Non migrating dependants (MoFu) of PR applicants are required to undergo health checks (and character checks subject to age) .
If they are not MoFu, the CO can apply logic and determine that since they cannot be categorized as Mofu, then health and character will not be required but it is still good practice to correct on immiaccount to ensure decision ready application and less delay.
Definition of MoFu as follows:
spouse or de facto partner
Child or step child of the family head or of a spouse or de facto partner of the family head (other than a child or step child who is engaged to be married or has a spouse or de facto partner) and:
has not turned 18
or
has turned 18, but has not turned 23, and is dependent on the family head or on the spouse or de facto partner of the family head
or
has turned 23 and is under paragraph 1.05A(1)(b) dependent on the family head or on the spouse or de facto partner of the family head
Hope this helps.
