Does anyone know anything about if there is a problem at Yellomundie between riders and NPWS?

I have seen a few mentions here and there about negotiations between WSMTB and NPWS. On the Rocky Trail site I recently read something like "this could be the last big event at Yellomundie" referring to one of their events.

I cant work anything out from the WSMTB site, but does anyone know if Yellomundies future is in doubt?
