Creamie,
Most countries, and Australia once did, comply with ICAO Annex 1, a few don't. and if you want to see how complicated it can be, have a look at the UK CAA version of how to log time as part of a "heavy crew". An accounting nightmare, goes double where "night" is involved.
As to ICAO definitions incorporated in the Air Navigation Act or the Civil Aviation Act, given the Commonwealth's significant dependence on the constitutional powers re. aviation, would a High Court be likely to change a definition that comes from our signing the Chicago Convention. That is a question I wouldn't even start to answer.
For private operations, FAA makes it easy, a pilot does not have to log anything in a pilot log book, unless he or she is making a claim for recency of some kind, or a license or rating.
Tootle pip!!
PS: I must go an have a look at the old definitions.
