The Australian Rugby Union has rejected an offer of around $50 million from billionaire mining magnate Andrew "Twiggy" Forrest to save the code and look after the financial burden of the Western Force.

Forrest, who first pledged support for the Western Force after the club's last match against the NSW Waratahs in July, was flanked by former ARU director Geoff Stooke and West Australia's first homegrown Wallaby, John Wellborn at the meeting. The trio met with ARU chairman Cameron Clyne, deputy chairman Brett Robinson as well as director and former Wallabies captain John Eales.

During a three-hour meeting in Adelaide, Forrest told the ARU there would be no financial risk to the game's governing body if the Force were able to continue in Super Rugby.

Fairfax Media has been told Forrest put an offer of around to $50million on the table to the ARU to help them out of financial trouble.
