Hi hotnhigh.
Yes, I agree there are merits of the independent umpire method vs. Julia doing it directly under 424 or whatever it is, but those things are largely unimportant to my argument.
Whichever way it is achieved, it means big business can circumvent PIA. It's as simple as that.
BHP or any number of large businesses operating in Australia could do the same thing tomorrow - shut down their entire Australian operations because of a little PIA, economy looks like it could be damaged - and BINGO! - FWA by application (or Julia directly) roll over in a matter of hours.
