Cocas Palms have got to go

I have three dreaded Cocas Palms that need to be removed from the property that I am purchasing. I have conducted research on the net and it appears that the Cocas Palm has now been designated as a Noxious Weed in all but the Campbelltown Council area where I am purchasing the property. I have spoken to council and they have advised that they are a nuisance weed but have yet to be designated as noxious, this could be up to 5 or 6 years away. 

I have to make an application to be able to remove them, pay an application fee, and they will send out an inspector to assess them to see if I can get rid of them or not. 

I would be interested to hear from anyone else in the Campbelltown NSW council area that may have been able to remove these trees without having to apply to council. I have been told by others to just go ahead and do it but I dont want to risk a massive fine for the sake of a few trees.
