CAO 40.1.7 gives you....
The holder of an instructor rating may give instruction in
multi-engined aeroplanes only if he or she has:
(a) at least 50 hours as pilot in command on multi-engined aeroplanes, of
which:
(i) not more than 25 hours was acting in command under supervision;
and
(ii) at least 10 hours was as pilot in command on each type of aeroplane
in which he or she wishes to instruct or any other type that CASA
determines to be similar;
(b) passed an examination conducted by CASA, an approved testing officer or
an approved person; and
(c) holds an aircraft endorsement for the type of aeroplane.
So if you hold META, a type endorsement and have 10 hours on type, you are good to go..
...subject, of course, to any company requirements.
Good Luck!
