An audio recording has surfaced with billionaire mining magnate Andrew Forrest accusing Kerry Stokes’ media empire of biased and inaccurate reporting about his mining company FMG.

WA Business News reporter Matt McKenzie broke the revelation of simmering tensions between Mr Forrest and Mr Stokes before the audio was released.

Mr McKenzie told Gary Adshead the stoush is believed to have started after Forrest ordered mining trucks that weren’t from the Stokes-owned company Westrac.
