As someone else pointed out - there is no shortage of qualified people.
There is a shortage of people here willing to join the race to the bottom or to work in an airline 'salt mine' environment.
The holes will be filled by 457 visa holders who see it as an easy entry ticket to Australia. Citizenship in 5 years and then off to better pastures.
You sacrifice a lot of quality family time working in aviation over the years. Most kids of pilots want nothing to do with it.
Yes another ramble.
