Oz statistics I've seen show that flying training is one of the safer parts of the GA spectrum.
Oz rules allow training to occur at any airfield - licenced or not - as long as the field meets the performance requirements for the a/c. There is no requirement for ATC / FISO / AG or fire services.
All schools require an ops manual in Oz and appopriate procedures pertaining to the use of the strips must be included.
Remove the requirement for training to be at a licenced airfield, thereby allowing schools to set up elsewhere and, more importantly, conduct normal training flights in to & out of these sorts of places.
Once such practice becomes the 'norm' then people are more likely to consider using it after their training because it will be something with which they're familiar.
It's very common in Oz for PPLs to head off to all sorts of bush strips for business & holiday. Sometimes just for a weekend, other times for weeks. One aero club I know has an annual fly-in to a country farm holiday place. Usually the a/c are booked months in advance. They even get ruled out for training for that weekend.
