Mr DAVIDSON (DAWSON, QUEENSLAND) (Postmaster-General) - This is a matter concerning which the honorable member for

Werriwa has approached me in the last day or two, and on which I have already given him a reply. The reply is to the effect that it has been considered desirable, for security reasons, to place a ban on the use of languages other than English by amateur radio station operators. Such a ban was in operation until about 1953, and then was withdrawn at the request of the institute. My information is to the effect that it is desirable that this action should be taken, and I am guided by that information. The honorable member also asked whether it is the intention to extend the ban on the use of foreign languages to other avenues of communication. The reply is that it is not so intended.
