During start up checks I make my call while the oil reaches an adequate temperature.
Me " Airfield radio, G-ABCD requesting airfield information and radio check"
Airfield "G-CD, Airfield Radio, QNH 1012, Runway in use 08 right hand circuit reading you fives"
Me "QNH 1012, Runway 08 right hand circuit, reading you fives (if they're also clear) G-CD"
So I mainly confirm that I'm reading the radio/tower as well. Not sure if it is the same in Oz but imagine it'd be similar.
