Section 82 of the Defence Act states (link) :
"If:
(a) a person makes a sketch, drawing, photograph, picture or painting of any defence installation in Australia or of any part of one; and
(b) the person has no lawful authority to do so;
then:
(c) the person commits an offence; and
(d) all sketches, drawings, photographs, pictures, and paintings, and all tools and all materials or apparatus for sketching, drawing, photographing or painting found in his or her possession are forfeited and may be destroyed, sold, or otherwise disposed of, as the Governor‑General directs.
(1A) The maximum penalty for an offence under subsection (1) is imprisonment for 6 months or a fine of 2 penalty units, or both."
Having said that, I think there's some level of common sense applied especially in this day of smart phones with relatively high resolution cameras in them (even with shitty digital zoom). It's very easy to stand at Mrs Macquaries chair and take photos of MFUs alongside FBE. And in the past the RAAF has held air shows allowing professsionals with 800mm zooms to stand there and take photos of all their aircraft.
The fact is that imagery intel is collected by all and sundry and has been since the invention of the camera. Some do it better than others.
