The interesting thing about the relevant CAO, being CAO20.16.3, is it says 2 seaters can have 1 excess passenger - and it applies to all Australian registered aircraft. Not just those used for hire or reward.
While RAAus ops are exempted from pretty much all the CASR's, there's only a handful of the CAR's that they're exempt from, however, they are not exempt from complying with the CAO's, so CAO20.16.3 would apply.
If anyone can show me the RAAus Ops Manual chapter that says you must only carry one passenger, I'll happily admit I'm wrong. But I'm pretty sure you won't...
