Sacked Wallabies star Israel Folau launched legal action Thursday against Rugby Australia’s decision to dismiss him over homophobic social media posts, saying he was defending freedom of religion.

“No Australian of any faith should be fired for practising their religion,” the devout Christian said in a statement after filing his case with Australia’s employment watchdog the Fair Workplace Commission.

Folau had his contract terminated last month after a Rugby Australia tribunal found him guilty of a “high-level” breach of the governing body’s code of conduct for posting that “hell awaits” gay people and others he considered sinners.
