From Right Minds:

The warrant claimed they had reason to believe I was in possession of a prohibited magazine fitted to a “.22RL lever action rifle. Blued metal, brown wooden stock.” The officer told me I had posted about it online, which I had—in my public written submission against the Firearms Amendment Act passed last year. That submission was shared on several blogs and social media. I had used the firearm as an example to prove the legislation was not targeting “military style assault weapons” as the media, prime minister, and her cabinet repeated ad nauseum. The vast majority of firearms affected by the legislation were just like mine.
