A 300,000 USD "package" may seem a lot to a low cost Australian pilot but it isn't really big money by international standards as a pilot and especially not an expat.
Legacy pilots in the states and other parts of Asia were making in excess of this a decade ago.
It's a package remember. Could include anything and I haven't cared to look. Also, the current $USD/AUD exchange rate may be relevant here but for many it is not. 300K USD is just that.
There's talk that the money is going to have to increase further.
