Considering most pilots can't even complete their own tax return paperwork correctly, I don't think too many of them will be responding with detailed costings related to the depreciation and labour costs involved in running a jet airline operation. Most pilots wander into the discount tax return office with their shoe box full of receipts for their enormous wristwatches and expensive sunglasses, about 15 group certificates from the 15 employers that used them that year and a couple receipts for a renewal and that's the extent of their financial expertise.
I have no idea how this business will go in Australia but as far I'm concerned, this bloke is having a go and trying to make it happen so good luck to him.
