SYDNEY A code of conduct hearing to determine the fate of Wallabies fullback Israel Folau will be held on May 4 after Rugby Australia's decision to sack him over anti-gay comments, it was announced Monday.

The devoutly religious Folau was informed last week of plans to terminate his multi-year, multi-million-dollar contract after posting on social media that "hell awaits" homosexuals.

Super Rugby's all-time record try scorer had the choice of accepting the decision or challenging it through a tribunal, and opted for the latter.

"Rugby Australia has today confirmed the code of conduct hearing for Wallabies and Waratahs back Israel Folau will commence on Saturday May 4," the governing body said.

It will be heard behind closed doors in Sydney by a three-member panel  John West, Kate Eastman, and John Boultbee  with an extra day set aside in case needed.

West is an employment law expert and senior counsel, while Eastman specialises in workplace discrimination. Boultbee is a lawyer and highly-regarded sports administrator.

They will consider the case and decide what punishment, if any, is appropriate  ranging from a fine to a suspension or the sack.

Folau asserted on his Instagram account that "hell awaits" "drunks, homosexuals, adulterers, liars, fornicators, thieves, atheists, idolators". 

It sparked widespread criticism, including from key Wallabies sponsor Qantas, with the scandal following a similar one last year in which he escaped sanction. 

Rugby Australia chief Raelene Castle has said Folau had been repeatedly warned about his social media use but ignored the overtures and refused to apologise.

She contends it was "a high-level breach" of the Professligious freedom issues could form part of his defence.

ional Players' Code of Conduct which warranted his contract being terminated.

Legal experts have suggested freedom of speech and re Folau  the sport's most marketable player before the row exploded  has played 73 times for the Wallabies and was a key part of their plans for the World Cup in Japan this year.

Wallabies coach Michael Cheika has said it is highly unlikely he would be picked again.
