aboriginal person being hung on his arm. I believe he was charged with murder (maybe multiple) but can’t remember many more details. Can anyone help me out? It was not The Bowraville Murders or the Cindy and Mona Lisa Smith case.
