As a mark of respect and mourning for the many victims, including Australians, of the Malaysia Airlines tragedy, the Australian National Flag should be flown at half-mast all day on Saturday 19 July 2014. This advice applies to buildings and establishments occupied by Australian Government departments and affiliated agencies. Other organisations are welcome to participate.
In accordance with flag protocol, all flags and ensigns at each flag station should be flown at half-mast. However, should it be the custom to fly the flags of other nations at your flag station, it would be appropriate to seek permission from the diplomatic representatives of that nation to half-mast their flag.
