Your comment "irrelevent point" would seem to be also applicable to any reference to CCF. WA (or NZ) has no Myrtle Rust so should we be concerned about something that isn't here? As well CCF who you would expect are experts in tree management seem not to be concerned "do not have any ramifications for CCF's business model".
So CCF would appear to have no concerns (not that it's in WA anyway).
