Using hand carved canoes, they, along with dozens of Australians in kayaks, were able to prevent 10 scheduled ships from passing through the Newcastle coal port. 
Kwa kutumia ngalawa zilizotengenezwa kwa mkono, na kwa ushirikiano wa makumi ya wenyeji wa Australia, waliweza kuzuia meli kumi zilizokuwa zimepangwa kupita kwenye bandari ya Newcastle.
