Might work for Switzerland - not here. Our system of elected government is theoretically based on equality of one vote over another, and on each individual voter being a member of this nation first, and not of other nations, even internal 'nations' such as your personal ethnic or social group.
Your point raises an issue - should 'dual citizens' - who cannot stand for elected office here - be permitted the vote? SS-DD. If an elected representative must be Australian first and foremost - why then should dual citizens, with clearly divided loyalties, have the right to vote?

Earl McClung is Native American. He was one of two Native American scouts for the 101st Airborne. He signed up direct from the reservation when America was under attack - his 'First' Nation was secondary to the Nation as a whole. It is the same here.
Members of a certain group are absolutely free to elect their own representatives within and for that group in isolation - they do not and cannot have the right under our form of government to directly elect their own 'family' into parliaments... nor should they, for the simple reason that it unbalances discussion of issues.**
Muslims can have their 'spokesmen' (never women) - Aborigines can have their elders and spokespersons - these people can speak out and be heard - they have a 'voice' - in fact much more of a voice than any they claim is their opponent has - that should not translate into election to office by one group exclusive of all others.
I am one owner of the Belvoir Street Theatre in Sydney (not a shareholder - an owner same as Mel and Geoffrey etc) - at one time with board elections coming up, there was a push for an arbitrary position to be allocated to staff working for the theatre. I disagreed on the basis that staff already had a serious level of input into the operations of the theatre, same as a manager of an RSL need not be a Veteran and usually isn't, but still has massive influence on the operation of that club. Thus any allocated position was unnecessary and unbalanced the elected representative process through having an arbitrary installation of one or more members.
Put simply - the two 'arms' of government, administration and operation, should be separate, division of powers.
Sorry - can't go with you here.
** for my dedicated followers over the years - the same applies to the feminist (fringe sheilas and their lap dogs) invasion of parliament - it savagely unbalances any discussion of the relevant issues, and thus must be banned. They are essentially a 'nation' unto itself with divided loyalties, and thus put the whole arena out of kilter
