No you cant... not in and recreational aircraft.
Commercial aircraft have different rules.... some people just don't get it and I'm glad that I'm not flying anywhere near you if your understanding of the regulations are so poor.
it's in the CAO's, it is not in the RA-Aus technical manual as such because the CAO's define how many people can actually be in an RA-Aus registered aircraft and that is 2 people, no babies sitting on laps, no children in multiples in one adult seat etc... geeez
