Problem with that is sign on/off isn't at the carpark its at the terminal so any time waiting is on your time. I don't think there is any way you could have it considered as duty by CASA even though it is associated with work and your only means of getting to the terminal.
The major fatigue issue is for those who live a reasonable distance from the airport. If they want you to allow 30 mins for a bus followed by a 1 hour commute it starts becoming a bit of a fatigue issue. It would also limit where you can live and be employed at the airport as many airlines and the engineers only work daily shifts.
