Biggles - if you look at the mandatory traffic information requirements imposed by Australia on IFR traffic when outside controlled airspace (which is A, C, D & E) then you will find that Australia does not have any Class G airspace. It is in fact Class F airspace, however CASA and Airservices refuse to use the correct category for reasons unknown to me.
Class G by definition is airspace where traffic information is given on a workload permitting basis; but not for our ATCs, they are required to give IFR traffic information. That, by definition is Class F and incidentally exactly what Australia had before the NAS changes; then we called it Flight Service.
What has actually happened is that CASA and Airservices, being full of ex-FSO/ATC people who love the old ways, have re-created the old ways but under the guise of the new airspace categories.
The more things change the more they stay the same! Vive la change!
