A couple of people have talked about < 28 minutes between buses, or allowing an extra 30 minutes to get to work. I'm not sure where that information comes from.
My employer told us that buses are scheduled to be 12 minutes apart. The SACL
website quotes "Buses depart every 10 - 15 minutes and the trip to the terminal takes about 8 minutes, depending on traffic conditions" which seems accurate in practice, at least at this stage.
It used to take me 25 minutes garage-to-crewroom, now it seems to take 35 - 40 minutes for the same. Hardly worth getting union / CASA involved I would have thought.
Dedicated crew bus would be nice though.
