Bloggs, Can't find the "tongue-in cheek" emoticon, but I would suspect Groggy was using it and I certainly was.
This is from the policy statement
https://infrastructure.gov.au/aviati...baro-vnav.aspx
APV Baro-VNAV operations require accurate aerodrome QNH (not area QNH) and temperature to be available. The QNH and temperature is measured by sensors on an Automatic Weather Station (AWS) and provided to the aircraft through an Aerodrome Weather Information Service (AWIS) with a VHF broadcast capability (referred to as an AWIS-VHF) or through an Automatic Terminal Information Service (ATIS) generally associated with Control Tower operations.
No mention of "automatic insertion" ..just good old ear-brain-hand coordination.
There is also the list of the proposed airports here

Temp Compensation needed if operating outside the Temp limits (at least that's how it is done elsewhere)
