A "Black Card" means "A card which, at an FIE competition, carries the penalty of exclusion from an event, suspension from the rest of the tournament and exclusion for the following two months of the current of following FIE season."
The Australian Fencing Federation has a "national black card" policy. As part of this policy there is a "State Reciprocal Black Card Policy" where a black card awarded by one state association is upheld by all members of the federation and they all conform the the national black card policy.
Information on the AFF and other state association policies can be found on the National Competition Rules and Policies page of the AFF website.
The ACTFA Black Card Policy is attached below.
