House renovations, gym workouts, young children, running to work, driving long distances to work, well rested by virtue of paxing for the last 4 hours.
Sounds like there's people here who are either currently commuting from the east coast now and trying to justify it or want a gig on the new toy but don't want to move to Perth.
A formal FRMS system will in all likelihood be introduced and the company may very well include commuting restrictions. It will, however, merely exist as an insurance policy.
CASA are too impotent to enforce it and management simply needs a fallback position in case you're late for work or (heaven forbid) have a whoopsie.
So you boys can relax and keep commuting from the east coast, hang around the terminal for 1, 2, 3, 4 hours and then operate, quite possibly back of the clock, to wherever.
