I have found the appropriate part of the Queensland Act (see below) which does at least give some precedent to any approach to NSW legislators, which I for one intend to make and hope others will also.
Body Corporate and Community Management Act 1997 (QLD)Chapter 5…
Part 3 Proxies for body corporate meetings—Act, section 103
106 Purpose of pt 3
The purpose of this part is to prescribe matters about the appointment and use of a proxy to represent a member of the body corporate at a general meeting of the body corporate.
107 Appointment
(1) A voter for the general meeting may appoint a proxy to act for the person at the general meeting.
(2) However, the body corporate may by special resolution prohibit the use of proxies—
(a) for particular things described in the special resolution;
or
(b) altogether.
(3) An appointment under subsection (1) has effect subject to the operation of a special resolution under subsection (2).
(4) A person must not hold—
(a) if there are 20 or more lots included in the community titles scheme—proxies greater in number than 5% of the lots;
or
(b) if there are fewer than 20 lots included in the scheme—more than 1 proxy.
