Okihara,
You are a bit off beam in a couple of areas.
(1) Not all aircraft under 600 kg (the weight has varied over the years) are registered with RAOz.
(2) Not all aircraft registered with RAOz can be VH registered. For VH registration, the aircraft must fit into one of the categories of CASR 21.
(3) Even if you have a PPL, you still have to be a member of RAOz and check out and be issued with a RAOz pilot certificate to fly an RAOz aircraft.
All the "Rules of the Air" still apply to RAOz operations, except for a few critical exemptions. It is all controlled airspace, not just D.
Two of the major attractions of flying RAOs is the medical situation, private drivers license medical standard, and owners can, by and large, do their own maintenance.
Given CASA's propensity to order very expensive multiple medical tests for quite straightforward and common problems, a simple second class medical for somebody who is no longer in the bloom of youth can cost thousands of dollars annually, for an RAOz medical it is a visit to a GP, if you can legally hold a driver's license.
Tootle pip!!
PS: Be very clear, the statistics thoroughly illustrated that "standard" of medical held by a pilot has no relation to the accident/incident record, and this hold true even where a medical condition contributes to an accident or incident ---- ie: an current ATPL pilot with (obviously) a first class medical is no less likely to be involved in an in-flight medical occurrence than an RAOz certificate holder who can drive a motor car.
