Folks,
The authority of the police, or the limits of their authority, is not quite as simple and black and white as some seem to believe.
In particular, in Queensland in quite recent times, the Crimes Act was amended to quite specifically include aircraft in the definition of a “vehicle”.
Queensland police have acted against “the driver of a vehicle” (my words, not the legal words) when the vehicle happened to be an aeroplane. One most interesting case involved low flying.
Fundamentally, aviation is State’s Rights, the Commonwealth’s power over aviation is limited, there is a long legal history going right back to only a few years after the dawn of aviation in Australia.
Don’t be in too much of a hurry to speak with great certainty in a very uncertain area.
Tootle pip!!
