Avoid fishing in areas where fish feeding occurs or where fish species gather to spawn. Report any fish kills to your closest Environmental Protection Agency office . Fish feeding Most food fit for eating, particularly bread and meat, is generally not suitable for fish and may damage their health. Be aware that feeding fish may result in undesirably aggressive behaviour in some fish and can be dangerous to people in the water. Commercial tour operators are required to have a permit from the Great Barrier Reef Marine Park Authority and to follow strict guidelines.
Damage occurs most commonly from fins.
If you are inexperienced, try to practise snorkelling away from living coral. Be aware of where your fins are and avoid touching anything with them. Don't rest or stand on coral. If you must stand up, make sure it is on sand or use rest stations. Observe animals rather than handling them directly and avoid blocking the path of free swimming animals.
