I have aussie EIR and Eng/AF Licence. 5 trades. Now that Casa have dumbed down the avionics licence I have moved on from aviation. 22 years of study and now they give my qualifications away. Good news is I earn more working outside of aviation writing software, just wish I hadn't wasted those 22 years fixing planes.
The way to fix the skills shortage in Aus is improve the pay and working conditions of Lames, not import foreign underpaid slaves.
