Cablegram 124[A] LONDON, 16 August 1943, 7.28 p.m.
IMMEDIATE FOR THE PRIME MINISTER PERSONAL HIMSELF ONLY MOST SECRET
Developments are taking place both here and in America in
connection with what is known as the Tube Alloys scheme  which
apart from their significance in relation to the war will have
profound economic repercussions in the post-war period.
These developments are of so secret a character that I cannot
telegraph you with regard to them but Rivett  knows the general
picture and I suggest you should send for him and personally get
The main deposits of the raw material required  are in Canada
and the Belgian Congo, over both of which the Americans have
obtained control, and Australia. I suggest it is imperative that
the Australian deposits should be safe-guarded and that we should
be brought into the picture as to the present position and kept in
touch with all future developments.
To these ends I suggest that you should ask the United Kingdom
Government to agree that Professor Oliphant , who is leaving
here tomorrow for a short visit to America, should be allowed to
make a flying visit, in all senses of the term, to Australia for
consultation with you and your advisers.
For your very private information Oliphant would be willing to
make the trip and in fact is very much in favour of doing so.
