For Oz Military airports (DN, LM, etc)

Defence Act 1903
Section 82 (1) 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.

For Civvy Airports
I have never seen a law in the CASRs or Transport Security Regs re photography at civvy airports. That will be up to the airport operator to determine and, as postulated above, is likely to ensure pundits stay on the straight line to the aircraft.

For those referring to Cabin Crew/ airline ground staff having no authority outside of the aircraft, may I remind you of the OPERATOR'S obligations under CASR 121.215 and 135.200.

​​​​​​​Procedures for safety at aerodromes
An aeroplane operator's exposition must include procedures to ensure the safety of persons in the vicinity of an aeroplane when any of the following circumstances apply: (a) a person is embarking or disembarking the aeroplane;

(b) a passenger is embarking or disembarking, or on board, the aeroplane while an engine of the aeroplane is operating but the aeroplane is not being flown or fuelled;

(c) the aeroplane is being loaded or unloaded;

(d) the aeroplane is being operated at an aerodrome.

---------
An airline employee absolutely has the authority to tell you not to stray off the line and if their manual determines that the taking of photographs cannot ensure the safety of passengers, then the airline rep has the right to tell you to stop.
