It is a REQUIREMENT of the rescuer to perform mouth-to-mouth rescue breaths according to the Australian Resuscitation Guidelines.a. Trueb. False

According to the Australian Resuscitation Guidelines, the requirement for a rescuer to perform mouth-to-mouth rescue breaths can vary based on the context of the situation and the rescuer's training.

1. Current Guidelines: In many cases, compression-only CPR is recommended for adult victims of cardiorespiratory arrest. This means that if a rescuer is untrained or unsure, they may focus solely on chest compressions without providing rescue breaths.

2. Training Context: However, for trained rescuer scenarios, especially in cases involving children or specific drowning circumstances, mouth-to-mouth rescue breaths may be necessary and recommended.

3. Conclusion: Based on the general approach adopted by the Australian Resuscitation Guidelines, the statement that it is a requirement of the rescuer to perform mouth-to-mouth rescue breaths is False.

Final Answer: b. False.
