Heliringer,
CAR 5.88, privileges of a PPL:
5.88 What does a private pilot (helicopter) licence authorise a person to do?
(1) A private pilot (helicopter) licence authorises the holder of the licence:
(a) to fly a helicopter as pilot in command, or as co-pilot, while the helicopter is engaged in a private operation; and
(b) to fly a helicopter as pilot in command while the helicopter is engaged in flying training operations for the purpose of increasing the holder’s flying skill.
Last time I looked, mustering was classed as Aerial Work, not Private
It has to be Aerial Work to gain exemption for low level, etc, before that argument gets oxygen.
