Anzac Day is a commemoration of the essential role of the political and legal institutions from England, Ireland, Scotland and Wales. It is an exclusive day of celebration and cannot be mixed with other Aboriginal and multicultural commemoration.
That said, it has been noticed recently the increasing participation of multicultural armed forces concelebrating the event in the capacity of marching members.
Regardless of any argument, the multicultural and foreign defence forces from Asia has no part in the history of Anzac. Marching together with Anzac veterans and their descendants can be considered an outright disrespect to its history and obscure the true meaning of Anzac day. If desired, a designated day (other than Anzac day) for a similar celebration can be legislated thru their lawmakers.
