Rugby Australia boss Raelene Castle denies Israel Folau's reported settlement

Rugby Australia boss Raelene Castle has denied reports suggesting its settlement with Israel Folau was AU$8 million.

On Thursday, the Daily Telegraph reported that Folau and his former employers had settled the ex-Wallaby's wrongful termination lawsuit for the large sum, although still $6 million less than he sought in compensation.

But Kiwi Castle has blasted the reports on her own social media.

"Folau settlement numbers are confidential but numbers being speculated are wildly inaccurate," Castle said in the short statement.

In his Sydney Morning Herald column, Australia media commentator Peter FitzSimons - also a former Wallaby - recently speculated that the sum would be nothing more than $300,000.

Folau, a former NRL star with the Melbourne Storm, sued Rugby Australia, after his contract was torn up earlier this year for a breach of contract.

The breach stemmed from social media comments from the devout Christian that claimed,"Hell awaits" a group of people including homosexuals, drunks and adulterers. 

The two sides entered court-ordered mediation this week and finally announced an agreement for a confidential amounton Wednesday.

Folau released a short YouTube video moments later, declaring he was "vindicated".
