Navoff,
The answer to your last question ----- because that would be too simple and obvious.
One thing you will need to do is have a look at CAR 166, about operations around non-controlled aerodromes ---- which is most aerodromes in Australia --- and download or get a copy of the little book CASA publishes on the subject.
Even a simple position report does not follow the recommendations of Annex 10, Vol 11, or PANS/RAC 4444.
With one small exception (in UK - not Australia) the readback requirements are the same as CAP 413. If you stick to good UK (which is ICAO --- with only a very small number of differences filed with ICAO) radio practice, plus the requirements of CAR 166, you won't go too far wrong.
Beware of the strange idea that: " The faster you talk, the more professional you you are doubtless being". Don't accept the "invitation" of some "professional" pilots to indulge in "pilot arranged separation' --- do it yourself ATC, but stick to the recommendations for exchanging traffic information.
The trouble with "do it yourself" ATC is the mindset becomes that the participating aircraft are the only aircraft in the area. You do not have to give way to "larger" aircraft, the only aircraft that have a priority in Class G airspace are aircraft experiencing an emergency, and it is the right thing to do to give way to the RFDS/Air Ambulance. Beware of "larger" aircraft ignoring CAR 166 and "smaller" aircraft in the circuit . There are far too many pilots who thing the operating $$$ per hour establishes the priority for airspace or runway sequence.
Tootle pip!!
PS: Get the CASA books published for each capital city secondary airport, and read the instructions for the "Australian" so called Class D, the treatment of D as quasi C, with non-ICAO clearance requirements.
