In August 2021, the Civil Aviation Safety Authority (CASA) released a multi-part Advisory Circular (AC), AC 91-19, AC 121-04-07, AC133-10, AC135-12 and 138-10 v1.0 (Passenger safety information), which provided additional guidance about the requirement for consistent information across formats:

3.3.3 The following considerations are relevant in this regard: − where there are differences between aircraft of the same type / model / series, e.g. the equipment carried on board or the equipment type is different, the safety cards used are specific to the aircraft − information contained in the card is consistent with information given in the safety briefings, the operator's procedures, and other information displayed in the aircraft, e.g. emergency exit markings and operating instructions that must be displayed.
The AC also covered briefing material related to cabin baggage and emergency escape slide use, stating that passengers should be advised to leave cabin baggage behind in an emergency in the pre-flight briefing and also in the pre-landing announcements.
