Chris Elston, known as "Billboard Chris," has announced his legal appeal against the Australian government's directive to remove his post about Teddy Cook, a trans-identifying activist in Australia. 

Cook, who identifies as a man despite being biologically female, has faced controversy for posting on his social media content that includes public nudity, bondage parties, and bestiality, yet was appointed to a World Health Organization expert panel.

After Elston posted criticisms of Cook's activism on X, including the use of Cook's biological pronouns and other critiques, the Australian government ordered Elston to remove his post.

Elston's refusal to remove the post led the Australian government to threaten X with a substantial fine, prompting the social media platform to geo-block the content in Australia. However, X later announced plans to pursue legal action against the Australian government to protect users' free speech rights.

Now, Elston has also initiated legal proceedings against the Australian government, asserting his right to express criticism and opinions freely.

“I am legally appealing the Australian government’s attack on my speech which ordered X to remove my post concerning Teddy Cook, Australia’s resident ‘trans health expert.’” Elston posted on X.
