I know what you saying but the fact of the matter is the guys acted like thugs cause they are thugs.
Tony bourke and co are in the middle of crippleing the aquarium trade also with the same sort of science and message "were saving the native fish blah blah blah future generations blah blah" because they are going to introduce mandatory testing for some indovirus, that seems to have possibly started in australia anyway, which will basically mean that anyone who imports some aquarium fish will have to submit 5 of each species for tested at $250 a go.
I know of one lady who will have to close her shop (there will be 10 times that no that i dont know personally) and many importers whos buisnesses wont be viable anymore.
None of these people are going around using violence they are campaining hard during the month they have given for consultation.
