My telegram 783 of 10th December. 
We have no telegrams from Australian Charge d'Affaires, Tokyo , since Saturday last except short notification in clear that Japan had declared state of war with Australia received today.  We have telegraphed Argentine Ambassador, Tokyo , direct informing him that we have permitted Japanese Minister in Australia  to communicate in plain English with his Government and asking him to secure from Japanese Government permission to send and receive messages on behalf of Australian Charge d'Affaires at Tokyo.
Meantime we assume that you will advise us of any proposals regarding the evacuation of British, Commonwealth, American and Japanese diplomatic and consular officers. We would suggest that consideration be given to the possibility of evacuation through some neutral South American country.
