This week Police arrested the president and seven members of the 28 Brotherhood MC gang.
There've been 43 arrests since February - including 20 baggage handlers.
Detective Inspector Tom Gollan says about 630 kilograms of meth and a hundred kilograms of cocaine have been seized.
He says you can just imagine the misery the seized drugs could have caused to our vulnerable communities had they gone on to be distributed around the country.
