Bringing goods into Australia you are specifically required to declare goods of plant or animal origin. Failure to do so is a criminal offence. If its unaccompanied household goods by container the rules and treatment are slightly different to the way things are handled through the airport since they are often fumigated or otherwise treated at the other end. Post is different again. But kendo / kumdo gear in good condition is not a problem (if the bokken or shinai has borer holes or drops dust on the counter when banged by an inspector you should not be using it anyway, its probably unsafe).
