As Keg touched on, unless rules are put in place around want you can't do before a duty (which would be impossible to do) then the whole issue about commuting and it's affect on fatigue is a dead argument.
Let's say we have a pilot is based in Sydney and lives on the Gold Coast and only a 10min easy drive to the airport. Allowing for their drive to the airport, check in time and flight time to Sydney their commute time would be around 2 hours. 1 hour of this commute time would be spent relaxing/sleeping on the flight down.
Now what if we have another pilot also based in Sydney and they live in Newcastle (or the southern highlands). Their drive to work on the best of days will be 2-3 hours, plus they have to put up with parking issues at the Blue Emu.
The pilot who has to drive 2-3 hours doesn't get the chance to relax/sleep like the pilot living on the Gold Coast does.
So which one is going to feel less tired (fatigued) at the start of their duty and after at the end of their duty?
