That is one of the realities the Industry has to face-that being an Instructor must be recognised as critical and remunerated accordingly. As a TRI/TRE I receive a Training Allowance of $USD2800 pm net in addition to my salary as recognition that it is one of the most important and safety critical areas for the company. Not considering exchange rate a Senior Grade 1 Instructor with Testing Privileges should be earning the same ie $120k or $150k if you include exchange rates. Pay this and you will have made it a viable career option as now the remuneration would be adequate to stay teaching for people passionate about it.
