No one, I didn't have any success in opening your link.

CASA has confirmed that pilots will need to comply with the regulations of CASR 21.M to install "GoPro" type cameras on the external surface of an aircraft.
Under CASR 21.M (the old CAR35), a CASA authorised person has to approve the installation against existing airworthiness standards before the aeroplane can be flown.
"Attaching anything to the external surfaces of an aircraft, whether it is the wing or not, is considered a modification," CASA's spokesperson said.
"Depending on what is being attached, it may have an effect on the aerodynamics, structure and depending on its location it can affect the airspeed/altimeter readings, etc. Therefore, the alteration to the aircraft needs to be justified against the applicable airworthiness standard.
"Civil Aviation Regulations (CAR) 1988 regulation 35 was repealed approximately two years ago and replace by CASA Subpart 21.M. However, CASR Subpart 21.M has the same requirements as CAR 35 did.
"CASR Subpart 21.M does not disallow the installation of a modification or alteration to an aircraft, it is a regulation that allows design approval of the modification. CAR 42U requires any modification or repair to an aircraft to be installed in accordance with approved data. Therefore attaching a temporary modification must be done to 21.M approved data by an appropriately licenced person."
With the proliferation of GoPro-style cameras for videos and still shots, the issue has been bought into sharp focus, especially when those shots are published or put on websites.
