Flight Information service is a service provided for the purpose of giving advice and information useful for the safe and efficient conduct of flights.
(ICAO Annex 11: Air Traffic Services)
A flight information service may be provided on its own or in conjunction with an air traffic control service.

Flight information service includes the provision of pertinent:
-SIGMET and AIRMET information;
-Information concerning pre-eruption volcanic activity, volcanic eruptions and volcanic ash clouds;
-Information concerning the release into the atmosphere of radioactive materials or toxic chemicals;
-Information on changes in the serviceability of navigation aids;
-Information on changes in condition of aerodromes and associated facilities, including information on the state of the aerodrome movement areas when they are affected by snow, ice or significant depth of water;
-Information on unmanned free balloons; and,
-Any other information likely to affect safety.

as well as information concerning:
-Weather conditions reported or forecast at departure, destination and alternate aerodromes;
-Collision hazards, to aircraft operating in airspace Classes C, D, E, F and G;
-For flight over water areas, in so far as practicable and when requested by a pilot, any available information such as radio call sign, position, true track, speed, etc., of surface vessels in the area.

So, the relevant ones appear to be "in conjunction with an air traffic control service, "any other information likely to affect safety" and "collision hazards, to aircraft operating in airspace Classes C, D, E, F and G".

I'm not sure we (collective we) have established the class of airspace, G plus TCAS?

More likely the individual differences in technique, experience, interpretation, projection, prioritisation, judgement.

Fair point. Perhaps it's an issue for CASA, or DASA.

DASA
But DASA is responsible for enhancing and promoting the safety of military aviation. This is achieved through a Defence Aviation Safety Program (DASP), which supports compliance with statutory safety obligations and assures the effective management of aviation-safety risks. (my bolding)

Agreed. TRA, SID/STAR, NAP, RRO. What could go wrong? The latter two are certainly based on normal operations with ATC providing a control service. Given the majority of the traffic appears to be to/from the south then 29 only operations would provide more opportunities for profile separation segregation.
