(CNN)A series of "unacceptable" homophobic and transphobic social media comments posted by Australian rugby player Israel Folau are being investigated by the sport's governing body.
On Instagram, the New South Wales Waratahs player shared an image listing "drunks, homosexuals, adulterers, liars, fornicators, thieves, atheists and idolaters," reading underneath, "Hell awaits you."
The 30-year-old Folau, who also plays for Australia's national team, captioned the image: "Those that are living in Sin will end up in Hell unless you repent. Jesus Christ loves you and is giving you time to turn away from your sin and come to him." He also included several Bible verses in the caption.
On Tuesday, Folau posted a transphobic reaction on social media to new legislation passed in Tasmania, which became the first Australian state to make listing gender on birth certificates optional. Those aged 16 and over can now apply to change their registered gender without the approval of their parents, while transgender people will no longer be denied official recognition of their gender until they've had surgery.
On Twitter, Folau shared a screenshot of an article about the legislation, writing: "The devil has blinded so many people in this world, REPENT and turn away from your evil ways."
In a statement on its website, Rugby Australia wrote: "Rugby Australia is aware of a post made by Israel Folau on his Instagram account this afternoon."
"The content within the post is unacceptable. It does not represent the values of the sport and is disrespectful to members of the Rugby community," the statement continued. "The Rugby Australia Integrity Unit has been engaged on the matter tonight."
