Israel Folau case

Israel Folau case set to collide with Wallabies' Rugby World Cup campaign

Folau, 30, is suing RA and the NSW Waratahs for unlawful termination under the Fair Work Act, arguing RA tore up his four-year, multimillion-dollar contract was torn up because of his religion.

His legal team, led by Melbourne lawyer George Haros, filed the claim in the Federal Circuit Court late on Wednesday, after mediation failed before the Fair Work Commission in June.

The development has raised the prospect of a directions hearing taking place while Australia is in the thick of a tough World Cup campaign in Japan.
