Apart from 'the principle of the thing', I assume ACMA is concerned 
about the range over which such jamming operates.

Relevantly to things I've been writing about lately, nearby drones 
could be comprehensively stuffed-up.

If anyone has solid info on such matters, I'd be delighted to (yet 
again) leverage off my link colleagues!  (Maybe off-list, since it's 
close to OT).
