Those are some cute Calls, priss! I love the bantam breeds. Mine tend to be more friendly than most of my large ducks. My Mini Appleyards especially do just what your Calls do, priss. They are the closest thing to "lap ducks" I have ever had. They will climb right into your lap looking for attention (or food, lol). I am not sure what small breeds you have in Australia, but in addition to the Appleyards (Silver bantams), my Australian Spotteds are also great as can be Mallards if any of those are available there. If noise is a factor at all, any of these might be good choices. I don't breed Calls so I don't have much to compare my bantams to in that regard, but mine are very quiet, much quieter than my full size ducks.
