As OPEN DESC wrote its up to the ATO,no matter how long your rating lapsed,the cap 804 is a guide line and i guess it is for pilots who dont currently fly on the type.
(iv) expiry longer than 3 years: the applicant should again undergo the training required for the initial issue of the rating or, in case of helicopter, the training required for the ‘additional type issue’, according to other valid ratings held.
The word 'should' rather than 'shall' gives the choice to ATO.
Happy fishing
