Assuming you are in NSW, all you have to do is nominate your husband, provided you are not standing for election yourself.
Otherwise, any other owner who is not standing for election can nominate him. In other words, anyone who is a non-owner can be elected provided they are nominated by an owner who is not standing for election.
This is what the Act says:
(4) A person is not eligible for election as a member of an executive committee unless the person is … (c) an individual who is not an owner but who is nominated for election by an owner who is not a candidate for election.
