Back to ozjet. Plan A - convert serious sums of cash amassed over the last 20 years in to a dream and watch it all go up in smoke as kero converts to noise on empty planes. Every successful aviation entrepreneur needs to do this at least once just for the experience of being stony broke. Builds character, especially in displaced employees who are then forced to go on to do things they would never have dreamed of.
Plan B - cash and dream bit as above, but find that of 14 million people living on the SE seaboard, there are just enough who will pay for kero and don't care as long as the noise is no worse than the neighbours harley, which is legal, right? Guvmint don't care about noise either, as they can tax it. Despite kero consumption and noise tax, airline breaks even. Pilots come and go, using it as a stepping stone to better things. Everybody is having fun, nobody getting rich, nodody on the dole. Owner doesn't care he's not getting rich as it's considered cool to have an airline and just how much money does one person need anyway?
Plan C - two years into plan B, along comes stage 4 noise rules, surprise surprise. No choice now, have to re-equip, but not enough money in it to justify going to the banks. But, being just a teensy weeny bit pissed off with the loss of at least some revenue, qantas or virgin figure another jetstar or njs type deal would not be a bad idea. So, flog old planes off to indonesia, lease newer ones at mates rates via customer airline. Or sell aoc as going concern to highest bidder, retire to spain, write memoirs.
