The former Waratahs star was sacked by RA last month following an anti-homosexual social media post in April.
Folau, a devout Christian, uploaded an image on Instagram that said "hell awaits drunks, homosexuals, adulterers, liars, fornicators, thieves, atheists and idolators".
The 30-year-old had been warned for similar comments last year and was this time found guilty of a "high-level breach" of the governing body's code of conduct.
Folau did not appeal his dismissal but insisted he was not accepting the findings.
