Billionaire mining magnate Andrew Forrest has issued a blunt warning to the ARU - if you want to cut the Force, you are going to have to defeat me first.

The findings from last week's arbitration hearing between RugbyWA and the ARU is set to be handed down within days.

If the Force win, they will survive the axe until at least 2020.

But if they lose, the ARU is set to cull them from the Super Rugby competition.
